| 13734 | Modern Quinean metaphysics is about what exists, but Aristotelian metaphysics asks about grounding [Schaffer,J] |
| Full Idea: On the now dominant Quinean view, metaphysics is about what there is (such as properties, meanings and numbers). I will argue for the revival of a more traditional Aristotelian view, on which metaphysics is about what grounds what. | |
| From: Jonathan Schaffer (On What Grounds What [2009], Intro) | |
| A reaction: I find that an enormously helpful distinction, and support the Aristotelian view. Schaffer's general line is that what exists is fairly uncontroversial and dull, but the interesting truths about the world emerge when we grasp its structure. |
| 13751 | If you tore the metaphysics out of philosophy, the whole enterprise would collapse [Schaffer,J] |
| Full Idea: Traditional metaphysics is so tightly woven into the fabric of philosophy that it cannot be torn out without the whole tapestry unravelling. | |
| From: Jonathan Schaffer (On What Grounds What [2009], 2.3) | |
| A reaction: I often wonder why the opponents of metaphysics still continue to do philosophy. I don't see how you address questions of ethics, or philosophy of mathematics (etc) without coming up against highly general and abstract over-questions. |
| 7113 | Phenomenology assumes that all consciousness is of something [Sartre] |
| Full Idea: The essential principle of phenomenology is that 'all consciousness is consciousness of something'. | |
| From: Jean-Paul Sartre (Transcendence of the Ego [1937], I (B)) | |
| A reaction: This idea is found well before Husserl, in Schopenhauer (Idea 4166). It seems to contradict a thought such as Locke's (Idea 1202), that self-awareness is a separate and distinct criterion for personal identity. Sartre gives a nice account. |
| 13743 | We should not multiply basic entities, but we can have as many derivative entities as we like [Schaffer,J] |
| Full Idea: Occam's Razor should only be understood to concern substances: do not multiply basic entities without necessity. There is no problem with the multiplication of derivative entities - they are an 'ontological free lunch'. | |
| From: Jonathan Schaffer (On What Grounds What [2009], 2.1) | |
| A reaction: The phrase 'ontological free lunch' comes from Armstrong. This is probably what Occam meant. A few extra specks of dust, or even a few more numbers (thank you, Cantor!) don't seem to challenge the principle. |
| 13741 | If 'there are red roses' implies 'there are roses', then 'there are prime numbers' implies 'there are numbers' [Schaffer,J] |
| Full Idea: We can automatically infer 'there are roses' from 'there are red roses' (with no shift in the meaning of 'roses'). Likewise one can automatically infer 'there are numbers' from 'there are prime numbers'. | |
| From: Jonathan Schaffer (On What Grounds What [2009], 2.1) | |
| A reaction: He similarly observes that the atheist's 'God is a fictional character' implies 'there are fictional characters'. Schaffer is not committing to a strong platonism with his claim - merely that the existence of numbers is hardly worth disputing. |
| 13748 | Grounding is unanalysable and primitive, and is the basic structuring concept in metaphysics [Schaffer,J] |
| Full Idea: Grounding should be taken as primitive, as per the neo-Aristotelian approach. Grounding is an unanalyzable but needed notion - it is the primitive structuring conception of metaphysics. | |
| From: Jonathan Schaffer (On What Grounds What [2009], 2.2) | |
| A reaction: [he cites K.Fine 1991] I find that this simple claim clarifies the discussions of Kit Fine, where you are not always quite sure what the game is. I agree fully with it. It makes metaphysics interesting, where cataloguing entities is boring. |
| 13747 | Supervenience is just modal correlation [Schaffer,J] |
| Full Idea: Supervenience is mere modal correlation. | |
| From: Jonathan Schaffer (On What Grounds What [2009], 2.2) |
| 13744 | The cosmos is the only fundamental entity, from which all else exists by abstraction [Schaffer,J] |
| Full Idea: My preferred view is that there is only one fundamental entity - the whole concrete cosmos - from which all else exists by abstraction. | |
| From: Jonathan Schaffer (On What Grounds What [2009], 2.1) | |
| A reaction: This looks to me like weak anti-realism - that there are no natural 'joints' in nature - but I don't think Schaffer intends that. I take the joints to be fundamentals, which necessitates that the cosmos has parts. His 'abstraction' is clearly a process. |
| 13739 | Maybe categories are just the different ways that things depend on basic substances [Schaffer,J] |
| Full Idea: Maybe the categories are determined by the different grounding relations, ..so that categories just are the ways things depend on substances. ...Categories are places in the dependence ordering. | |
| From: Jonathan Schaffer (On What Grounds What [2009], 1.3) |
| 22320 | An 'object' is just what can be referred to without possible non-existence [Wittgenstein] |
| Full Idea: What I once called 'objects', simples, were simply what I could refer to without running the risk of their possible non-existence. | |
