Marching for Science with John Wilkins – a perspective from Philosophy of Science

Recent video interview with John Wilkins!

  • What should marchers for science advocate for (if anything)? Which way would you try to bias the economy of attention to science?
  • Should scientists (as individuals) be advocates for particular causes – and should the scientific enterprise advocate for particular causes?
  • The popular hashtag #AlternativeFacts and Epistemic Relativism – How about an #AlternativeHypotheses hashtag (#AltHype for short 😀 ?)
  • Some scientists have concerns for being involved directly – other scientists say they should have a voice and be heard on issues that matter and stand up and complain when public policy is based on erroneous logic and/or faulty assumptions, bad science. What’s your view? What are the risks?

John Wilkins is a historian and philosopher of science, especially biology. Apple tragic. Pratchett fan. Curmudgeon.

We will cover scientific realism vs structuralism in another video in the near future!
Topics will include:

  • Scientific Realism vs Scientific Structuralism (or Structuralism for short)
  • Ontic (OSR) vs Epistemic (ESR)
  • Does the claim that one can know only the abstract structure of the world trivialize scientific knowledge? (Epistemic Structural Realism and Ontic Structural Realism)
  • If we are in principle happy to accept scientific models (especially those that have graduated form hypothesis to theory) as structurally real – then does this give us reasons never to be overconfident about our assumptions?

Come to the Science March in Melbourne on April 22nd 2017 – bring your friends too 😀

All Aboard The Ship of Theseus with Keith Wiley

An exploration of the philosophical concept of metaphysical identity, using numerous variations on the infamous Ship of Theseus thought experiment.

Video interview with Keith Wiley

Note: a separate text interview is below.



Keith Wiley is the author of A Taxonomy and Metaphysics of Mind-Uploading, available on Amazon.

The ship of Theseus, also known as Theseus’ paradox, is a thought experiment that raises the question of whether an object that has had all of its components replaced remains fundamentally the same object. The paradox is most notably recorded by Plutarch in Life of Theseus from the late first century. Plutarch asked whether a ship that had been restored by replacing every single wooden part remained the same ship.

The paradox had been discussed by other ancient philosophers such as Heraclitus and Plato prior to Plutarch’s writings, and more recently by Thomas Hobbes and John Locke. Several variants are known, including the grandfather’s axe, which has had both head and handle replaced.

Note this is not a transcription of the video/audio interview.

The Ship of Theseus Metaphor

Adam Ford: Firstly, what is the story or metaphor of the Ship of Theseus intended to convey?

Keith Wiley: Around the first century AD, Plutarch wrote several biographies, including one of the king Theseus entitled Life of Theseus, in which he wrote the following passage:

The ship on which Theseus sailed with the youths and returned in safety, the thirty-oared galley, was preserved by the Athenians down to the time of Demetrius Phalereus. They took away the old timbers from time to time, and put new and sound ones in their places, so that the vessel became a standing illustration for the philosophers in the mooted question of growth, some declaring that it remained the same, others that it was not the same vessel.Plutarch

People sometimes erroneously believe that Plutarch presents the scenario (replacing a ship piecemeal style until all original material is absent) with a conclusion or judgment, i.e., that it makes some prescription of the “correct” way to interpret the scenario (as to, yes or no, is the ship’s identity preserved). However, as you see from the passage above, this is not the case. Plutarch left the question open. He mere poses the question and leaves it to the reader to ruminate on an actual answer.

The specific questions in that scenario are:

  • Does identity require maintaining the same material components? Aka, is identity tied and indicated by specific sets of atoms?
  • If not, then does preservation of identity require some sort of temporally overlapping sequence of closely connected parts?

The more general question being asked is: What is the nature of identity? What are its properties? What are its requirements (to claim preservation under various circumstances)? What traits specify identity and indicate the transformations under which identity may be preserved and under which it is necessarily lost?

Here is a video explainer by Keith Wiley (intended to inspire viewers to think about identity preservation)

Adam Ford: How does this story relate to mind uploading?

Keith Wiley: The identity of relatively static objects, and of objects not possessing minds or consciousness, is an introduction to the thornier question of metaphysical personal identity, i.e., the identity of persons. The goal in considering how various theories of identity describe what is happening in the Ship of Theseus is to prime our thinking about what happens to personal identity of people in analogous scenarios. For example, in a most straightforward manner, the Ship of Theseus asks us to consider how our identity would be affected if we replaced, piecemeal style, all the material in our own bodies. The funny thing is, this is already the case! It is colloquially estimated that our bodies turn over their material components approximately every seven years (whether this is precisely accurate is beside the point). The intent is not that a conclusion drawn from the Ship of Theseus definitively resolves the question concerning personal identity, because the former is a much simpler scenario. The critical distinction is that people are more obviously dynamic across time than static physical objects because our minds undergo constant psychological change. This raises the question of whether some sort of “temporal continuity” is at play in people that does not take effect in ships. There is also the question of whether consciousness somehow changes the discussion in radical ways. So the Ship of Theseus is not conclusive on personal identity. It is just a way to get us started in thinking about such issues.

Adam Ford: Fishing for clarification on how you use the term ‘identity’, Robin Hanson (scenario of uploads in the future in Age of Em) enquired about what kind of identity concept you are interested in. That is, what function do you intend this concept to serve?

Keith Wiley: Sure. First, and this might not be what Robin meant, there are different fundamental kinds of identity, two big ones being quantitative and numerical. Two things quantitatively identified possess the same properties, but are not necessarily “the same entity”. Two things numerically identical are somehow “the same thing”, which is problematic in its phrasing since they were admitted to be “two things” to begin with. The crucial distinction is in whether numerical identity makes any difference, or whether quantitative identity is all the fundamentally matters.

