8 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. |
| 17945 | Forms are not a theory of universals, but an attempt to explain how predication is possible [Nehamas] |
| Full Idea: The theory of Forms is not a theory of universals but a first attempt to explain how predication, the application of a single term to many objects - now considered one of the most elementary operations of language - is possible. | |
| From: Alexander Nehamas (Introduction to 'Virtues of Authenticity' [1999], p.xxvii) |
| 17946 | Only Tallness really is tall, and other inferior tall things merely participate in the tallness [Nehamas] |
| Full Idea: Only Tallness and nothing else really is tall; everything else merely participates in the Forms and, being excluded from the realm of Being, belongs to the inferior world of Becoming. | |
| From: Alexander Nehamas (Introduction to 'Virtues of Authenticity' [1999], p.xxviii) | |
| A reaction: This is just as weird as the normal view (and puzzle of participation), but at least it makes more sense of 'metachein' (partaking). |
| 17944 | 'Episteme' is better translated as 'understanding' than as 'knowledge' [Nehamas] |
| Full Idea: The Greek 'episteme' is usually translated as 'knowledge' but, I argue, closer to our notion of understanding. | |
| From: Alexander Nehamas (Introduction to 'Virtues of Authenticity' [1999], p.xvi) | |
| A reaction: He agrees with Julia Annas on this. I take it to be crucial. See the first sentence of Aristotle's 'Metaphysics'. It is explanation which leads to understanding. |
| 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. |
| 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. |
| 19414 | Men are related to animals, which are related to plants, then to fossils, and then to the apparently inert [Leibniz] |
| Full Idea: Men are related to animals, these to plants, and the latter directly to fossils which will be linked in their turn to bodies which the senses and the imagination represent to us as perfectly dead and formless. | |
| From: Gottfried Leibniz (Letters to Varignon [1702], 1702) | |
| A reaction: Leibniz would be a bit surprised to find the way in which this has turned out to be largely true, since he is basing it on his picture of a hierarchy of monads. Nevertheless, the idea that we are all related wasn't invented in 1859. |
