    Sure. But I just did a search on the Kindle sample and notice the term ‘idealism’ does not appear. All the examples in that sample are taken from biology. It’s possible those like myself with a previous interest in philosophical idealism are reading things into it that aren’t there.

    Thanks! I do see his point, it’s more or less the same objection I raised at the very beginning. It’s like when David Stove would compare positivism to the Uroboros, the snake that eats itself - ‘the hardest part’, he would say with a mischievous grin, ‘is the last bite.’

    That said, I’m still not dismissing Hoffman out of hand. I’ll try and finish more of the book.

    Where or what is Tallis’ criticism of Hoffman that you keep alluding to?
  • Donald Trump (All General Trump Conversations Here)
    Trump’s continued attacks on the Department of Justice and the judiciary are another assault on the democratic state, aided and abetted (although clumsily) by his congressional sock-puppets. I think he should be held in contempt of court - as he so obviously does hold courts in contempt - and threatened with a custodial sentence if he keeps it up. He is after all arraigned in a criminal case, and should be treated like any other defendant who attacks the Court whilst subject to its jurisdiction.

    Neo-darwinian materialism surely does. But it has many critics, not least Raymond Talllis:

    Broadly speaking, Aping Mankind is about sloppy science. That is, it’s an attack on scientism, the mistaken belief that all important questions are best tackled with the use of natural science techniques. It’s about how hubris can cause as prestigious a subject as science to overestimate and overextend itself. More specifically, Aping Mankind is about the impact of this tendency on biological theories of human mental development, with all the philosophical mind/body issues which that involves. Raymond Tallis delivers a heartfelt polemic against what he sees as a great many errors and unproven assumptions, which are wide-ranging and yet interlinked. What holds these assumptions together is a blind adherence to what seems to be the most scientifically-convenient – though not necessarily correct – philosophy, a form of what is called ‘materialism’. In the process Tallis trains his guns on an array of notables, such as John Gray, Daniel Dennett and Susan Blackmore. As ammunition he has coined some new words, for example, those used in the book’s subtitle, ‘neuromania’ and ‘darwinitis’.

    I have that book, later I’ll see if Hoffman is mentioned, although I don’t recall.

    The core of realism, probably also to no avail, but for comparison, is simply that there are statements that are true, yet not known or even believed.

    Things such as those we haven't found out yet, or are mistaken about.

    That is, there is a world that is not dependent on our understanding of it.

    Idealism is not a claim to omniscience.

    I submit that the only need to make sense of appearances being deceptive, is if they are mistakenly treated as “looks like” as opposed to the intended notion of “present as”.Mww

    In Greek philosophy there is the notion that we can't say what any thing 'truly is', because it is not 'truly' any specific thing. This is suggested by the argument from equality in Phaedo 72e ff:


      [1] We perceive sensible objects to be F.
      [2] But every sensible object is, at best, imperfectly F. That is, it is both F and not F. It falls short of being truly F.
      [3 ] We are aware of this imperfection in the objects of perception.
      [4] So we perceive objects to be imperfectly F.
      [5] To perceive something as imperfectly F, one must already have in mind something that is perfectly F, something that the imperfectly F things fall short of. (e.g, we have an idea of equality that all sticks, stones, etc., only imperfectly exemplify.)
      [6] So we have in mind something that is perfectly F.
      [7] Thus, there is something that is perfectly F (e.g. equality), that we have in mind in such cases.
      [8] Therefore, there is such a thing as the F itself (e.g., the Equal itself), and it is distinct from any sensible object.
    .

    (I'm sure there are other examples of this point but my knowledge of Greek philosophy is not great.)