For me, I phrase the crucial question of personal identity relative to mind uploading in the following way: Do we grant equal primacy to claims to the original single identity to all minds (people) who psychologically descend from that common ancestral mind (person)? I always phrase it this way: granting primacy in claims to a historical identity. Do we tolerate the metaphysical interpretation that all descendant minds are equal in the primacy of their claim to the identity they perceive themselves to be? Alternatively, do we disregard such claims, dictating to others that they are not, in fact, who they believe themselves to be, and that they are not entitled to the rights of the people they claim to be? My concern is of:
bias (differing assignments of traits to various people),
prejudice (differing assignments of values, claims, or rights resulting from bias),
and discrimination (actions favoring and dismissing various people, resulting from prejudices).

Adam Ford: Is ‘identity’ the most appropriate word to be using here?

Keith Wiley: Well, identity certainly doesn’t seem to fully “work”. There’s always some boundary case or exception that undermines any identity theory we attempt to assign. My primary concern, such as it is on an entirely abstract philosophical musing (at this point in history when mind uploading isn’t remotely possible yet) is only secondarily the nature of identity. The primary concern, justified by those secondary aspects of identity, is whether we should regard uploads in some denigrated fashion. Should we dismiss their claims that they are the original person, that they should be perceived as the original person, that they should be treated and entitled and “enrighted” as the original person? I don’t just mean from a legal standpoint. We can pass all sorts of laws that force people to be respectful, but that’s an uninteresting question to me. I’m asking if it is fundamentally right or wrong to regard an upload in a denigrated way when judging its identity claims.

Ontology, Classification & Reality

Adam Ford: As we move forward the classification of identity will likely be fraught with struggle. We might need to invent new words to clarify the difference between distinct concepts. Do you have any ideas for new words?

Keith Wiley: The terminology I generally use is that of mind descendants and mind ancestors. In this way we can ask whether all minds descending from a common ancestral mind should be afforded equal primacy in their claim to the ancestral identity, or alternatively, whether there is a reasonable justification to exhibit biases, prejudices, and discriminations against some minds over such such questions. Personally, I don’t believe any such asymmetry in our judgment of persons and their identity claims can be grounded on physical or material traits (such as whose brain is composed of more matter from the ancestral brain, which comes up when debating nondestructive uploading scenarios).

Adam Ford: An appropriate definition for legal reasons?

Keith Wiley: I find legal distinctions to be uninteresting. It used to be illegal for whites and blacks to marry. Who cares what the law says from a moral, much less metaphysical, perspective. I’m interested in finding the most consistent, least arbitrary, and least paradoxical way to comprehend reality, including the aspect of reality that describes how minds relate to their mental ancestors.

Adam Ford: For scientific reasons?

Keith Wiley: I don’t believe this is a scientific question. How to procedurally accomplish uploading is a scientific question. Whether it can be done in a nondestructive way, leaving the original body and brain unharmed, is a scientific question. Whether multi-uploading (producing multiple uploads at once) is technically possible is a scientific question, say via an initial scan that can be multi-instantiated. I think those are crucial scientific endeavors that will be pursued in the future, and I participate in some of the discussions around that research. But at this point in history, when nothing like mind uploading is possible yet, I am pursuing other aspects, nonscientific aspects, namely the philosophical question of whether we have the correct metaphysical notion of identity in the first place, and whether we are applying identity theories in an irrational, or even discriminatory, fashion.

Implications for Brain Preservation

Adam Ford: Potential brain preservation (inc cryonics) customers may be interested in knowing the possible likely science of reanimation (which, it has been suggested, includes mind uploading) – and the type of preservation which will most likely achieve the best results. Even though we don’t have mind uploading yet – people are committing their brains to preservation strategies that are to some degree based on strategies for revival. Mummification? No – that probably won’t work. Immersion in saline based solution? Yeah for short periods of time. Plastination? Yes but only if it’s the connectome we are after… And then there is different methods of cryonic suspension that may be tailored to different intended outcomes – do you want to destructively scan the brain layer by layer and be uploaded in the future? Do you want to be able to fully revive the actual brain in the (potentially in a longer term future)?

Keith Wiley: People closer to the cryonics community than myself, such as some of my fellow BPF board members, claim that most current cryonics enthusiasts (and paying members or current subjects) are not of the mind uploading persuasion, preferring biological revival instead. Perhaps because they tend to be older (baby boomer generation) they have not bought into computerization of brains and minds. Their passion for cryonics is far more aligned with the prospect of future biological revival. I suspect there will be a shift toward those of a mind uploading persuasion as the newer generations, more comfortable with computers, enter the cryonics community.

As you described above, there are few categories of preservation and a few paths of potential revival. Preservation is primarily of two sorts: cryogenic and at least conceivably reversible, and room temperature and inconceivably reversible. The former is amenable to both biological revival and mind uploading. The latter is exclusively amenable to mind uploading. Why would one ever choose the latter option then? Simple: it might be the better method of preservation! It might preserve the connectome in greater detail for longer periods of time with lesser rates of decay — or it might simply be cheaper or otherwise easier to maintain over the long term. After all, cryonic storage requires cryonic facilities and constant nitrogen reintroduction as it boils off. Room temperature storage can be put on the shelf and forgotten about for millennia.

Adam Ford: What about for social (family) reasons?

Keith Wiley: This is closer to the area where I think and write, although not necessarily in a family-oriented way. But social in terms of whether our social contracts with one another should justify treating certain people in a discriminatory fashion and whether there is a rational basis for such prejudices. Not that any of this will be a real-world issue with which to tackle for quite some time. But perhaps some day…

Adam Ford: If the intended outcomes of BP are for subjective personal reasons?

