| 21552 | Common speech is vague; its vocabulary and syntax must be modified, for precision [Russell] |
| Full Idea: I am persuaded that common speech is full of vagueness and inaccuracy, and that any attempt to be precise and accurate requires modification of common speech both as regards vocabulary and as regards syntax. | |
| From: Bertrand Russell (Mr Strawson on Referring [1957], p.123) | |
| A reaction: It is interesting that he cites the syntax of ordinary language, as well as the vocabulary. The implication is that vagueness can also be a feature of syntax (and hence his pursuit of logical form), which is not normally mentioned |
| 21551 | Empirical words need ostensive definition, which makes them egocentric [Russell] |
| Full Idea: The meanings of all empirical words depend ultimately upon ostensive definitions, ostensive definitions depend upon experience, and that experience is egocentric. | |
| From: Bertrand Russell (Mr Strawson on Referring [1957], p.122) | |
| A reaction: He seems to imply that this makes them partly subjective, but I don't see why an objective consensus can't be reached when making an ostensive definition. We just need to clearly agree what 'that' refers to. |
| 3291 | Emergent properties appear at high levels of complexity, but aren't explainable by the lower levels [Nagel] |
| Full Idea: The supposition that a diamond or organism should truly have emergent properties is that they appear at certain complex levels of organisation, but are not explainable (even in principle) in terms of any more fundamental properties of the system. | |
| From: Thomas Nagel (Panpsychism [1979], p.186) |
| 1556 | By nature people are close to one another, but culture drives them apart [Hippias] |
| Full Idea: I regard you all as relatives - by nature, not by convention. By nature like is akin to like, but convention is a tyrant over humankind and often constrains people to act contrary to nature. | |
| From: Hippias (fragments/reports [c.430 BCE]), quoted by Plato - Protagoras 337c8 |
| 21550 | Science reduces indexicals to a minimum, but they can never be eliminated from empirical matters [Russell] |
| Full Idea: It is of the essence of a scientific account of the world to reduce to a minimum the egocentric element in assertion, but success in this attempt is a matter of degree, and is never complete where empirical matter is concerned. | |
| From: Bertrand Russell (Mr Strawson on Referring [1957], p.121) | |
| A reaction: He cites ostensive definitions. The key issue is whether they can be wholly eliminated when we try to be objective. Russell here endorses Perry's claim that they never go away. Personally I just think that (if so) we should try harder. |
| 3290 | Given the nature of heat and of water, it is literally impossible for water not to boil at the right heat [Nagel] |
| Full Idea: Given what heat is and what water is, it is literally impossible for water to be heated beyond a certain point at normal atmospheric pressure without boiling. | |
| From: Thomas Nagel (Panpsychism [1979], p.186) |
