4 ideas
| 19396 | Wisdom is knowing all of the sciences, and their application [Leibniz] |
| Full Idea: Wisdom is a perfect knowledge of the principles of all the sciences and of the art of applying them. | |
| From: Gottfried Leibniz (On Wisdom [1693], 0) | |
| A reaction: 'Sciences' should be understood fairly broadly here (e.g. of architecture, agriculture, grammar). This is a scholar's vision of wisdom, very different from the notion of the wisest person in a village full of illiterate people. |
| 8920 | Equivalence relations are reflexive, symmetric and transitive, and classify similar objects [Lipschutz] |
| Full Idea: A relation R on a non-empty set S is an equivalence relation if it is reflexive (for each member a, aRa), symmetric (if aRb, then bRa), and transitive (aRb and bRc, so aRc). It tries to classify objects that are in some way 'alike'. | |
| From: Seymour Lipschutz (Set Theory and related topics (2nd ed) [1998], 3.9) | |
| A reaction: So this is an attempt to formalise the common sense notion of seeing that two things have something in common. Presumably a 'way' of being alike is going to be a property or a part |
| 19397 | Perfect knowledge implies complete explanations and perfect prediction [Leibniz] |
| Full Idea: The mark of perfect knowledge is that nothing appears in the thing under consideration which cannot be accounted for, and that nothing is encountered whose occurrence cannot be predicted in advance. | |
| From: Gottfried Leibniz (On Wisdom [1693], 1) | |
| A reaction: I would track both of these back to the concept of perfect understanding, which is admittedly a bit vague. Does a finite mind need to predict every speck of dust to have perfect knowledge? Do we have perfect knowledge of triangles? |
| 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. |
