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. |
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? |
15282 | Facts should be deducible from the theory and initial conditions, and prefer the simpler theory [Osiander, by Harré/Madden] |
Full Idea: The two positivist criteria for a scientific theory are that the facts must be deducible from the theory together with initial conditions, and if there is more than one theory the simplest must be chosen. | |
From: report of Andreas Osiander (Preface to 'De Revolutionibus' [1543]) by Harré,R./Madden,E.H. - Causal Powers 7.I | |
A reaction: Harré and Madden cite this as a famous early statement of positivism. It seems to combine Hempel and Lewis very concisely. Wrong, of course. It does not, though, appear to mention 'laws'. |
468 | Musical performance can reveal a range of virtues [Damon of Ath.] |
Full Idea: In singing and playing the lyre, a boy will be likely to reveal not only courage and moderation, but also justice. | |
From: Damon (fragments/reports [c.460 BCE], B4), quoted by (who?) - where? |
