| 14044 | The perceived accidental properties of bodies cannot be conceived of as independent natures [Epicurus] |
| Full Idea: The shapes, colours, sizes and weights which are predicated of body as accidents, ...and are known by sense-perception, must not be thought of as independent natures (for that is inconceivable). | |
| From: Epicurus (Letter to Herodotus [c.293 BCE], 68) | |
| A reaction: I take this to be an anti-platonist remark, though he is not denying that the accidental properties may have some universal character. I'm struck by how close the basic metaphysics of Epicurus is to that of Aristotle. |
| 14045 | Accidental properties give a body its nature, but are not themselves bodies or parts of bodies [Epicurus] |
| Full Idea: Accidental qualities are not non-existent, nor are they distinct corporeal entities inhering in the body, nor parts of it. We should think that the whole body throughout derives its permanent nature from these properties, though not as a compound of them. | |
| From: Epicurus (Letter to Herodotus [c.293 BCE], 69) | |
| A reaction: 'Permanent' nature sounds more like essential than accidental properties. This is uncomfortably negative in its attempt to pin down what accidental properties are. The last bit seems to deny the bundle view of objects. Would he like tropes? |
| 15312 | We get the idea of power by abstracting from ropes, magnets and electric shocks [Priestley] |
| Full Idea: A rope sustains weight, a magnet attracts iron, a charged electrical jar gives a shock, and from these and other similar observations, we get the idea of power, universally and abstractly considered. | |
| From: Joseph Priestley (Theological and other works [1790], p.191), quoted by Harré,R./Madden,E.H. - Causal Powers 9.II.B | |
| A reaction: I agree with this, in that we appear to be observing powers directly, and are not observing something which can then be reduced to non-powers. Nature just can't be a set of inert structures, with forces 'imposed' on them. |
