16034 | Form is not a separate substance, but just the manner, modification or 'stamp' of matter [Boyle] |
Full Idea: I understand the word 'form' to mean, not a real substance distinct from matter, but only the matter itself of a natural body, with its peculiar manner of existence [corpuscular structure], which may be called its 'essential modification' or 'stamp'. | |
From: Robert Boyle (The Origin of Forms and Qualities [1666], p.324), quoted by Jan-Erik Jones - Real Essence §3 | |
A reaction: I don't think Aristotle ever thought that a form was separate from its matter, let alone qualifying as a substance. On the whole, Boyle attacks scholastic philosophy, rather than Aristotle. |
15953 | To cite a substantial form tells us what produced the effect, but not how it did it [Boyle] |
Full Idea: If it be demanded why rhubarb purges choler, snow dazzles the eyes rather than grass etc., that these effects are performed by substantial forms of the respective bodies is at best but to tell me what is the agent, not how the effect is wrought. | |
From: Robert Boyle (The Origin of Forms and Qualities [1666], p.47?), quoted by Peter Alexander - Ideas, Qualities and Corpuscles 01.2 | |
A reaction: This is the problem of the 'virtus dormitiva' of opium (which at least tells you it was the opium what done it). I take Aristotle to have aspired to a lot more than this. He wanted a full definition, which would contain lots of information about the form. |
6127 | 'Unrestricted composition' says any two things can make up a third thing [Merricks] |
Full Idea: If my dog and the top half of my tree compose an object, this is defended under the title of 'unrestricted (universal) composition', the thesis that any two things compose something. | |
From: Trenton Merricks (Objects and Persons [2003], §1.II) | |
A reaction: David Lewis is cited amongst those defending this thesis. My intuition is against this thesis, because I think identity is partly dictated by nature, and is not entirely conventional. You can force an identity, but you feel the 'restriction'. |
6131 | Composition as identity is false, as identity is never between a single thing and many things [Merricks] |
Full Idea: One of the most obvious facts about identity is that it holds one-one (John and Mr Smith) and perhaps many-many (John+Mary and Mr Smith+Miss Jones), but never one-many. It follows that composition as identity (things are their parts) is false. | |
From: Trenton Merricks (Objects and Persons [2003], §1.IV) | |
A reaction: This assumes that 'having identity' and 'being identical to' are the same concept. I agree with his conclusion, but am not convinced by the argument. I'm not even quite clear why John and May can't be identical to the Smiths. |
6132 | Composition as identity is false, as it implies that things never change their parts [Merricks] |
Full Idea: Composition as identity implies that no persisting object ever changes its parts, which is clearly false, so composition as identity is false. | |
From: Trenton Merricks (Objects and Persons [2003], §1.IV) | |
A reaction: Presumably Lewis can say that when a thing subtly changes its parts, it really does lose its strict identity, but becomes another 'time-slice' or close 'counterpart' of the original object. This is a coherent view, but I disagree. I'm a believer. |
6141 | There is no visible difference between statues, and atoms arranged statuewise [Merricks] |
Full Idea: If we imagine a world like ours except that, while there are atoms arranged statuewise in that world, there are no statues, ...no amount of looking around could distinguish that imagined world from ours. | |
From: Trenton Merricks (Objects and Persons [2003], §2.V) | |
A reaction: This is one of his arguments for ontological eliminativism about physical objects. If we accept the argument, it will wreak havoc with our entire ontology, and we will end up anti-realists. I say you have to see statues - you just can't miss them. |
6130 | 'Composition' says things are their parts; 'constitution' says a whole substance is an object [Merricks] |
Full Idea: Composition as identity claims that a single object is identical with the many parts it comprises; constitution as identity says that a single object (a statue) is identical with a single object (clay) that 'constitutes' it. | |
From: Trenton Merricks (Objects and Persons [2003], §1 n11) | |
A reaction: The constitution view has been utilised (by Lynn Rudder Baker) to give an account of personal identity as constituted by a human body. Neither sounds quite right to me; the former view misses something about reality; the latter doesn't explain much. |
6138 | It seems wrong that constitution entails that two objects are wholly co-located [Merricks] |
Full Idea: Many philosophers deny that two numerically distinct physical objects could be 'wholly co-located'. | |
From: Trenton Merricks (Objects and Persons [2003], §2.III) | |
A reaction: A fish can be located in a river; the Appenines can be located in Italy. If you accept the objection you will probably have to accept identity-as-composition, or object-eliminativism. One object can have two causal roles, supporting two identities. |
6128 | Objects decompose (it seems) into non-overlapping parts that fill its whole region [Merricks] |
Full Idea: Intuitively, an object's parts at one level of decomposition are parts of that object that do not overlap and that, collectively, fill the whole region the object fills. | |
From: Trenton Merricks (Objects and Persons [2003], §1.II) | |
A reaction: A nice case where 'intuition' must be cited as the basis for the claim, and yet it is hard to see how anyone could possibly disagree. Exhibit 73 in favour of rationalism. This ideas shows the structure of nature and the workings of our minds. |