    But one of the problems is, the discussion nearly always defaults back to whether coffee cups or trees or whatever kind of 'F' are real. We loose sight of the fact that the object chosen merely serves to symbolise objective knowledge, more broadly. So what I think is really at stake is 'seeing how things truly are' in an expansive sense. The philosophically discerning mind realises its own judgement is central to the generally taken-for-granted nature of the sensory domain (as in the example above). 'The sage' as a philosophical archetype, one who'sees things as they truly are' not in the narrow sense required by the precise sciences, but as a general grasp or insight into the imperfection of our sensory knowledge. So it is precisely the opposite to a claim of omniscience - it is an acknowledgement of the limitations of empiricism.

  • The nature of mistakes.
    A couple of years ago, I rebuilt the deck on our home. It was a large deck, and my carpentry skills are rudimentary, so I made many a mistake - some easily rectified, some undo-able. I ruefully reflected on the fact that apprenticeship largely comprises a long series of supervised mistakes - that the apprentice, supervised by a master, gets the chance to make mistakes in a controlled kind of way, and as a consequence becomes skilled over time. Whereas the home handy-man, committed to a large job of this kind, has no such luxury, and has to live with whatever mistakes he made. (Turned out alright, but I knew where all the errors were.)

  • [Ontology] Donald Hoffman’s denial of materialism
    I think the basic issue comes down to whether objects of experience possess intrinsic reality. This kind of critical analysis is characteristic of Tibetan Buddhist philosophy, arising from their principle of sunyata and dependent origination. It grants that objects of experience are real, but that their reality is dependent on causes and conditions, and not inherent or intrinsic to them; they are not real 'from their own side' is one way that it is put.

    However, Buddhists also make use of the so-called 'two truths' doctrine. This is says that there are two levels of reality, the conventional/empirical (samvritti) and the ultimate (paramatha). On the conventional level, empiricism is the arbiter, even if from the level of ultimate truth the objects of experience are devoid of intrinsic reality (although there is often considerable scholastic analysis involved in the details.)

    Murti's book Central Philosophy of Buddhism compared the 'two truths' doctrine with Kant's acknowledgment that one can be at once an empirical realist, and a transcendental idealist, as expressed in these two often-quoted paragraphs.

    I understand by thetranscendental idealism of all appearances the doctrine that they are all together to be regarded as mere representations and not things in themselves, and accordingly that space and time are only sensible forms of our intuition, but not determinations given for themselves or conditions of objects as things in themselves. To this idealism is opposed transcendental realism, which regards space and time as something given in themselves (independent of our sensiblity). The transcendental realist therefore represents outer appearances (if their reality is conceded) as things in themselves, which would exist independently of us and our sensibility and thus would also be outside us according to pure concepts of the understanding.

    The transcendental idealist, on the contrary, can be an empirical realist, hence, as he is called, a dualist, i.e., he can concede the existence of matter without going beyond mere self-consciousness and assuming something more than the certainty of representations in me, hence the cogito ergo sum. For because he allows this matter and even its inner possibility to be valid only for appearance– which, separated from our sensibility, is nothing –matter for him is only a species of representations (intuition), which are call external, not as if they related to objects that are external in themselves but because they relate perceptions to space, where all things are external to one another, but that space itself is in us.
    — (CPR, A369, 379)

    The reason I mention this, is because it provides a kind of conceptual background for making sense of the claim that appearances are deceptive.
  • Ontological arguments for idealism
    When one introspects upon their experience (which is consciousness), they will begin to realize that every object within their experience is wholly reducible to a collection of sensations.Bob Ross

    How about judgement and reason? Is a rational judgement, like a syllogism, reducible to sensations?

    However, the typical definition of ontological idealism is that it is the view that all of reality consists solely of the mental.Ø implies everything

    I think there's an unstated problem in this description, which is how to grasp 'the mental' as an object of cognition. I think this is what panpsychism does: it attempts to show that the capacity for experience is something which even the most primitive fundamental particles, such as electrons, possess, and is in that sense, an objectively existent attribute. Then this latent capacity for experience is said to account for the much more sophisticated capacities found in animals and humans.

