| 16608 | Ockham was an anti-realist about the categories [William of Ockham, by Pasnau] |
| Full Idea: Ockham is the scholastic paradigm of anti-realism with respect to the categories. | |
| From: report of William of Ockham (Summula philosophiae naturalis [1320]) by Robert Pasnau - Metaphysical Themes 1274-1671 05.3 | |
| A reaction: These are the ten categories mentioned in Aristotle's book 'Categories'. |
| 16599 | Ockham says matter must be extended, so we don't need Quantity [William of Ockham, by Pasnau] |
| Full Idea: Ockham regards Quantity as an entirely superfluous ontological category, …because matter is intrinsically extended. | |
| From: report of William of Ockham (Summula philosophiae naturalis [1320]) by Robert Pasnau - Metaphysical Themes 1274-1671 04.4 |
| 16681 | Matter gets its quantity from condensation and rarefaction, which is just local motion [William of Ockham] |
| Full Idea: Matter is made to have a greater or lesser quantity not through its receiving any absolute accident, but through condensation and rarefaction alone. Parts come more or less close together, which can happen with local motion. | |
| From: William of Ockham (Summula philosophiae naturalis [1320], I.13), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 15.1 | |
| A reaction: This is Ockham at his most modern, rejecting the odd idea of Quantity in favour of a modern corpuscular view of the mere motions of matter. |
| 12608 | Concepts are distinguished by roles in judgement, and are thus tied to rationality [Peacocke] |
| Full Idea: 'Concept' is a notion tied, in the classical Fregean manner, to cognitive significance. Concepts are distinct if we can judge rationally of one, without the other. Concepts are constitutively and definitionally tied to rationality in this way. | |
| From: Christopher Peacocke (Truly Understood [2008], 2.2) | |
| A reaction: It seems to a bit optimistic to say, more or less, that thinking is impossible if it isn't rational. Rational beings have been selected for. As Quine nicely observed, duffers at induction have all been weeded out - but they may have existed, briefly. |
| 12605 | A sense is individuated by the conditions for reference [Peacocke] |
| Full Idea: My basic Fregean idea is that a sense is individuated by the fundamental condition for something to be its reference. | |
| From: Christopher Peacocke (Truly Understood [2008], Intro) | |
| A reaction: For something to actually be its reference (as opposed to imagined reference), truth must be involved. This needs the post-1891 Frege view of such things, and not just the view of concepts as functions which he started with. |
| 12607 | Fregean concepts have their essence fixed by reference-conditions [Peacocke] |
| Full Idea: The Fregean view is that the essence of a concept is given by the fundamental condition for something to be its reference. | |
| From: Christopher Peacocke (Truly Understood [2008], 2.1) | |
| A reaction: Peacocke is a supporter of the Fregean view. How does this work for concepts of odd creatures in a fantasy novel? Or for mistaken or confused concepts? For Burge's 'arthritis in my thigh'? I don't reject the Fregean view. |
| 12609 | Concepts have distinctive reasons and norms [Peacocke] |
| Full Idea: For each concept, there will be some reasons or norms distinctive of that concept. | |
| From: Christopher Peacocke (Truly Understood [2008], 2.3) | |
| A reaction: This is Peacocke's bold Fregean thesis (and it sounds rather Kantian to me). I dislike the word 'norms' (long story), but reasons are interesting. The trouble is the distinction between being a reason for something (its cause) and being a reason for me. |
| 12604 | Any explanation of a concept must involve reference and truth [Peacocke] |
| Full Idea: For some particular concept, we can argue that some of its distinctive features are adequately explained only by a possession-condition that involves reference and truth essentially. | |
| From: Christopher Peacocke (Truly Understood [2008], Intro) | |
| A reaction: He reached this view via the earlier assertion that it is the role in judgement which key to understanding concepts. I like any view of such things which says that truth plays a role. |
| 12610 | Encountering novel sentences shows conclusively that meaning must be compositional [Peacocke] |
| Full Idea: The phenomenon of understanding sentences one has never encountered before is decisive against theories of meaning which do not proceed compositionally. | |
| From: Christopher Peacocke (Truly Understood [2008], 4.3) | |
| A reaction: I agree entirely. It seems obvious, as soon as you begin to slowly construct a long and unusual sentence, and follow the mental processes of the listener. |
| 23857 | People in power always try to increase their power [Weil] |
| Full Idea: Every human group that exercises power does so …in such a way as to increase that power. | |
| From: Simone Weil (Prospects: Proletarian Revolution? [1933], p.15) | |
| A reaction: Not so true in smaller institutions, but at the centre of power you can control how power is distributed, so the temptation is too much. |
| 23856 | Spontaneous movements are powerless against organised repression [Weil] |
| Full Idea: A spontaneous movement is fundamentally impotent when it comes to fighting against organised forces of repression. | |
| From: Simone Weil (Prospects: Proletarian Revolution? [1933], p.2) | |
| A reaction: Her example is the Paris Commune of 1870. Hence revolution requires prior penetration of the corridors of power. Hence the phenomenon of 'entryism' of more radical people into reformist parties. |
| 23859 | True democracy is the subordination of society to the individual [Weil] |
| Full Idea: In the subordination of society to the individual lies the definition of true democracy, and that of socialism as well. | |
| From: Simone Weil (Prospects: Proletarian Revolution? [1933], p.19) | |
| A reaction: This is the simplest definition of the liberal view. The big difference is whether this subordination is the starting point of political thinking, or the end result at which it aims. |
| 23858 | War is perpetuated by its continual preparations [Weil] |
| Full Idea: War perpetuates itself under the form of preparation for war. | |
| From: Simone Weil (Prospects: Proletarian Revolution? [1933], p.16) | |
| A reaction: There are periods when military preparations are scaled down, but a reason is always found to scale them back up again. |
| 23860 | Even if a drowning man is doomed, he should keep swimming to the last [Weil] |
| Full Idea: A man who is thrown overboard in the middle of the ocean ought not to let himself drown, even though there is very litte chance of his reaching safety, but to go on swimming till exhausted. | |
| From: Simone Weil (Prospects: Proletarian Revolution? [1933], p.21) | |
| A reaction: You might survive a little longer if you don't exhaust yourself! Not clear where her authority for 'ought' comes from, but it expresses an interesting attitude. |