Keith Wiley: I would admit that much of my personal interest here is to try to grind out the absolutely most logical way to comprehend minds and identity relative to brains, especially under the sorts of physical transformations that brains could hypothetically experience (Parfit’s hemispherical fission, teleportation, gradual nanobot replacement, freeze-slice-scan-and-emulate, etc.).


Adam Ford: In relation to appropriate definitions of ‘identity’ for scientific reasons – what are your thoughts on the whole map/territory ‘is science real’ debate? Where do you sit – scientific realism, anti-realism and structural realism (epistemic or ontic)? what’s your favorite?

Keith Wiley: I suppose I lean toward scientific realism (to my understanding: scientific claims and truths hold real truth value, not just current societal “perspective”, and further they can be applied to yet-to-be observed phenomena), although antirealism is a nifty idea (scientific truths are essentially those which we have yet to disprove, but expect to with some future overturning, or furthermore, unobserved phenomena are not reasonable subjects of scientific inquiry). The reason I don’t like the latter is it leads to antiintellectualism, which is a huge problem for our society. Rather than overturning or disregarding scientific theories, I prefer to interpret it as that we refine them, saying that new theories apply in corners where the old ones didn’t fit well (Newton’s laws are fine in many circumstances, but are best appended by quantum mechanics at the boundary’s of their applicability). Structural and ontic realism are currently vague to me. I’ve read about them but haven’t really grinded through their implications yet.

Adam Ford: If we are concerned about our future and the future of things we value we perhaps should ask a fundamental question: How do things actually persist? (Whether you’re a perdurantist or an endurantist – this is still a relevant question – see 5.2 ‘How Things Persist?’ in ‘Endurantism and Perdurantism’)

Keith Wiley: Perdurantism and Endurantism are not terms I have come across before. I do like the idea of conceptualizing objects as 4D temporal “worms”. I describe brains that way in my book for example. If this is the “right” way (or at least a good way) to conceive of the existence of physical objects, then it partially solves the persistence or preservation-of-identity problem: preservation of identity is the temporal stream of physical continuity. The problem is, I reject any physical requirement for explicitly *personal* identity of minds, because there appears to be no associated physical trait — plus that would leave open how to handle brain fission, ala Parfit, so worms just *can’*t solve the problem of personal identity, only of physical objects.

Adam Ford: Cybernetics – signal is more important than substrate – has cybernetics influenced your thinking? If so, how?

Keith Wiley: If by signal, you mean function, then I’ve always held that the functional traits of the brain are far more important (it not entirely more important) than mere material components.

Adam Ford: “signal is more important than substrate” – Yet the signal quality depends on the substrate – surely a ship’s substrate is not as tightly coupled to its function of moving across a body of water (wood, fiberglass, even steel will work) than a conscious human mind is to its biological brain. in terms of the granularity of replacement part – how much is needed?

Keith Wiley: Good question. I have no idea. I tend to presume the requisite level is action potential processing and generation, which is a pretty popular assumption I think. We should be open on this question at this time in history and current state of scientific knowledge.

Adam Ford: What level of functional representation is needed in order to be preserve ‘selfhood’?

Keith Wiley: Short answer: We don’t know yet. Long answer, it is widely presumed that the action-potential patterns of the connectome are where the crucial stuff is happening, but this is a supposition. We don’t know for sure.

Adam Ford: A Trolley Problem applied to Mind Uploaded Clones: As with the classic trolley problem, a trolley is hurtling down a track towards 5 people. As in the classic case, you can divert it onto a separate track by pulling a nearby leaver. However, suddenly 5 functionally equivalent carbon copies* of the original 5 people appear on the separate track. Would you pull the lever to save the originals but kill the copies? Or leave the originals to die, saving the copies? (*assume you just know the copies are functionally equivalent to the originals)

Keith Wiley: Much of my writing focuses on mind uploading and the related question of what minds are and what personal identity is. My primary claim is that uploads are wholly human in their psychological traits and human rights, and furthermore that they have equal primacy in their claim to the identity of the person who preceded an uploading procedure — even if the bio-original body and brain survive! The upload is still no less “the original person” than the person housed in the materially original body, precisely because bodies and material preservation are irrelevant to who we are, by my reckoning. If this is not the case, then how can we solve the fission paradox? Who gets to “be the original” if we split someone in two? The best solution is that only psychological traits matter and material traits are simply irrelevant.

So, for those reasons, I would rephrase your trolley scenario thusly: track one has five people, track two has five other people. Coincidentally, pairs of people from each track have very recently diverging memories, but the scenario is psychologically symmetrical between the two tracks even if there is some physical asymmetry in terms of how old the various material compositions (bodies) are. So we can disregard notions of asymmetry for the purpose of analyzing the moral or identity-preserving-killing implications of the trolley problem. It is simply “Five people on one track, five on another. Should you pull the lever, killing those on the diverted track to save those on the initial track?” That’s how I rephrase it.

Adam Ford: I wonder if the experiment would yield different results if there were 5 individuals on one track and 6 copies of 1 person on the other? (As some people suggest that copies are actually identical to the original – eg for voting purposes)

Keith Wiley: But they clearly aren’t identical in the scenario you described. The classic trolley problem has always implied that the subjects are reasonably alert and mentally dynamic (thinking). It isn’t carefully described so as to imply that the people involved are explicitly unconscious, to say nothing of the complexities involved in rendering them as physically static objects (preserved brains undergoing essentially no metabolic or signal-processing (action potentials) activity. The problem is never posed that way. Consequently, they are all awake and therefore divergent from one another, distinct individuals with all the rights of individual personhood. So it’s just five against six in your example. That’s all there is to it. People might suggest, as you said above, that copies are identical to each other (or to the original), but those people are just wrong.

