9327 | Organisms understand their worlds better if they understand themselves [Gulick] |
Full Idea: Organisms come to better understand their worlds by coming to better understand themselves and the ways in which their own structures engage their worlds. | |
From: Robert van Gulick (Mirror Mirror - Is That All? [2006], §III) | |
A reaction: Van Gulick is defending a higher-order theory of consciousness, but this strikes me as a good rationale for the target of philosophy, which has increasingly (since Descartes) focused on understanding our own minds. |
14064 | If a statue is identical with the clay of which it is made, that identity is contingent [Gibbard] |
Full Idea: Under certain conditions a clay statue is identical with the piece of clay of which it is made, and if this is so then the identity is contingent. | |
From: Allan Gibbard (Contingent Identity [1975], Intro) | |
A reaction: This initiated the modern debate about statues, and it is an attack on Kripke's claim that if two things are identical, then they are necessarily identical. Kripke seems right about Hesperus and Phosphorus, but not about the statue. |
14066 | A 'piece' of clay begins when its parts stick together, separately from other clay [Gibbard] |
Full Idea: A 'piece' of clay is a portion of clay which comes into existence when all of its parts come to be stuck to each other, and cease to be stuck to any clay which is not a part of the portion. | |
From: Allan Gibbard (Contingent Identity [1975], I) | |
A reaction: The sort of gormlessly elementary things that philosophers find themselves having to say, but this is a good basic assertion for a discussion of statue and clay, and I can't think of an objection to it. |
14067 | Clay and statue are two objects, which can be named and reasoned about [Gibbard] |
Full Idea: The piece of clay and the statue are 'objects' - that is to say, they can be designated with proper names, and the logic we ordinarily use will still apply. | |
From: Allan Gibbard (Contingent Identity [1975], I) | |
A reaction: An interesting indication of the way that 'object' is used in modern analytic philosophy, which may not be the way that it is used in ordinary English. The number 'seven', for example, seems to be an object by this criterion. |
14069 | We can only investigate the identity once we have designated it as 'statue' or as 'clay' [Gibbard] |
Full Idea: To ask meaningfully what that thing would be, we must designate it either as a statue or as a piece of clay. What that thing would be, apart from the way it is designated, is a question without meaning. | |
From: Allan Gibbard (Contingent Identity [1975], III) | |
A reaction: He obviously has a powerful point, but to suggest that we can only investigate a mysterious object once we have designated it as something sounds daft. It would ruin the fun of archaeology. |
14076 | Essentialism is the existence of a definite answer as to whether an entity fulfils a condition [Gibbard] |
Full Idea: Essentialism for a class of entities is that for one entity and a condition which it fulfills, the question of whether it necessarily fulfills the condition has a definite answer apart from the way the entity is specified. | |
From: Allan Gibbard (Contingent Identity [1975], VII) | |
A reaction: Yet another definition of essentialism, but resting, as usual in modern discussions, entirely on the notion of necessity. Kit Fine's challenge is that if you investigate the source of the necessity, it turns out to be an essence. |
14077 | Essentialism for concreta is false, since they can come apart under two concepts [Gibbard] |
Full Idea: Essentialism for the class of concrete things is false, since a statue necessarily fulfils a condition as 'Goliath', but only contingently fulfils it as 'lumpl'. On the other hand, essentialism for the class of individual concepts can be true. | |
From: Allan Gibbard (Contingent Identity [1975], VII) | |
A reaction: This rests on his definition of essentialism in Idea 14076. He rests his essentialism about concepts on an account given by Carnap ('Meaning and Necessity' §41). The essence of a statue and the essence of a lump of clay do seem distinct. |
14070 | A particular statue has sortal persistence conditions, so its origin defines it [Gibbard] |
Full Idea: A proper name like 'Goliath' denotes a thing in the actual world, and invokes a sortal with certain persistence criteria. Hence its origin makes a statue the statue that it is, and if statues in different worlds have the same beginning, they are the same. | |
