3 ideas
16635 | Incorporeal substances are powers or forces [Descartes, by Pasnau] |
Full Idea: In one of his last letters Descartes describes incorporeal substances as 'powers or forces'. | |
From: report of René Descartes (Two letters on mind [1649], Feb 1649) by Robert Pasnau - Metaphysical Themes 1274-1671 08.4 | |
A reaction: Only a glimmer, but I really like this idea. (Ellis flirts with it somewhere). Minds are deeply and intrinsically active things. Try ceasing to think for five minutes. Apparently 12th century Cistercian authors were keen on the idea. |
9471 | Intensions are creatures of darkness which should be exorcised [Quine] |
Full Idea: Intensions are creatures of darkness and I shall rejoice with the reader when they are exorcised. | |
From: Willard Quine (Quantifiers and Propositional Attitudes [1955], §II) | |
A reaction: Quine seems to be in a diminshing minority with this view. For 'intensions' read 'meanings', presumably. |
16684 | Impenetrability only belongs to the essence of extension [Descartes] |
Full Idea: It is demonstrated that impenetrability belongs to the essence of extension and not to the essence of any other thing. | |
From: René Descartes (Two letters on mind [1649], More, Apr 1649), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 15.5 | |
A reaction: I'm not sure that I understand how pure extension can be impenetrable. |
