| 12582 | The function of beliefs is to produce beliefs-that-p when p [Millikan] |
| Full Idea: Presumably it is a proper function of the belief-manufacturing mechanisms in John to produce beliefs-that-p only if and when p. | |
| From: Ruth Garrett Millikan (Thoughts without Laws [1986], p.69), quoted by Christopher Peacocke - A Study of Concepts 5.2 | |
| A reaction: This is the 'teleological' account of belief, which is trying to fit belief into an evolutionary view of humans. It is doubtful whether you can say mental states are just their 'proper' function, because then piano-playing becomes a puzzle. |
| 15160 | Davidson rejected ordinary meaning, and just used truth and reference instead [Davidson, by Soames] |
| Full Idea: Davidson held that knowledge of truth and reference could give us a notion of meaning. He embraced Quine's rejection of analyticity, synonymy and ordinary meaning, and substituted truth and reference, when there was something genuine to capture. | |
| From: report of Donald Davidson (Semantics for Natural Languages [1970]) by Scott Soames - Philosophy of Language 2.3 | |
| A reaction: I always get a warm glow when anyone suggests that the concept of meaning involves the concept of truth. I largely reject Quine. Davidson made a helpful suggestion! |
| 14612 | Davidson aimed to show that language is structured by first-order logic [Davidson, by Smart] |
| Full Idea: Davidson's program was to show the underlying structure of natural languages as that of first-order logic. | |
| From: report of Donald Davidson (Semantics for Natural Languages [1970], 2) by J.J.C. Smart - The Tenseless Theory of Time 2 | |
| A reaction: First order logic just reasons about a domain of objects with predicates attached to them. Language appears to refer to properties and relations as well as objects. |
| 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. |
