5 ideas
| 3534 | To be is to have causal powers [Alexander,S] |
| Full Idea: To be is to have causal powers. | |
| From: Samuel Alexander (works [1927], §4), quoted by Jaegwon Kim - Nonreductivist troubles with ment.causation | |
| A reaction: This is sometimes called Alexander's Principle. It is first found in Plato, and is popular with physicalists, but there are problem cases... A thing needs to exist in order to have causal powers. To exist is more than to be perceived. |
| 14380 | The distinction between necessary and essential properties can be ignored [Rocca] |
| Full Idea: Some philosophers distinguish between necessary properties and essential properties. This distinction is irrelevant to my purposes. Following Yablo, I shall ignore this distinction in what follows. | |
| From: Michael della Rocca (Essentialists and Essentialism [1996], I n1) | |
| A reaction: This is two years after Kit Fine's seminal paper suggesting the distinction is real. The first step towards a good metaphysics is to realise that Della Rocca and Yablo have made a horrible mistake. |
| 3398 | Epiphenomenalism makes the mind totally pointless [Alexander,S] |
| Full Idea: Epiphenomenalism supposes something to exist in nature which has nothing to do and no purpose to serve. | |
| From: Samuel Alexander (works [1927]), quoted by Jaegwon Kim - Philosophy of Mind p.129 | |
| A reaction: An objection, but not, I think, a strong one. The fact, for example, that sweat is shiny is the result of good evolutionary reasons, but I cannot think of any purpose which it serves. All events which are purposeful are likely to have side-effects. |
| 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. |