So an interesting question then, is what if the various subjects involved actually are unconscious or even rigidly preserved? Can we say their psychological sequences have not diverged and that they therefore represent redundant physical instantiations of a given mind? I explore this exact question in my book by the way. I think a case could be made that until psychological divergence (until the brains are rolling forward through time, accumulating experiences and memories) we can say they are redundant in terms of identity and associated person-value. But to be clear, if the bio-original was statically preserved, then uploaded or duplicated, and then both people were put on the train tracks in their preserved state, physically identical, frozen with no ongoing psychological experience, then I would be clear to state that while it might not matter if we kill the upload, it *also* doesn’t matter if we choose the other way and kill the bio-original! That is the obvious implication of my reasoning here. And in your case above, if we have five distinct people on one track (let’s stay everyone involved is statically preserved) and six uploads of one of those people on the other track, then we could recast the problem as “five on one track and one on the other”. The funny thing is, if we save the six and revive them, then, after the fact, we have granted life to six distinct individuals, but we can only say that after we revive them, not at the time of the trolley experiment when they are statically preserved. So now we are speculating on the “tentative” split personhood of a set of identical but static minds based on a later time when they might be revived. Does that tentative individuality grant them individuality while they are still preserved? Does the mere potential to diverge and individualize grant them full-blown distinct identity before the divergence has occurred? I don’t know. Fascinating question. I guess the anti-abortion-choice and pro-abortion-choice debate has been trying to sort out the personhood of tentative, potential, or possible persons for a long time (and by extension, whether contraception is acceptable hits the same question). We don’t seem to have all agreed on a solution there yet, so we probably won’t agree in this case either.

Philosophy of identity

Adam Ford: Retention of structure across atomic change – is identity the structure, the atomic composition, the atomic or structural continuum through change, or a mixture?

Keith Wiley: Depends on one’s chosen theory of identity of course. Body theory, psychological theory, psychological branching theory, closest continuer theory, 4D spacetime “worm” theory. There’s several to choose from — but I find that some more paradox-prone than others, and I generally take that as an indication of a weak theory. I’m a branchest, although the distinction from worm theory is, on some accounts, virtually indistinguishable.

Adam Ford: Leibniz thought about the Identity of indiscernibles (principle in ontology that no two things can have all properties the same) – if objX and objY share all the same properties, are they the same thing? If KeithX and KeithY share the same functional characteristics are they the same person?

Keith Wiley: But do they really share the same properties to begin with, or is the premise unfounded? When people casually analyze these sorts of scenarios, the two people are standing there, conscious, wondering if someone is about to pass judgment on them and kill them. They are experiencing the world from slightly different sensorial vantage points (vision, sound, etc.) Their minds are almost certainly diverged in their psychological state mere fractions of a second upon regaining consciousness. So they aren’t functionally identical in the first place. Thus the question is flawed, right? The question can only be applied if they are unconscious and rigidly preserved (frozen perhaps). Although I believe a case could be made that mere lack of consciousness is sufficient to designate them *psychologically* identical even if they are not necessarily physically identical due to microscopic metabolic variations — but I leave that subtly as an open question for the time being.

Adam Ford: Here is a Symmetric Universe counterexample – Max Black – two distinct perfect spheres (or two Ship of Theseuses) are two separate objects even though they share all the same properties – but don’t share the same space-time. What are your thoughts?

Keith Wiley: This is very close to worm theory. It distinguishes seemingly identical entities by considering their spacetime worms, which squiggle their way through different spacetime paths and are therefore not identical in the first place. They never were. The reason they appeared to be identical is that we only considered 3D space projection of their truly 4D spacetime structure. You can easily alias pairs of distinct higher-dimensional entities by looking only at their projections onto lower dimensions and thereby wrongly conclude that they are identical when, in fact, they never were to begin with in their true higher dimensional structure. For example, consider two volumes, a sphere and a cylinder. They are 3D. But project them onto a 2D plane (at the right angle) and you get two circles. You might wrongly conclude they are identical, but they weren’t to begin with! You simply ignored an entire dimension of their nature. That’s what the 4D spacetime worm says about the identity of physical objects.

However, once we dismiss any relevance or importance of physical traits anyway (because I reject body identity on the matter of personal identity, favoring psychological identity), then the 4D worm becomes more convoluted. The question then becomes, what sort of “time worm” describes psychological changes over time instead of physical, structure, and material changes over time? I think it’s as simple as: take an information pattern instantiated in a physical system (a brain), produce a second physical instantiation, and now readily conclude that the psychological temporal worm (just a temporal sequence of psychological states frankly) has diverged.

Adam Ford: Nice answer! – I’m certainly interested in hearing more about worm theory – I think this wikipedia source is about the same thing:
Do you have any personal writings I can point at in the text form of the interview?

Keith Wiley: Ah, I hadn’t heard that term before. Thanks for the reference. Well, I always refer to my book of course, and more recently Randal Koene and I published a paper in the Journal of Consciousness Studies this past March.

(See Free near-final version on arxiv

Adam Ford: David Pearce is skeptical that our we as in our subjects of experience are actually enduring metaphysical egos – he seems more of a stage theorist – that each moment of subjective experience is fleeting – only persisting through one cycle of quantum cohesion delimited by decoherence.

Keith Wiley: Hmmm, I see the distinction in the link to stage theorist you provided above, and I do not believe I am committed to a position on that question. I go both ways in my own writing, sometimes describing things as true 4D entities (I describe brains that way in my book) but also writing quite frequently in terms of “mind descendants of mind ancestors”. That phrasing admits that perhaps identity does not span time in a temporal worm, but rather that it consists of instantaneous time slices of momentary identity connected in a temporal sequence. Like I said, I am uncommitted on this distinction, at least for now.

Identity: Accidental properties vs Essential properties

Adam Ford: Is the sense of an enduring metaphysical ego really an ‘accidental property’ (based on our intuitions of self) rather than an ‘essential property’ of identity?