    However, panpsychism is criticized for the combination problem, i.e. what is it that enables all these micro-experiential entities to be combined into the unified whole that presents itself in experience. Many philosophers regard that as a defeater for the Strawson/Goff style of panpsychism.

  • Where do thoughts come from? Are they eternal? Does the Mindscape really exist?
    Fair enough. Don't mind chewing over it, all grist to the mill.
  • Where do thoughts come from? Are they eternal? Does the Mindscape really exist?
    why worry?Jamal

    Thomists and other critics of Ockham have tended to present traditional [i.e. 'scholastic'] realism with its forms or natures, as the solution to the modern problem of knowledge. It seems to me that it does not quite get to the heart of the matter. A genuine realist should see “forms” not merely as a solution to a distinctly modern problem of knowledge, but as part of an alternative conception of knowledge, a conception that is not so much desired and awaiting defense, as forgotten and so no longer desired. Characterized by forms, reality had an intrinsic intelligibility, not just in each of its parts but as a whole. With forms as causes, there are interconnections between different parts of an intelligible world, indeed there are overlapping matrices of intelligibility in the world, making possible an ascent from the more particular, posterior, and mundane to the more universal, primary, and noble.

    In short, the appeal to forms or natures does not just help account for the possibility of trustworthy access to facts, it makes possible a notion of wisdom, traditionally conceived as an ordering grasp of reality.

  • Where do thoughts come from? Are they eternal? Does the Mindscape really exist?
    I agree that we can discursively break the world up and think about the category or concept of a dog as apart from any particular dog. We indeed have that sort of metacognition.green flag

    Which is the basis of the Theory of Forms.

    I actually tracked down the source of this intuition I had about the Greeks and the ontological status of number:

    Neoplatonic mathematics is governed by a fundamental distiction which is indeed inherent in Greek science in general, but is here most strongly formulated. According to this distinction, one branch of mathematics participates in the contemplation of that which is in no way subject to change, or to becoming and passing away. This branch contemplates that which is always such as it is and which alone is capable of being known: for that which is known in the act of knowing, being a communicable and teachable possession, must be something that is once and for all fixed. — Jacob Klein, Greek Mathematical Thought and the Origin of Algebra.

    When I experienced the 'aha' moment about why the ancients thought that maths was of a different order of reality to sensory objects, this is more or less all I saw. Subsequently I've pursued the theme as it developed, and then more or less petered out in the late medieval period (save for the remaining mathematical platonists, of whom there are always some.)
  • Where do thoughts come from? Are they eternal? Does the Mindscape really exist?
    I wouldn't even say they are so different.green flag

    There is a difference between phenomenal objects which are temporally delimited and composed of parts, and those objects of thought which are not. Which is a distinction that I think is basic theme of Greek philosophy, between sensible and rational. Doesn't mean a dichotomy or a conflict, but a distinction.
  • Where do thoughts come from? Are they eternal? Does the Mindscape really exist?
    It's also hard to make sense of the claim that only such objects exist,green flag

    This argument came out of my attempt to show that ‘existence’ pertains to phenomenal objects, and that intelligible objects, like number, exist in a different way to phenomenal objects, in that they can only be grasped by rational thought, not by the senses. Russell uses the term ‘to subsist’ in distinction from ‘to exist’. They are, in the pre-Kantian sense, ‘noumenal’, meaning, ‘objects of nous’. (I say pre-Kantian because Kant appropriated the term ‘noumenal’ for another purpose.) I think that distinction can be mapped against hylomorphism, but that since the abandonment of scholastic realism concerning metaphysics, it is a distinction which has become lost in the modern lexicon. So I’m not saying that they’re non-existent, but that they’re real in a different sense to phenomenal objects.