From: Allan Gibbard (Contingent Identity [1975], III) | |
A reaction: Too neat. There are vague, ambiguous and duplicated origins. Persistence criteria can shift during the existence of a thing (like a club which changes its own constitution). In replicated statues, what is the status of the mould? |
14073 | Claims on contingent identity seem to violate Leibniz's Law [Gibbard] |
Full Idea: The most prominent objection to contingent identity (as in the case of the statue and its clay) is that it violates Leibniz's Law. | |
From: Allan Gibbard (Contingent Identity [1975], V) | |
A reaction: Depends what you mean by a property. The trickiest one would be that the statue has (right now) a disposition to be worth a lot, but the clay doesn't. But I don't think that is really a property of the statue. Properties are a muddle. |
14065 | Two identical things must share properties - including creation and destruction times [Gibbard] |
Full Idea: For two things to be strictly identical, they must have all properties in common. That means, among other things, that they must start to exist at the same time and cease to exist at the same time. | |
From: Allan Gibbard (Contingent Identity [1975], I) | |
A reaction: I don't accept that coming into existence at time t is a 'property' of a thing. Coincident objects give you the notion of 'existing as' something, which complicates the whole story. |
14074 | Leibniz's Law isn't just about substitutivity, because it must involve properties and relations [Gibbard] |
Full Idea: As a general law of substitutivity of identicals, Leibniz's Law is false. It is a law about properties and relations, that if two things are identical, they have the same properties and relations. It only works in contexts which attribute those. | |
From: Allan Gibbard (Contingent Identity [1975], V) | |
A reaction: I'm not convinced about relations, which are not intrinsic properties. Under different descriptions, the relations to human minds might differ. |
14072 | Possible worlds identity needs a sortal [Gibbard] |
Full Idea: Identity across possible worlds makes sense only with respect to a sortal | |
From: Allan Gibbard (Contingent Identity [1975], IV) | |
A reaction: See Gibbard's other ideas from this paper. I fear that the sortal invoked is too uncertain and slippery to do any useful job, and I can't see any principled difficulty with naming something before you can think of a sortal for it. |
14078 | Only concepts, not individuals, can be the same across possible worlds [Gibbard] |
Full Idea: It is meaningless to talk of the same concrete thing in different possible worlds, ...but it makes sense to speak of the same individual concept, which is just a function which assigns to each possible world in a set an individual in that world. | |
From: Allan Gibbard (Contingent Identity [1975], VII) | |
A reaction: A lovely bold response to the problem of transworld identity, but one which needs investigation. It sounds very promising to me. 'Aristotle' is a cocept, not a name. There is no separate category of 'names'. Wow. (Attach dispositions to concepts?). |
14079 | Kripke's semantics needs lots of intuitions about which properties are essential [Gibbard] |
Full Idea: To use Kripke's semantics, one needs extensive intuitions that certain properties are essential and others accidental. | |
From: Allan Gibbard (Contingent Identity [1975], X) | |
A reaction: As usual, we could substitute the word 'necessary' for 'essential' without changing his meaning. If we are always referring to 'our' Hubert Humphrey is speculations about him, then nearly all of his properties will be necessary ones. |
9325 | In contrast with knowledge, the notion of understanding emphasizes practical engagement [Gulick] |
Full Idea: In contrast with standard notions of knowledge, the concept of understanding emphasizes the element of practical engagement from the outset. | |
From: Robert van Gulick (Mirror Mirror - Is That All? [2006], §II) | |
A reaction: This could be the very interesting germ of a huge revolution in our approach to epistemology, which I find rather appealing. Plato's desire that knowledge should have 'logos' seems to me in the same area. It sounds rather internalist, which is good. |
9326 | Knowing-that is a much richer kind of knowing-how [Gulick] |