Keith Wiley: It is possible we don’t yet know what a mind is in sufficient detail to answer such a question. I confess to not being entirely sure what the question is asking. That said, it is possible that conscious and cognitively rich aliens have come up with a fairly different way of comprehending what their minds actually are, and consequently may also have rather bizarre notions of what personal identity is.

Note that in the video, I sometimes offer an answer to the question “Did we preserve the ship in this scenario?” and I sometimes don’t, simply asking the viewer “So did we preserve it or not? What do you think?” This is because I’m certainly not sure of all the answers to this question in all the myriad scenarios yet.

Adam Ford: This argument is criticized by some modern philosophers on the grounds that it allegedly derives a conclusion about what is true from a premise about what people know. What people know or believe about an entity, they argue, is not really a characteristic of that entity.
There may be a problem in that what is true about a phenomenon or object (like identity) shouldn’t be derived from how we label or what we know about it – the label or description isn’t a characteristic of the identity (map not the territory etc).

Keith Wiley: I would essentially agree that identity shouldn’t merely be a convention of how we arbitrarily label things (i.e., that labeling grants or determines identity), but rather the reverse, that we are likely to label things so as to indicate how we perceive their identity. The question is, does our perception of identity indicate truth, which we then label, or does our perception determine or choose identity, which we then label? I would like to think reality is more objective than that, that there at least some aspects of identity that aren’t merely our choices, but rather traits of the world that we discover, observe, and finally label.




A Taxonomy and Metaphysics of Mind-Uploading
The Fallacy of Favouring Gradual Replacement Mind Uploading Over Scan-and-Copy Research Gate:

The Endurance/Perdurance Distinction By Neil Mckinnon
Endurantism and Perdurantism for a discussion on 3 different ways on what these terms have been taken to mean :


Perdure – remain in existence throughout a substantial period of time; persisting in virtue of having both temporal and spatial parts (alternatively the thesis that objects are four dimensional and have temporal parts)
Endure – being wholly present at all times at which it exists (endurance distinct from perducance in that endurance has strict identity and perdurance has a looser unity relation (genidentity))
Genidentity – is an existential relationship underlying the genesis of an object from one moment to the next.
Gunk – In mereology, an area of philosophical logic, the term gunk applies to any whole whose parts all have further proper parts. That is, a gunky object is not made of indivisible atoms or simples. Because parthood is transitive, any part of gunk is itself gunk.


Keith Wiley has a Ph.D. in Computer Science from the University of New Mexico and was one of the original members of MURG, the Mind Uploading Research Group, an online community dating to the mid-90s that discussed issues of consciousness with an aim toward mind-uploading. He has written multiple book chapters, peer-reviewed journal articles, and magazine articles, in addition to several essays on a broad array of topics, available on his website. Keith is also an avid rock-climber and a prolific classical piano composer.

Also see Jennifer Wang’s (Stanford University) video as she introduces us to the Ship of Theseus puzzle that has bedeviled philosophy since the ancient Greeks. She tells the Ship of Theseus story, and draws out the more general question behind it: what does it take for an object to persist over time? She then breaks this ancient problem down with modern clarity and rigor.

Can We Improve the Science of Solving Global Coordination Problems? Anders Sandberg

Anders Sandberg discusses solving coordination problems:

anders-s-02_40_16_03-still042Includes discussion on game theory including:the prisoners dilemma (and the iterated form), the tit-for-tat strategy, and reciprocal altruism. He then discusses politics, and why he considers himself a ‘heretical libertarian’ – then contrasts the benefits and risks of centralized planning vs distributed trial & error and links this in with discussion on Existential Risk – centralizing very risky projects at the risk of disastrous coordination failures. He discusses groupthink and what forms of coordination work best. Finally he emphasises the need for a science of coordination – a multidisciplinary approach including:

  1. Philosophy
  2. Political Science
  3. Economics
  4. Game Theory

Also see the tutorial on the Prisoners Dilemma:

And Anders paper on AGI models.

A metasystem transition is the evolutionary emergence of a higher level of organisation or control in a system. A number of systems become integrated into a higher-order system, producing a multi-level hierarchy of control. Within biology such evolutionary transitions have occurred through the evolution of self-replication, multicellularity, sexual reproduction, societies etc. where smaller subsystems merge without losing differentiation yet often become dependent on the larger entity. At the beginning of the process the control mechanism is rudimentary, mainly coordinating the subsystems. As the whole system develops further the subsystems specialize and the control systems become more effective. While metasystem transitions in biology are seen as caused by biological evolution, other systems might exhibit other forms of evolution (e.g. social change or deliberate organisation) to cause metasystem transitions. Extrapolated to humans, future transitions might involve parts or the whole of the human species becoming a super-organism.Anders Sandberg

Review of Homo Deus: A Brief History of Tomorrow by Yuval Noah Harari – Steve Fuller

Sapiens, a breif history of humankind - Yuval Noah HarariMy sociology of knowledge students read Yuval Harari’s bestselling first book, Sapiens, to think about the right frame of reference for understanding the overall trajectory of the human condition. Homo Deus follows the example of Sapiens, using contemporary events to launch into what nowadays is called ‘big history’ but has been also called ‘deep history’ and ‘long history’. Whatever you call it, the orientation sees the human condition as subject to multiple overlapping rhythms of change which generate the sorts of ‘events’ that are the stuff of history lessons. But Harari’s history is nothing like the version you half remember from school.