    (This is also related to the negative theology of Paul Tillich, for anyone familiar.)
  • The difference between religion and faith
    Stevenson is a hot-button issue. Shouldn't have brought it up, and won't do so again on this forum, as so many people find it upsetting.
  • The Being of Meaning
    There is, I mean, no aboriginal stuff or quality of being, contrasted with that of which material objects are made, out of which our thoughts of them are made; but there is a function in experience which thoughts perform, and for the performance of which this quality of being is invoked. That function is knowing. — William James

    :100: Notice how this re-affirms my criticism of Descartes' reification - because that is what it is - of the self as 'res cogitans', which is what subsequently gave rise to Ryle's 'ghost in the machine' argument.

  • The difference between religion and faith
    It seems you have studied the evidence Stevenson produced more than I.universeness

    Which I presume is 'not at all'.

    Again: the reason I brought up Stevenson's research was in respect of the claim that there is 'no public evidence' concerning past-life beliefs. All I have read about him (apart from online) is a documentary account of Stevenson's life and research by a journalist who travelled with him, Old Souls, by Tom Schroder, and one of Stevenson's books, which I borrowed from the library. He presents a lot of documentary evidence in that book - each case was thoroughly investigated, with questionnaires, document searches, witness with interviews, and so on. Believe it, don't believe, it doesn't bother me, but you can't say 'there's no published evidence'. That is the only point I'm making.
  • The Being of Meaning
    What idealists 'want to say' (but don't manage to say) is roughly correct. That's my claim.green flag

    Or maybe they do manage to say it, but you don't get it. I say 'occult' is deliberately pejorative, in this context. Ryle's ghost metaphor is grounded in the fundamental flaw of Cartesianism, which is the 'objectification of the self' - treating the self as a kind of ghostly thinking thing. The right stance is that 'the eye can't see itself, the hand can't grasp itself' - the self is elusive, not because it's ghostly or occult, but it is not in the objective frame, it's the subject of experience, not the object of knowledge. Since Descartes, western philosophy has never been able to deal with that, hence the Cartesian anxiety - referring to the notion that, 'since René Descartes posited his influential form of body-mind dualism, Western civilization has suffered from a longing for certainty, or feeling that scientific methods, and especially the study of the world as a thing separate from ourselves, should be able to lead us to a firm and unchanging knowledge of ourselves and the world around us. The term is named after Descartes because of his well-known emphasis on "mind" as different from "body", "self" as different from "other"'. Richard J. Bernstein coined the term in his 1983 book Beyond Objectivism and Relativism: Science, Hermeneutics, and Praxis. You can see how the dismissive use of the term 'occult' is used in a futile attempt to combat that anxiety - by depicting it in terms usually reserved for side-show charlatans and fortune tellers. Speaks volumes.
  • Where do thoughts come from? Are they eternal? Does the Mindscape really exist?
    And do you accept his classification, wherein ideas do exist, and it's only universals that don't?Jamal

    I am saying that existence properly refers to phenomenal objects. But that is not ‘privileging’ them. What Russell is articulating is a distinction in modes of being - between things that exist in time and space, and universals, which subsist. It’s an awkward distinction, I agree.

    Here’s a really obscure reference, to the philosophical theology of Scotus Eriugena, but it’s about the only place that actually articulates what I’m driving at https://plato.stanford.edu/entries/scottus-eriugena/#FiveModeBeinNonBein
  • Where do thoughts come from? Are they eternal? Does the Mindscape really exist?
    But another way of paying attention to the differentiation is to say that something exists in a different way.Jamal

    I agree - that's what I'm trying to say. What Russell says is:

    We shall find it convenient only to speak of things existing when they are in time, that is to say, when we can point to some time at which they exist (not excluding the possibility of their existing at all times). Thus thoughts and feelings, minds and physical objects exist. But universals do not exist in this sense; we shall say that they subsist or have being, where 'being' is opposed to 'existence' as being timeless. — Bertrand Russell

    Also note this from an IEP article:

    In contrast to contemporary philosophers, most 17th century philosophers (i.e. Spinoza, Leibniz, Descartes) held that reality comes in degrees—that some things that exist are more or less real than other things that exist. At least part of what dictates a being’s reality, according to these philosophers, is the extent to which its existence is dependent on other things: the less dependent a thing is on other things for its existence, the more real it is.