Full Idea: Knowing-that is a much richer kind of knowing-how. | |
From: Robert van Gulick (Mirror Mirror - Is That All? [2006], §II) | |
A reaction: This thought could rather rapidly revive the discredited notion of knowing-how. I think it might slot into an account of the mind in terms of levels, so that my internalist view of knowledge emerges at higher levels, built on more basic responses. |
9319 | Is consciousness a type of self-awareness, or is being self-aware a way of being conscious? [Gulick] |
Full Idea: Is consciousness just a special type of self-awareness, or is being self-aware a special way of being conscious? | |
From: Robert van Gulick (Mirror Mirror - Is That All? [2006], Intro) | |
A reaction: This is a really good key question, which has hovered over the debate since Locke's definition of a person (as 'self-aware'). I take the self to be a mechanism of most brains, which is prior to consciousness. Maybe the two are inseparable. |
9320 | Higher-order theories divide over whether the higher level involves thought or perception [Gulick] |
Full Idea: Higher-order thought (HOT) models treat metastates as thought-like, and higher-order perception (HOP) models regard them as at least quasi-perceptual and resulting from some form of inner monitoring or inner sense. | |
From: Robert van Gulick (Mirror Mirror - Is That All? [2006], §I) | |
A reaction: I would understand 'thought' to at least partially involve judgements. The HOT theory (Carruthers) seems to suit epistemological foundationalists, who want truth to enter on the ground floor. This pushes me towards the HOP model (Lycan) as more plausible. |
9321 | Higher-order models reduce the problem of consciousness to intentionality [Gulick] |
Full Idea: Higher-order models would effectively reduce the problem of consciousness to that of intentionality. | |
From: Robert van Gulick (Mirror Mirror - Is That All? [2006], §I) | |
A reaction: This gives the bigger picture - that higher-order theories are the cutting edge of attempts to give a naturalistic, reductivist account of consciousness. That seems to be the only way to go, so we should encourage them in the enterprise. |
9322 | Maybe qualia only exist at the lower level, and a higher-level is needed for what-it-is-like [Gulick] |
Full Idea: Some higher-order theorists say we have qualitative but unconscious mental states of color or pain (qualia), but there is nothing it is like to be in such a state, which needs higher-order awareness. The meta-states are devoid of qualia. | |
From: Robert van Gulick (Mirror Mirror - Is That All? [2006], §I.5) | |
A reaction: He calls this the 'stranded qualia' problem. Clearly one begins to sharpen Ockham's Razor at this point, if the higher-level state isn't contributing something. I don't rule out unconscious qualia. The strength of a real pain is distorted in a dream. |
14071 | Naming a thing in the actual world also invokes some persistence criteria [Gibbard] |
Full Idea: The reference of a name in the actual world is fixed partly by invoking a set of persistence criteria which determine what thing it names. | |
From: Allan Gibbard (Contingent Identity [1975], III) | |
A reaction: This is offered as a modification to Kripke, to deal with the statue and clay. I fear that the 'persistence criteria' may be too vague, and too subject to possible change after the origin, to do the job required. |
6005 | Animals are dangerous and nourishing, and can't form contracts of justice [Hermarchus, by Sedley] |
Full Idea: Hermarchus said that animal killing is justified by considerations of human safety and nourishment and by animals' inability to form contractual relations of justice with us. | |
From: report of Hermarchus (fragments/reports [c.270 BCE]) by David A. Sedley - Hermarchus | |
A reaction: Could the last argument be used to justify torturing animals? Or could we eat a human who was too brain-damaged to form contracts? |
9324 | From the teleopragmatic perspective, life is largely an informational process [Gulick] |
Full Idea: From the teleopragmatic perspective, life itself is largely an informational process. | |
From: Robert van Gulick (Mirror Mirror - Is That All? [2006]) | |
A reaction: From the cynical perspective a human is just 'blood and foul smell in a bag', but that may not give you whole story. The point here is that the informational view will cover both the genetic and the mental levels of human life. True but unilluminating? |