In school historical events were explained in terms more or less recognizable to the agents involved. In contrast, Harari reaches for accounts that scientifically update the idea of ‘perennial philosophy’. Aldous Huxley popularized this phrase in his quest to seek common patterns of thought in the great world religions which could be leveraged as a global ethic in the aftermath of the Second World War. Harari similarly leverages bits of genetics, ecology, neuroscience and cognitive science to advance a broadly evolutionary narrative. But unlike Darwin’s version, Harari’s points towards the incipient apotheosis of our species; hence, the book’s title.

This invariably means that events are treated as symptoms if not omens of the shape of things to come. Harari’s central thesis is that whereas in the past we cowered in the face of impersonal natural forces beyond our control, nowadays our biggest enemy is the one that faces us in the mirror, which may or may not be able within our control. Thus, the sort of deity into which we are evolving is one whose superhuman powers may well result in self-destruction. Harari’s attitude towards this prospect is one of slightly awestruck bemusement.

Here Harari equivocates where his predecessors dared to distinguish. Writing with the bracing clarity afforded by the Existentialist horizons of the Cold War, cybernetics founder Norbert Wiener declared that humanity’s survival depends on knowing whether what we don’t know is actually trying to hurt us. If so, then any apparent advance in knowledge will always be illusory. As for Harari, he does not seem to see humanity in some never-ending diabolical chess match against an implacable foe, as in The Seventh Seal. Instead he takes refuge in the so-called law of unintended consequences. So while the shape of our ignorance does indeed shift as our knowledge advances, it does so in ways that keep Harari at a comfortable distance from passing judgement on our long term prognosis.

Homo Deus YuvalThis semi-detachment makes Homo Deus a suave but perhaps not deep read of the human condition. Consider his choice of religious precedents to illustrate that we may be approaching divinity, a thesis with which I am broadly sympathetic. Instead of the Abrahamic God, Harari tends towards the ancient Greek and Hindu deities, who enjoy both superhuman powers and all too human foibles. The implication is that to enhance the one is by no means to diminish the other. If anything, it may simply make the overall result worse than had both our intellects and our passions been weaker. Such an observation, a familiar pretext for comedy, wears well with those who are inclined to read a book like this only once.

One figure who is conspicuous by his absence from Harari’s theology is Faust, the legendary rogue Christian scholar who epitomized the version of Homo Deus at play a hundred years ago in Oswald Spengler’s The Decline of the West. What distinguishes Faustian failings from those of the Greek and Hindu deities is that Faust’s result from his being neither as clever nor as loving as he thought. The theology at work is transcendental, perhaps even Platonic.

In such a world, Harari’s ironic thesis that future humans might possess virtually perfect intellects yet also retain quite undisciplined appetites is a non-starter. If anything, Faust’s undisciplined appetites point to a fundamental intellectual deficiency that prevents him from exercising a ‘rational will’, which is the mark of a truly supreme being. Faust’s sense of his own superiority simply leads him down a path of ever more frustrated and destructive desire. Only the one true God can put him out of his misery in the end.

In contrast, if there is ‘one true God’ in Harari’s theology, it goes by the name of ‘Efficiency’ and its religion is called ‘Dataism’. Efficiency is familiar as the dimension along which technological progress is made. It amounts to discovering how to do more with less. To recall Marshall McLuhan, the ‘less’ is the ‘medium’ and the ‘more’ is the ‘message’. However, the metaphysics of efficiency matters. Are we talking about spending less money, less time and/or less energy?

It is telling that the sort of efficiency which most animates Harari’s account is the conversion of brain power to computer power. To be sure, computers can outperform humans on an increasing range of specialised tasks. Moreover, computers are getting better at integrating the operations of other technologies, each of which also typically replaces one or more human functions. The result is the so-called Internet of Things. But does this mean that the brain is on the verge of becoming redundant?

Those who say yes, most notably the ‘Singularitarians’ whose spiritual home is Silicon Valley, want to translate the brain’s software into a silicon base that will enable it to survive and expand indefinitely in a cosmic Internet of Things. Let’s suppose that such a translation becomes feasible. The energy requirements of such scaled up silicon platforms might still be prohibitive. For all its liabilities and mysteries, the brain remains the most energy efficient medium for encoding and executing intelligence. Indeed, forward facing ecologists might consider investing in a high-tech agronomy dedicated to cultivating neurons to function as organic computers – ‘Stem Cell 2.0’, if you will.

However, Harari does not see this possible future because he remains captive to Silicon Valley’s version of determinism, which prescribes a migration from carbon to silicon for anything worth preserving indefinitely. It is against this backdrop that he flirts with the idea that a computer-based ‘superintelligence’ might eventually find humans surplus to requirements in a rationally organized world. Like other Singularitarians, Harari approaches the matter in the style of a 1950s B-movie fan who sees the normative universe divided between ‘us’ (the humans) and ‘them’ (the non-humans).

The bravest face to put on this intuition is that computers will transition to superintelligence so soon – ‘exponentially’ as the faithful say — that ‘us vs. them’ becomes an operative organizing principle. More likely and messier for Harari is that this process will be dragged out. And during that time Homo sapiens will divide between those who identify with their emerging machine overlords, who are entitled to human-like rights, and those who cling to the new acceptable face of racism, a ‘carbonist’ ideology which would privilege organic life above any silicon-based translations or hybridizations. Maybe Harari will live long enough to write a sequel to Homo Deus to explain how this battle might pan out.

Video Interview with Steve Fuller covering the Homo Deus book

Steve fuller discusses the new book Homo Deus, how it relates to the general transhumanist philosophy and movementfactors around the success of these ideas going mainstream, Yuval Noah Harari’s writing style, why there has been a bias within academia (esp sociology) to steer away from ideas which are less well established in history (and this is important because our successfully navigating the future will require a lot of new ideas), existential risk, and we contrast a posthuman future with a future dominated by an AI superintelligence.

Discussion on the Coursera course ‘A Brief History of Humankind’ (which I took a few years ago):

Is Infinity Real?

