7 ideas
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. |
23888 | Knowledge is beyond question, as an unavoidable component of thinking [Weil] |
Full Idea: The speaker refuses to pose the question of knowledge, since knowledge is a given that is mixed with thought, and that no thinking being can get away from. | |
From: Simone Weil (Philosophy [1941], p.42) | |
A reaction: On the whole I favour belief-first, but I take the primary purpose of minds to be navigation, and that needs facts, not hopeful beliefs. Weil's thought pushes me a bit towards the knowledge first view. |
7413 | Without confidence in our beliefs, how should we actually live? [Tuck] |
Full Idea: The central question for sceptics is if we lose confidence in the truth of most existing beliefs, then how do we actually live? | |
From: Richard Tuck (Hobbes [1989], Ch.4) | |
A reaction: Scepticism is not, of course, all or nothing. You can lead a 'normal' life in a virtual reality machine. I find it much more of a struggle to live if I lose faith in values, than if I lose faith in tables. |
23887 | Art (like philosophy) establishes a relation between world and self, and between oneself and others [Weil] |
Full Idea: Isn't true art a method for establishing a certain relation between the world and the self, and between oneself and others, and isn't that the equivalent of philosophy? | |
From: Simone Weil (Philosophy [1941], p.38) | |
A reaction: I hope the definition of 'true' art doesn't have to conform to achieving this relation. I suppose each good work of art shows you a distinctive way of relating to the world. An interesting thought (as so often with this thinker). |
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'? |