    Whereas, what I'm arguing is that I think the very idea of there being 'degrees of reality' is no longer intelligible. So there are no 'different ways' in which things can exist - we say that things either exist, or they don't. Tables and chairs exist, unicorns and the square root of 2 do not. Whereas, I'm saying, intelligible objects, such as numbers, are real, as constituents of reason, but not existent, as phenomenal objects. So that re-introduces a distinction I think has been lost.
  • Where do thoughts come from? Are they eternal? Does the Mindscape really exist?
    What have you got against the use of “exist” for ideas, numbers, etc.?Jamal

    I noticed that something that is characteristic of phenomenal objects is that they are temporally delimited - they come into and go out of existence - and they are composed of parts. Numbers - well, prime number, but anyway - don't come into and go out of existence, and are not composed of parts.
    They can be described in terms of of Frege's 'third realm' - the realm of abstract objects such as numbers, sets, and functions. He believed that these abstract objects existed independently of the physical world and the mind, and that they had a different kind of reality that was not reducible to either physical or mental phenomena.

    According to Frege, this third realm was a necessary foundation for mathematics, which he saw as a discipline concerned with the study of these abstract objects. He argued that mathematical concepts such as "2+2=4" were not simply facts about physical objects or mental states, but were instead true in virtue of the abstract objects they referred to. It is generally regarded as platonist, although Frege did not really articulate it in those terms, it more that he simply assumed it to be true. (See Tyler Burge, Frege on Knowing the Third Realm.)

    it looks like you’re downgrading numbers just because they’re not objects of physical science.Jamal

    Not at all. I believe that numbers, principles, natural laws, and the like, belong to a different realm to the phenomenal domain, but that generally modern philosophy has lost sight of this differentiation. As Russell points out in the chapter I referred to above about universals, they exist 'no-where and no-when', but they're real nevertheless. But I think that's the gist of Platonic epistemology, as outlined in the Analogy of the Divided Line in the Republic. As a consequence, we tend to think that what is real, and what exists, are synonymous, but I'm arguing that what exists is only one aspect of what is real.

    I get that it's a form of metaphysics, and I also get that this style of metaphysics is very unpopular, but it interests me.
  • Where do thoughts come from? Are they eternal? Does the Mindscape really exist?
    So, in my view, I directly experience sensations: i.e., the five physical senses, emotions, and thoughts. Everything else is an idea that makes sense of my perceptions.Art48

    I don't question any of that. However, you also interpret meanings, which is why you are able to communicate in writing. That is not something reducible to sensations.

    What is an "arithmetical fact"? That we use a human invented symbolism like "2+2=4" and that this has rules of use, and has application in our world. OK. Or, do you mean "2+2=4" is a fact because it corresponds to some eternal idea.Richard B

    I think the way you're putting it somewhat reifies it. What I mean by 'all possible worlds' is simply that basic arithmetical propositions such as those we're discussing, are necessarily true. I understand Wittgenstein, Austin and the ordinary language philosophers are averse to metaphysics, but I don't share their aversion. In any case, I'm of the view that at least some of the fundamental elements of arithmetic and logic are not the inventions of humans, but are discovered by humans who have developed the intelligence to be able to grasp them. Conversely, I don't believe that the basic furniture of reason is dependent on the human mind or are simply conventions. Yes, this has metaphysical implications, but that's what interests me. I'm interested in the history of the subject, and of how scholastic realism regarding universals was displaced by nominalism and eventually by today's empiricism.

