4298 | All items of possible human knowledge are interconnected, and can be reached by inference [Descartes] |
Full Idea: All the items of knowledge that lie within the reach of the human mind are linked together with a marvellous bond, and can be derived from each other by necessary inferences. | |
From: René Descartes (unfinished dialogue [1649]) | |
A reaction: It does seem that God ought to be able to infer all empirical facts from first principles. But how do you get started? |
9560 | S5 provides the correct logic for necessity in the broadly logical sense [Fine,K] |
Full Idea: S5 provides the correct logic for necessity in the broadly logical sense. | |
From: Kit Fine (Model Theory for Modal Logic I [1978], 151), quoted by Charles Chihara - A Structural Account of Mathematics | |
A reaction: I have no view on this, but I am prejudiced in favour of the idea that there is a correct logic for such things, whichever one it may be. Presumably the fact that S5 has no restrictions on accessibility makes it more comprehensive and 'metaphysical'. |
22086 | The most important aspect of a human being is not reason, but passion [Kierkegaard, by Carlisle] |
Full Idea: Kierkegaard insisted that the most important aspect of a human being is not reason, but passion. | |
From: report of Søren Kierkegaard (works [1845]) by Clare Carlisle - Kierkegaard: a guide for the perplexed Intro | |
A reaction: Hume comes to mind for a similar view, but in character Hume was far more rational than Kierkegaard. |
