16980 | We need a logical use of 'object' as predicate-worthy, and an 'ontological' use [Strawson,P] |
Full Idea: There is a good case for a conservative reform of the word 'object'. Objects in the 'logical' sense would be all predicate-worthy identifiabilia whatever. Objects in the 'ontological' sense would form one ontological category among many others. | |
From: Peter F. Strawson (Entity and Identity [1978], I n4) | |
A reaction: This ambiguity has caused me no end of confusion (and irritation!). I wish philosophers wouldn't hijack perfectly good English words and give them weird meanings. Nice to have a distinguished fellow like Strawson make this suggestion. |
16979 | It makes no sense to ask of some individual thing what it is that makes it that individual [Strawson,P] |
Full Idea: For no object is there a unique character or relation by which it must be identified if it is to be identified at all. This is why it makes no sense to ask, impersonally and in general, of some individual object what makes it the individual object it is. | |
From: Peter F. Strawson (Entity and Identity [1978], I) | |
A reaction: He links this remark with the claim that there is no individual essence, but he seems to view an individual essence as indispensable to recognition or individuation of the object, which I don't see. Recognise it first, work out its essence later. |
15645 | Nominal essence are the observable properties of things [Eagle] |
Full Idea: It is clear the nominal essences really are the properties of the things which have them: they are (a subset of) the observable properties of the things. | |
From: Antony Eagle (Locke on Essences and Kinds [2005], IV) | |
A reaction: I think this is wrong. The surface characteristics are all that is available to us, so our classifications must be based on those, but it is on the ideas of them, not their intrinsic natures. That is empiricsm! What makes the properties 'essential'? |
15642 | If kinds depend only on what can be observed, many underlying essences might produce the same kind [Eagle] |
Full Idea: If the kinds there are depend not on the essences of the objects but on their observed distinguishing particulars, ...then for any kind that we think there is, it is possible that there are many underlying essences which are observably indistinguishable. | |
From: Antony Eagle (Locke on Essences and Kinds [2005], IV) | |
A reaction: Eagle is commenting on Locke's reliance on nominal essences. This seems to be the genuine problem with jadeite and nephrite (both taken to be 'jade'), or with 'fool's gold'. This isn't an objection to Locke; it just explains the role of science. |
15643 | Nominal essence mistakenly gives equal weight to all underlying properties that produce appearances [Eagle] |
Full Idea: Nominal essence does not allow for gradations in significance for the underlying properties. Those are all essential for the object behaving as it observably does, and they must all be given equal weight when deciding what the object does. | |
From: Antony Eagle (Locke on Essences and Kinds [2005], IV) | |
A reaction: This is where 'scientific' essentialism comes in. If we take one object, or one kind of object, in isolation, Eagle is right. When we start to compare, and to set up controlled conditions tests, we can dig into the 'gradations' he cares about. |
15308 | Science is the reduction of diverse forces and powers to a smaller number that explain them [Kant] |
Full Idea: All natural philosophy consists in the reduction of given forces apparently diverse to a smaller number of forces and powers sufficient for the explication of the actions of the former. | |
From: Immanuel Kant (Metaphysical Foundations of Natural Science [1786], 534) | |
A reaction: I'm beginning to think science is just tracking of complex forces and powers back to fundamental forces and powers. In which case, that is the analysis Kant is talking of. The standard model of physics would thrill him to bits. |
15641 | Kinds are fixed by the essential properties of things - the properties that make it that kind of thing [Eagle] |
Full Idea: The natural thought is to think that real kinds are given only by classification on the basis of essential properties: properties that make an object the kind of thing that it is. | |
From: Antony Eagle (Locke on Essences and Kinds [2005], II) | |
A reaction: Circularity alert! Circularity alert! Essence gives a thing its kind - and hence we can see what the kind is? Test for a trivial property! Eagle is not unaware of these issues. Does he mean 'necessary' rather than 'essential'? |