    What make "arithmetical facts" true?Richard B

    Well, a vulgar example is, get your maths wrong, and your bridge will collapse or your rocket will blow up at launch. And so on. But that's applied mathematics. What makes basic arithmetical operations true is kind of a redundant question - I don't know if it can be explained. Mathematics after all is the source of the explanation of many other things, but asking why it's true, is rather like asking why two and two are four, which doesn't have an answer. Or, to the question, what does two plus two equal, the answer 'four' is the terminus of explanation, as it were.

    What I'm interested in exploring is the ontology of number, as I've indicated. And I'm also interested in Wigner's 'unreasonable efficacy of mathematics in the natural sciences'. I think it says something interesting.

  • [Ontology] Donald Hoffman’s denial of materialism
    :up: Glad you get it!

    I emailed Tallis once, and he replied.



    Some notes on the support cognitive science lends to views once understood as idealist.

    First, it has shown that our perceptions of the world are not passive reflections of an objective reality, but rather active constructions generated by our brains. Our sensory experiences are shaped by our cognitive processes, such as attention, memory, and expectation, which are themselves shaped by our beliefs, values, and cultural background. This suggests that our experience of the world is not a direct representation of a mind-independent reality, but that there subjective elements are fundamental to our consciousness of it. Furthermore, these subjective elements are not themselves directly available in experience (they're transcendental in the Kantian sense.)

    Second, cognitive science has shown that our mental states, such as beliefs, desires, and emotions, are not simply epiphenomenal byproducts of physical processes, but rather causally effective in shaping our behavior and experience. This suggests that mental states have an ontological status that irreducible to purely physical phenomena (which is the hard problem, again.)

    Finally, 'embodied cognition' or 'enactivism', an approach within cog sci, reveals the profound interdependence of the mind and the environment. This suggests that the boundaries between the mind and the world are not fixed, but rather fluid and context-dependent. As Buddhists might put it, that the subjective and the objective are 'co-arising'.

    Taken together, these insights from cognitive science support a view of reality as fundamentally grounded in mental states, insofar as they challenge the traditional Cartesian dualism between mind and matter, and also emphasize the role of subjective interpretation and embodiment in shaping our experience of the world.

    Whether that amounts to an idealist philosophy in the Berkeleyian sense is moot, but there is a scholar called Andrew Brook who's made an academic career on Kant and cognitive science. You can find some of his articles on SEP.
  • [Ontology] Donald Hoffman’s denial of materialism
    In support of what I think @Manuel is saying, and in response to @Banno's realist objections. I've quoted this about umpteen times previously, but I'll give it another shot (probably to no avail)

    'Everyone knows that the earth, and a fortiori the universe, existed for a long time before there were any living beings, and therefore any perceiving subjects. But according to Kant ... that is impossible.'

    Schopenhauer's defence of Kant on this score was [that] the objector has not understood to the very bottom the Kantian demonstration that time is one of the forms of our sensibility. The earth, say, as it was before there was life, is a field of empirical enquiry in which we have come to know a great deal; its reality is no more being denied than is the reality of perceived objects in the same room.

    The point is, the whole of the empirical world in space and time is the creation of our understanding, which apprehends all the objects of empirical knowledge within it as being in some part of that space and at some part of that time: and this is as true of the earth before there was life as it is of the pen I am now holding a few inches in front of my face and seeing slightly out of focus as it moves across the paper.

    This, incidentally, illustrates a difficulty in the way of understanding which transcendental idealism has permanently to contend with: the assumptions of 'the inborn realism which arises from the original disposition of the intellect' enter unawares into the way in which the statements of transcendental idealism are understood.

    Such realistic assumptions so pervade our normal use of concepts that the claims of transcendental idealism disclose their own non-absurdity only after difficult consideration, whereas criticisms of them at first appear cogent which on examination are seen to rest on confusion. We have to raise almost impossibly deep levels of presupposition in our own thinking and imagination to the level of self-consciousness before we are able to achieve a critical awareness of all our realistic assumptions, and thus achieve an understanding of transcendental idealism which is untainted by them.