There is an interesting discussion at Quanta “Solution: ‘Is Infinity Real?’” – Is infinity a real physical phenomenon outside our models? Max Tegmark doesn’t think so – while admitting it is indisputably useful for mathematical models of physics, he believes that nothing is truly continuous – including space and time.
infinity_500Would an infinitely X* phenomenon be amenable to observational evidence? Perhaps not – and if so, we can never count one infinity, making it difficult to assign a likelihood that infinity exists in the territory and not as just convenient approximations in our maps.
Max believes also there are good philosophical reasons to ditch infinity and pitfalls in assuming infinity in mathematical models. Four points that should be understood (which are detailed in the linked Quanta article):
1. The map is not the territory.
2. Infinity is valid in mathematical models and can be very useful.
3. In the physical world, there are compelling practical and philosophical reasons to reject infinity as a default assumption.
4. There will be limiting cases where the mathematical infinity assumption and the physical absence of infinity result in different answers.
Finite models are proposed as solutions to replace infinite solutions for a few mathematical problems: Hilbert’s hotel, the 100, 200, 300 Triangle, and the Elliptical Pool Table.
“So the bottom line is: Infinity is permissible in mathematics applied to physics because it makes things convenient and tractable in most cases. However, we must be alert for limiting cases where our models are bound to fail, and we will then need to apply different methods.”
*X could represent huge, small, powerful etc..
I had a discussion about this with a friend Adam Karlovsky – and I was surprised when this just came up on my radar – it’s an interesting read.  We discussed the possibility that infinite randomness would produce an infinite amount of copies of Adam Karlovsky – doing an infinite amount of things.  He said that at one stage this thought kept him up at night.  I have had my doubts about the realism of infinity.

So what do you think?

Should We Re-Engineer Ourselves to Phase Out our Violent Nature?

team-david-pearceDavid Pearce reflects on the motivation for human enhancement to phase out our violent nature. Do we want to perpetuate the states of experience which are beholden to our violent default biological imperatives .. or re-engineer ourselves?

Crudely speaking – and inevitably this is very crudely speaking – that nature designed men, males, to be hunters and warriors – and we still have to a very large degree a hunter/warrior psychology. This is why men are fascinated by conflict & violence – why we enjoy watching competitive sports.
Now although ordinary everyday life for many of us in the world is no longer involves the kind of endemic violence that was once the case (goodness knows how many deaths one will witness on screen in the course of a lifetime) one still enjoys violence and quite frequently watch men being very nasty towards each other – competing against each other.
Do we want to perpetuate these states of mind indefinitely? Or do we want to re-engineer ourselves?David Pearce


Materialism vs Physicalism (and Strawsonian Physicalism) with David Pearce

team-david-pearceDavid Pearce (interviewed by Adam Ford) discusses the difference between Physicalism & Materialism – and also discusses Strawsonian Physicalism – the idea that consciousness discloses the intrinsic nature of the physical. May answer which breathes fire into the equations.
What makes our minds distinctive – isn’t that we are composed of novel stuff (along the conjecture that we everything is made up of fields of experience) – is that they support bound phenomenal consciousness. A Neurosurgeon may detect modules in the brain that are responsible for many things (vision processing, auditory perception, etc) but they can’t – for whatever reason – find that they are bound in phenomenal objects apprehended by a unitary phenomenal self.



One reason that many philosophically literate scientists and scientifically literate philosophers describe themselves as ‘physicalists’ is that they recognize that – for example bosinic forcefields, dark matter, dark energy – aren’t matter in a conventional sense – nonetheless the positions are clearly (most philosophers and scientists would say are) close cousins.  But if we are to be physicalists in that sense – then the so-called ‘hard problem of consciousness’ arises and in ‘explanatory gap’ and there doesn’t seem to be any way to accommodate consciousness within this explanatory theme.  But I think two separate claims need to be teased out from physicalism:
1) is the claim that physics discloses the actual nature of the stuff of the world – the fundamental entities – whether they are particles or fields or super-strings or branes.
2) the other is the claim that equations of physics and their solutions exhaustively describe the behavior of the stuff of the world
And they are distinct claims and should be separated because, for example a field in physics is defined purely mathematically and as the well known materialist – say outspoken materialist – like Stephen Hawking puts it quite poetically ‘We have no idea what breathes fire into the equations and makes there a universe for us to describe.  So, yes, one conjecture that we might call ‘Strawsonian Physicalsim‘ (after one of it’s best known proponents) is the idea that consciousness actually discloses the intrinsic nature of the physical – that is it possible consistently to maintain (that as Hawking would do) that we have no idea what breathes fire into the equations, and at the same time claim that this fire has no phenomenal properties – this is a particularly pertinent question given that the one part, the one tiny part, of the fire in the equations – the intrinsic essence of the stuff of the world which we do have access, namely our own minds – has properties that are at radically in-variance from what one might imagine on a standard materialist ontology.  And I would certainly argue that what makes our minds distinctive isn’t that we are composed of some novel kind of stuff – on the contrary that everything is ultimately fields of experience – but what makes our minds different I would say is that they support bound phenomenal consciousness – that a neurosurgeon that was inspecting your brain would reveal a distributively processed edges, textures, motions, colours etc in your brain – but somehow, for reasons that are not understood, the are bound into phenomenal objects apprehended by a unitary phenomenal self – you.  And so, yes, if one is a Strawsonian Physicalist – which of course is a very bold claim, this is not animism or vitalism, it’s not claiming rocks or chairs or tables or trees are subjects of experience or anything like that – it’s a conjecture about the fundamental stuff of the world – could it be fields of phenomenal simples that the equations of physics exhaustively describes?
And I see a progress in the problem of consciousness and explaining why we’re not zombies is going to come by solving the binding problem – but a precondition of solving the binding problem – I think – is to accept something like Strawsonian Physicalism.
Adam Ford: Ahh that’s interesting – you mention ‘fields of experience’ – would that be compatible with a ‘panpsychist’ view of universe?
david_pearceDavid Pearce: Yes, I think it’s – to some extent this is a stipulative definition – but I think it’s worth distinguishing panpsychism – the idea that, in some sense, experience is attached to the fundamental physical properties – all the fundamental physical properties of the world – and what sounds extremely similar to ‘idealism’ – the view that experience discloses the intrinsic nature of the physical, the intrinsic stuff of the world – so, yes there are clearly affinities between the two positions – but yes, it is in principle at any rate possible to reconcile physicalism and an ontology of idealism – so what we were discussing earlier on how physicalism and materialism  being cousins, in fact there is no need for them to be cousins at all. Because this is a very bold claim if one uses the term ‘idealism’ most people will think of bishop Barklay “to be is to be perceived” – that reality is somehow mind dependent. Or alternatively perhaps the idealism of the German school of idealists in the 18th & 19th century – but this particular conjecture, as I said – it’s physicalist that accepts that the formalism of physics – the mathematical straight jacket of theoretical physics – is complete, but claims that the actual intrinsic nature of the physical is experience in it’s most rudimentary sense – which is wildly counter-intuitive. But as long as even physicists won’t claim that they know the intrinsic nature of the fire in the equasions – Kant’s Noumenal Essence of the world so to speak – then it’s very much up for grabs – and we know that something must be wrong with our conceptual scheme because currently we are quite incapable of explaining consciousness within a materialist framework.