| From: Ludwig Wittgenstein (Philosophical Remarks [1930], p.72), quoted by Michael Potter - The Rise of Analytic Philosophy 1879-1930 52 'Simp' | |
| A reaction: For most of us, you can refer to something because you take it to be an object. For these Fregean influenced guys (e.g. Hale) something is an object because you can refer to it. Why don't they use 'object*' for their things? |
| 13742 | There exist heaps with no integral unity, so we should accept arbitrary composites in the same way [Schaffer,J] |
| Full Idea: I am happy to accept universal composition, on the grounds that there are heaps, piles etc with no integral unity, and that arbitrary composites are no less unified than heaps. | |
| From: Jonathan Schaffer (On What Grounds What [2009], 2.1 n11) | |
| A reaction: The metaphysical focus is then placed on what constitutes 'integral unity', which is precisely the question which most interested Aristotle. Clearly if there is nothing more to an entity than its components, scattering them isn't destruction. |
| 13752 | The notion of 'grounding' can explain integrated wholes in a way that mere aggregates can't [Schaffer,J] |
| Full Idea: The notion of grounding my capture a crucial mereological distinction (missing from classical mereology) between an integrated whole with genuine unity, and a mere aggregate. x is an integrated whole if it grounds its proper parts. | |
| From: Jonathan Schaffer (On What Grounds What [2009], 3.1) | |
| A reaction: That gives a nice theoretical notion, but if you remove each of the proper parts, does x remain? Is it a bare particular? I take it that it will have to be an abstract principle, the one Aristotle was aiming at with his notion of 'form'. Schaffer agrees. |
| 13749 | Belief in impossible worlds may require dialetheism [Schaffer,J] |
| Full Idea: One motivation for dialetheism is the view that there are impossible worlds. | |
| From: Jonathan Schaffer (On What Grounds What [2009], 2.3) |
| 13740 | 'Moorean certainties' are more credible than any sceptical argument [Schaffer,J] |
| Full Idea: A 'Moorean certainty' is when something is more credible than any philosopher's argument to the contrary. | |
| From: Jonathan Schaffer (On What Grounds What [2009], 2.1) | |
| A reaction: The reference is to G.E. Moore's famous claim that the existence of his hand is more certain than standard sceptical arguments. It sounds empiricist, but they might be parallel rational truths, of basic logic or arithmetic. |
| 7112 | The Cogito depends on a second-order experience, of being conscious of consciousness [Sartre] |
| Full Idea: We must remember that all authors who have described the Cogito have presented it as a reflective operation, i.e. as second-order. This Cogito is performed by a consciousness directed towards consciousness, which takes consciousness as its object. | |
| From: Jean-Paul Sartre (Transcendence of the Ego [1937], I (B)) | |
| A reaction: Sartre is raising the nice question of whether the Cogito still works for first-order consciousness, which attends totally to external objects. He claims that it doesn't. Contrast Russell, who says (Idea 5380) that it only works when it is first-order! |
| 7114 | The consciousness that says 'I think' is not the consciousness that thinks [Sartre] |
| Full Idea: The consciousness that says 'I think' is precisely not the consciousness that thinks. | |
| From: Jean-Paul Sartre (Transcendence of the Ego [1937], I (B)) | |
| A reaction: All parties seem to be agreed that if we are going to introspect in search of our own ego, we must distinguish between the mental act of instrospection and the mental act of applying the mind to the world. Each gives a different result. |
| 7119 | Is the Cogito reporting an immediate experience of doubting, or the whole enterprise of doubting? [Sartre] |
| Full Idea: When Descartes says 'I doubt therefore I am', is he talking about the spontaneous doubt that reflective consciousness grasps in its instantaneous character, or is he talking of the enterprise of doubting? This ambiguity can lead to serious errors. | |
| From: Jean-Paul Sartre (Transcendence of the Ego [1937], II (B)) | |
| A reaction: Interesting. The obvious response is that it is about the immediate experience, but that leads to the problem of an instantaneous ego, which can't be justified over time. The 'enterprise' gives an enduring ego, but it is a more intellectual concept. |
| 7122 | We can never, even in principle, grasp other minds, because the Ego is self-conceiving [Sartre] |
| Full Idea: The Ego can be conceived only through itself and this is why we cannot grasp the consciousness of another (for this reason alone, and not because bodies separate us). | |
| From: Jean-Paul Sartre (Transcendence of the Ego [1937], II (D)) | |
| A reaction: Interesting. This makes telepathy a logical impossibility, and the body the only possible route for the communication between two minds. But, is Sartre is right, how do bodily events penetrate the inturned world of the Ego? |
| 7125 | A consciousness can conceive of no other consciousness than itself [Sartre] |
