| 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. |
| 19413 | If we know what is good or rational, our knowledge is extended, and our free will restricted [Leibniz] |
| Full Idea: The more perfect one is, the more one is determined to the good, and so is more free at the same time. ...Our power and knowledge are more extended, and our will much the more limited within the bounds of perfect reason. | |
| From: Gottfried Leibniz (Letters to Pierre Bayle [1702], 1702) | |
| A reaction: I like this idea, which seems to me to derive from Aquinas. When I choose to eat and drink each day, or agree that 7+5 is 12, I don't complain about my lack of freedom in the choices. Goodness and reason are constraints I welcome. |
| 13304 | Learned men gain more in one day than others do in a lifetime [Posidonius] |
| Full Idea: In a single day there lies open to men of learning more than there ever does to the unenlightened in the longest of lifetimes. | |
| From: Posidonius (fragments/reports [c.95 BCE]), quoted by Seneca the Younger - Letters from a Stoic 078 | |
| A reaction: These remarks endorsing the infinite superiority of the educated to the uneducated seem to have been popular in late antiquity. It tends to be the religions which discourage great learning, especially in their emphasis on a single book. |
| 20820 | Time is an interval of motion, or the measure of speed [Posidonius, by Stobaeus] |
| Full Idea: Posidonius defined time thus: it is an interval of motion, or the measure of speed and slowness. | |
| From: report of Posidonius (fragments/reports [c.95 BCE]) by John Stobaeus - Anthology 1.08.42 | |
| A reaction: Hm. Can we define motion or speed without alluding to time? Looks like we have to define them as a conjoined pair, which means we cannot fully understand either of them. |
