| 12549 | Nothing is so beautiful to the eye as truth is to the mind [Locke] |
| Full Idea: Nothing is so beautiful to the eye as truth is to the mind. | |
| From: John Locke (Essay Conc Human Understanding (2nd Ed) [1694], 4.03.20) | |
| A reaction: This is historically interesting, if we ask whether anyone in the centuries preceding Locke would ever have written such a remark. A deep historical question is why the value of pure truth went up so sharply in the early Enlightenment. |
| 23520 | Truth has had to be fought for, and normal life must be sacrificed to achieve it [Nietzsche] |
| Full Idea: Truth has had to be fought for every step of the way, almost everything else dear to our hearts, on which our love and our trust in life depend, has had to be sacrificed to it. | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], 50) | |
| A reaction: This, in one of his final works, seems to contradict every idea that Nietzsche is the high priest of relativism about truth. He (and Foucault) and interested in the social role of truth, but are not so daft as to reject its possibility. |
| 2914 | One must never ask whether truth is useful [Nietzsche] |
| Full Idea: One must never ask whether truth is useful. | |
| From: Friedrich Nietzsche (The Anti-Christ [1889], Fore) |
| 12558 | Truth only belongs to mental or verbal propositions [Locke] |
| Full Idea: Truth only belongs to propositions: whereof there are two sorts, viz. mental and verbal | |
| From: John Locke (Essay Conc Human Understanding (2nd Ed) [1694], 4.05.02) | |
| A reaction: I think it is important to retain 'mental' propositions, so that animals are allowed to think correctly or wrongly about things. I don't think Locke gives much thought to the ontological status of propositions. |
| 12522 | It is propositions which are true or false, though it is sometimes said of ideas [Locke] |
| Full Idea: Truth and falsehood belong, in propriety of speech, only to propositions; yet ideas are oftentimes termed 'true' or 'false ...though I think there is still some secret or tacit proposition. | |
| From: John Locke (Essay Conc Human Understanding (2nd Ed) [1694], 2.32.01) | |
| A reaction: It is not quite clear, I think, what Locke means by 'proposition'. If it means sentences, then there are lots of problem cases like 'I am ill' (who is speaking?). I demand a theory of truth that allows animals to think truths. See Idea 12523. |
| 12523 | If they refer to real substances, 'man' is a true idea and 'centaur' a false one [Locke] |
| Full Idea: The two ideas, of a man and a centaur, supposed to be the ideas of real substances, are the one true and the other false. | |
| From: John Locke (Essay Conc Human Understanding (2nd Ed) [1694], 2.32.05) | |
| A reaction: Locke says (Idea 12522) that there is probably a proposition hidden behind this. We might say that 'man' has a reference and 'centaur' does not (strictly). Is successful reference a species of truth? 'Pick out the llama' - child points - 'that's right!' |
