| 16954 | Generalised talk of 'natural kinds' is unfortunate, as they vary too much [Dummett] |
| Full Idea: In my view, Kripke's promotion of 'natural kinds', coverning chemical substances and animal and plant species, is unfortunate, since these are rather different types of things, and words used for them behave differently. | |
| From: Michael Dummett (Could There Be Unicorns? [1983], 2) | |
| A reaction: My view is that the only significant difference among natural kinds is their degree of stability in character. Presumably particles, elements and particular molecules are fairly invariant, but living things evolve. |
| 24140 | Cause and effect is a hypothesis, based on our supposed willing of actions [Nietzsche] |
| Full Idea: Cause and effect is not a truth but rather a hypothesis - and indeed the one which we use to anthropomorphise the world for ourselves, bringing it in closer proximity to our feelings ('willing' is projected into it). | |
| From: Friedrich Nietzsche (Unpublished Notebooks 1884-85 [1884], 25[371]) | |
| A reaction: That is (I think), we read the gap between thought and action onto natural external events, dividing them up. We treat the flow of events as if they were agent causation. Modern theories seem close to Nietzsche's unified view. |
