| 9786 | Philosophers working like teams of scientists is absurd, yet isolation is hard [Cartwright,R] |
| Full Idea: The notion that philosophy can be done cooperatively, in the manner of scientists or engineers engaged in a research project, seems to me absurd. And yet few philosophers can survive in isolation. | |
| From: Richard Cartwright (Intro to 'Philosophical Essays' [1987], xxi) | |
| A reaction: This why Nietzsche said that philosophers were 'rare plants'. |
| 9784 | A false proposition isn't truer because it is part of a coherent system [Cartwright,R] |
| Full Idea: You do not improve the truth value of a false proposition by calling attention to a coherent system of propositions of which it is one. | |
| From: Richard Cartwright (Intro to 'Philosophical Essays' [1987], xi) | |
| A reaction: We need to disentangle the truth-value from the justification here. If it is false, then we can safely assume that is false, but we are struggling to decide whether it is false, and we want all the evidence we can get. Falsehood tends towards incoherence. |
| 13197 | The notion of substance is one of the keys to true philosophy [Leibniz] |
| Full Idea: I consider the notion of substance to be one of the keys to the true philosophy. ....I imagine that philosophers will one day know the notion of substance a bit better than they do now. | |
| From: Gottfried Leibniz (Letters to Thomas Burnett [1703], 1699.01.20/30) | |
| A reaction: This is a controversial remark at this historical moment, when the apparent Aristotelian commitment to substances was becoming discredited. Personally I would eliminate substance, but not just because physicists don't refer to it. |
| 5845 | Niceratus learnt the whole of Homer by heart, as a guide to goodness [Xenophon] |
| Full Idea: Niceratus said that his father, because he was concerned to make him a good man, made him learn the whole works of Homer, and he could still repeat by heart the entire 'Iliad' and 'Odyssey'. | |
| From: Xenophon (Symposium [c.391 BCE], 3.5) | |
| A reaction: This clearly shows the status which Homer had in the teaching of morality in the time of Socrates, and it is precisely this acceptance of authority which he was challenging, in his attempts to analyse the true basis of virtue |
| 13198 | Gravity is within matter because of its structure, and it can be explained. [Leibniz] |
| Full Idea: I believe that both gravity and elasticity are in matter only because of the structure of the system and can be explained mechanically or through impulsion. | |
| From: Gottfried Leibniz (Letters to Thomas Burnett [1703], 1699 draft) | |
| A reaction: The significance of this remark is that gravity is held (in full knowledge of Newton's work) to be within matter, and not imposed from the outside. I believe we now postulate a particle as part of the explanation. |