| Full Idea: A consciousness can conceive of no other consciousness than itself. | |
| From: Jean-Paul Sartre (Transcendence of the Ego [1937], Conc (1)) | |
| A reaction: This is why we don't know what it is like to be a bat. This seems right, though it looks like a contingent truth, and yet Sartre seems to offer it as a necessary truth. Can God conceive of my consciousness? |
| 7108 | The eternal truth of 2+2=4 is what gives unity to the mind which regularly thinks it [Sartre] |
| Full Idea: The unity of the thousand active consciousnesses through which I have added two and two to make four, is the transcendent object '2+2=4'. Without the permanence of this eternal truth, it would be impossible to conceive of a real unity of mind. | |
| From: Jean-Paul Sartre (Transcendence of the Ego [1937], I (A)) | |
| A reaction: This is the germ of externalism, here presented as a Platonic attitude to arithmetic, rather than being about water or gold. He claims that internalist attitudes to unity are fictions. I am inclined to think he is wrong, and that unity is biological. |
| 7111 | Consciousness exists as consciousness of itself [Sartre] |
| Full Idea: The existence of consciousness is an absolute, because consciousness is consciousness of itself; the type of existence that consciousness has is that it is consciousness of itself. | |
| From: Jean-Paul Sartre (Transcendence of the Ego [1937], I (A)) | |
| A reaction: I find this unconvincing. Anyone analysis the nature of the mind should think as much about animal minds as human minds. It seems obvious to me that there is likely to be an animal consciousness which is entirely of environment and its body. |
| 22226 | Since we are a consciousness, Sartre entirely rejected the unconscious mind [Sartre, by Daigle] |
| Full Idea: Sartre refused, denied and fought against the unconscious. Since we are consciousness, there cannot be such a thing as unconsciousness. | |
| From: report of Jean-Paul Sartre (Transcendence of the Ego [1937]) by Christine Daigle - Jean-Paul Sartre 2.1 | |
| A reaction: The modern view is increasingly opposed to this, as neuroscience and psychology uncover hidden motives etc. Sartre's view is still legitimate, though. An unconscious motive is not more my motive than a law of the land is part of me? |
| 7107 | Intentionality defines, transcends and unites consciousness [Sartre] |
| Full Idea: Consciousness is defined by intentionality. Through intentionality it transcends itself, it unifies itself by going outside itself. | |
| From: Jean-Paul Sartre (Transcendence of the Ego [1937], I (A)) | |
| A reaction: The standard view for a hundred years was Brentano's idea that intentionality defines the mind. Qualia are the modern rival. If I had to choose I think I would go for intentionality, but they may be naturally and metaphysically inseparable. |
| 7109 | If you think of '2+2=4' as the content of thought, the self must be united transcendentally [Sartre] |
| Full Idea: It is possible that those who think that '2 and 2 make 4' is the content of my representations may be forced to resort to a transcendental and subjective principle of unification - in other words, the I. | |
| From: Jean-Paul Sartre (Transcendence of the Ego [1937], I (A)) | |
| A reaction: He suggests that thoughts themselves unite the mind, externally. If you think of thoughts as internal, you must resort to a transcendental fiction to unify the mind. Personally I think the mind is inherently unified by brain structures. |
| 7106 | The Ego is not formally or materially part of consciousness, but is outside in the world [Sartre] |
| Full Idea: I should like to show here that the Ego is neither formally nor materially in consciousness; it is outside, in the world; it is a being in the world, like the Ego of another. | |
| From: Jean-Paul Sartre (Transcendence of the Ego [1937], Intro) | |
| A reaction: This idea is the germ of what has got modern externalists about the mind (see quotations from Mark Rowlands) interested in Sartre. Personally I think he is wrong, and the Ego is a part of consciousness. It doesn't, though, have sharp boundaries. |
| 7117 | How could two I's, the reflective and the reflected, communicate with each other? [Sartre] |
| Full Idea: If the 'I' is part of consciousness, there will be two I's: the reflective and the reflected. ...but it is unacceptable for any communication to be established between the reflective I and the reflected I, if they are real elements of consciousness. | |
| From: Jean-Paul Sartre (Transcendence of the Ego [1937], I (B)) | |
| A reaction: If we accept that there are two orders of consciousness (reflective, about itself, and reflected, about the world) it seems reasonable to say that there cannot be an 'I' in both of them. A nice, and intriguing, argument. |
| 7123 | Knowing yourself requires an exterior viewpoint, which is necessarily false [Sartre] |
| Full Idea: 'To know oneself well' is inevitably to look at oneself from the point of view of someone else, in other words from a point of view that is necessarily false. | |
| From: Jean-Paul Sartre (Transcendence of the Ego [1937], II (D)) | |