Watch the interview with David Pearce video here.

Physicalistic Idealism
Does reductive physicalism entail monistic idealism?
A testable conjecture about the nature of the physical world.

Natural science promises a complete story of the world. No “element of reality” should be missing from the mathematical formalism of physics, i.e. relativistic quantum field theory or its more speculative extensions. The Standard Model is extraordinarily well tested. Within its conceptual framework, consciousness would seem not only causally impotent but physically impossible. Hence the “Explanatory Gap” and the Hard Problem of consciousness.

In recent years, a minority of researchers have proposed that the Hard Problem may be an artifact of materialist metaphysics. Contra Kant, but following Schopenhauer, Russell, Lockwood, Strawson, et al., the new idealists conjecture that the phenomenology of one’s mind reveals the intrinsic nature of the physical – the elusive “fire” in the equations about which physics is silent. Our ordinary presupposition that the intrinsic character of the physical is devoid of phenomenal properties is an additional metaphysical assumption. This is hugely plausible, for sure, but not a scientific discovery. Perhaps most tellingly, the only part of the “fire” in the equations to which one ever enjoys direct access, i.e. one’s own consciousness, discloses phenomenal properties that are inconsistent with a materialist ontology.

David Pearce - Healesville SanctuaryUntestability cuts both ways. Any conjecture that the world’s fundamental quantum fields – and, presumably, fundamental macroscopic quantum phenomena such as superconductors or superfluid helium – are intrinsically experiential would seem unfalsifiable too: just speculative metaphysics.

Rather surprisingly, we shall see this isn’t the case.

Is there a Meaningful Future for Non-Optimal Moral Agents?

In an interview last year, I had a discussion with John Danaher on the Hedonistic Imperative & Superintelligence – a concern he has with HI is that it denies or de-emphasises some kind of moral agency – in moral theory there is a distinction between moral agents (being a responsible actor able to make moral decisions, influence direction of moral progress, shapes its future, and owes duties to others) and moral patients who may be deemed to have limited or no grounds for moral agency/autonomy/responsibility – they are simply a recipient of moral benefits – in contrast to humans, animals could be classified as moral patients – (see Stanford writing on Grounds for Moral Status).

As time goes on, the notion of strong artificial intelligence leading to Superintelligence (which may herald in something like an Intelligence Explosion) and ideas like the hedonistic imperative becomes less sensational sci-fi concepts and more like visions of realizable eventualities. Thinking about moral endpoints comes to me a paradoxical feeling of triumph and disempowerment.

John’s concern is that ensuring the well-being of humans (conscious entities) is consistent with denying their moral agency – minimizing their capacity to act – that there is a danger that the outcome of HI or an Intelligence Explosion may result in sentient life being made very happy forever, but unable to make choices – with a focus on a future entirely based on bliss whilst ignoring other aspects of what makes for a valuable or worthwhile existence.

Artificial Heart chipsSo even if we have a future where a) we are made very happy and b) we are subject to a wide variety of novelty (which I argue for in Novelty Utilitarianism) without some kind of self-determination we may not be able to enjoy part of what arguably makes for a worthwhile existence.

If the argument for moral agency is completely toppled by the argument against free will then I can see why there would be no reason for it – and that bliss/novelty may be enough – though I personally haven’t been convinced that this is the case.

Also the idea that moral agency and novelty should be ranked as auxiliary aspects to the main imperative of reducing suffering/increasing bliss seems problematic – I get the sense that they (agency/novelty) could easily be swapped out for most non-optimal moral agents in the quest for -suffering/+bliss troublesome.
The idea that upon evaluating grounds for moral status, our ethical/moral quotient may not match or even come close to a potential ethical force of a superintelligence is also troubling. If we are serious about the best ethical outcomes, when the time comes, should we be committed to resigning all moral agency to agents that are more adept at producing peek moral outcomes?
ancillary-one-esk-glitchIs it really possible for non-optimal agents to have a meaningful moral input in a universe where they’ve been completely outperformed by moral machines? Is a life of novelty & bliss the most optimal outcome we can hope for?

There probably should be some more discussion on trade-offs between moral agency, peek experience and novelty.
