6 ideas
| 5637 | Nowadays logic is seen as the science of extensions, not intensions [Scruton] |
| Full Idea: Logicians have come increasingly to realise that logic is the science not of the intension, but of the extension of terms. | |
| From: Roger Scruton (Short History of Modern Philosophy [1981], Ch.4) | |
| A reaction: I take this to be because the notion of a 'set' is basic, which is defined strictly in terms of its members. This move is probably because we can be clear about extensions, but not intensions. Tidiness is no substitute for complex truth. |
| 3448 | Do new ideas increase the weight of the brain? [Dance] |
| Full Idea: If someone gives you a piece of information, does your brain suddenly become heavier? | |
| From: Adam Dance (works [2001]), quoted by PG - Db (ideas) | |
| A reaction: A beautifully simple question, which is a reductio of the idea that information is simply a physical object. The question points to a functionalist account of brain activity. |
| 5636 | Cartesian 'ideas' confuse concepts and propositions [Scruton] |
| Full Idea: Cartesian 'ideas' seem to be both concepts and propositions at once. | |
| From: Roger Scruton (Short History of Modern Philosophy [1981], Ch.4) | |
| A reaction: This seems to be the simple reason why modern philosophers don't like this seventeenth century notion. There is something slightly too tidy about the modern notion of propositions built out of concepts. Animals see propositions in a flash. |
| 20581 | If men are born free, are women born slaves? [Astell] |
| Full Idea: If all men are born free, how is it that all women are born slaves? | |
| From: Mary Astell (A Serious Proposal to the Ladies I [1694]), quoted by Johanna Oksala - Political Philosophy: all that matters Ch.9 | |
| A reaction: What a magnificent question for such an early date. She is said to have been the 'first British feminist'. It is not just a feminist point, but a strong objection to the idea that anyone is 'born free'. Because there is no way to tell if it is true. |
| 5660 | Allegiance is prior to the recognition of individual rights [Scruton] |
| Full Idea: Personally I regard allegiance, in the manner of Hegel, as prior to the recognition of individual rights. | |
| From: Roger Scruton (Short History of Modern Philosophy [1981], Bibliog) | |
| A reaction: Scruton notoriously generates rather right-wing views from this basis, but it is also the basis of communitarianism, which can take a softer form. It seems to me self-evident that rights cannot be the prime concept in a society. What society? |
| 5653 | A right is a power which is enforced in the name of justice [Scruton] |
| Full Idea: Rights are enforced in the name of justice, whereas power is enforced come what may. | |
| From: Roger Scruton (Short History of Modern Philosophy [1981], Ch.14) | |
| A reaction: Presumably rights can be claimed as well as enforced, and the notion of a natural right is at least a discussable concept, as in the 'right' of self-defence. Scruton offers us a very right-wing definition of rights. |