| A reaction: (This is because the Ego cannot be known from the outside). I agree with Russell that the self is most evident when we are engaged with the world, which implies that you can only acquire self-knowledge by studying those engagements. |
| 22225 | My ego is more intimate to me, but not more certain than other egos [Sartre] |
| Full Idea: My I, in efffect, is no more certain for consciousness than the I of other men. It is only more intimate. | |
| From: Jean-Paul Sartre (Transcendence of the Ego [1937], p.104), quoted by Christine Daigle - Jean-Paul Sartre 2.1 | |
| A reaction: Not sure how to assess this. Other people seem just as real as I do, when I encounter them, as friend or as foe. And in dealing with them we act as if dealing with their Self (rather than their legs, say). So this idea seems a good one. |
| 7124 | The Ego never appears except when we are not looking for it [Sartre] |
| Full Idea: The Ego never appears except when we are not looking for it. | |
| From: Jean-Paul Sartre (Transcendence of the Ego [1937], II (D)) | |
| A reaction: He denies that we know the Ego when engaged with the world, and agrees with Hume that the ego can't be directly known. All that is left is this, which seems to be introspection 'out of the corner of your eye'. Not persuasive. |
| 7116 | When we are unreflective (as when chasing a tram) there is no 'I' [Sartre] |
| Full Idea: There is no 'I' on the unreflected level. When I run after a tram, ...there is no I. There is a consciousness of the tram-needing-to-be-caught, and a non-positional consciousness of consciousness. | |
| From: Jean-Paul Sartre (Transcendence of the Ego [1937], I (B)) | |
| A reaction: Russell (Idea 5380) says exactly the opposite. My sympathies are more with Russell. I don't just focus on the tram, I focus on the relation between myself and the tram, and that includes my need to catch it, as well as my body. |
| 7120 | It is theoretically possible that the Ego consists entirely of false memories [Sartre] |
| Full Idea: One cannot rule out the metaphysical hypothesis that my Ego is not composed of elements that have existed in reality (ten years or one second ago), but is merely constituted by false memories. | |
| From: Jean-Paul Sartre (Transcendence of the Ego [1937], II (D)) | |
| A reaction: (He mentions the evil demon as a source). The problem that false memories (such as George IV 'remembering' he was at Waterloo, when he wasn't) is well known. But this raises the possibility of all memories being false, yet constituting the person. |
| 7110 | If the 'I' is transcendental, it unnecessarily splits consciousness in two [Sartre] |
| Full Idea: The superfluous transcendental 'I' is actually a hindrance. If it existed, it would violently separate consciousness from itself, it would divide it, slicing through consciousness like an opaque blade. | |
| From: Jean-Paul Sartre (Transcendence of the Ego [1937], I (A)) | |
| A reaction: I see no a priori reason why consciousness should not be split in two, if that's how it is. Personally I am happy with a fairly traditional Cartesian view, that the self is the will and understanding, and the rest of consciousness is its working material. |
| 7115 | Maybe it is the act of reflection that brings 'me' into existence [Sartre] |
| Full Idea: Might it not be precisely the reflective act that brings the me into being in reflected consciousness? | |
| From: Jean-Paul Sartre (Transcendence of the Ego [1937], I (B)) | |
| A reaction: He admits some sort of self a second-order entity, but this is 'transcendental', and essentially an illusion. This elimination of the first-order self clears the way for the existential view, that we can create whatever self we want. I disagree. |
| 7121 | The Ego only appears to reflection, so it is cut off from the World [Sartre] |
| Full Idea: The Ego is an object that appears only to reflection, and is thereby radically cut off from the World. | |
| From: Jean-Paul Sartre (Transcendence of the Ego [1937], II (D)) | |
| A reaction: This is the culmination of Sartre's attack (in 1937) on the Ego, paving the way for the freedom of existentialism. Personally I don't accept this picture of the Ego as a second-order fiction. My Ego is part of my relationship with the World. |
| 18283 | Language pictures the essence of the world [Wittgenstein] |
| Full Idea: The essence of language is a picture of the essence of the world. | |
| From: Ludwig Wittgenstein (Philosophical Remarks [1930], p.85), quoted by J. Alberto Coffa - The Semantic Tradition from Kant to Carnap 17 | |
| A reaction: Hence for a long time the study of language seemed to be the way to do metaphysics. Now they study mathematical logic, with the same hope. |
| 18282 | You can't believe it if you can't imagine a verification for it [Wittgenstein] |
| Full Idea: It isn't possible to believe something for which you cannot imagine some kind of verification. | |
| From: Ludwig Wittgenstein (Philosophical Remarks [1930], p.200), quoted by J. Alberto Coffa - The Semantic Tradition from Kant to Carnap 13 'Constr' | |
| A reaction: In 1930 LW was calling this his 'old principle'. As it stands here it is too vague to assert very much. |
