| 7450 | In the medieval view, only deduction counted as true evidence [Hacking] |
| Full Idea: In the medieval view, evidence short of deduction was not really evidence at all. | |
| From: Ian Hacking (The Emergence of Probability [1975], Ch.3) | |
| A reaction: Hacking says the modern concept of evidence comes with probability in the 17th century. That might make it one of the most important ideas ever thought of, allowing us to abandon certainties and live our lives in a more questioning way. |
| 7451 | Formerly evidence came from people; the new idea was that things provided evidence [Hacking] |
| Full Idea: In the medieval view, people provided the evidence of testimony and of authority. What was lacking was the seventeenth century idea of the evidence provided by things. | |
| From: Ian Hacking (The Emergence of Probability [1975], Ch.4) | |
| A reaction: A most intriguing distinction, which seems to imply a huge shift in world-view. The culmination of this is Peirce's pragmatism, in Idea 6948, of which I strongly approve. |
| 583 | The starting point of a proof is not a proof [Aristotle] |
| Full Idea: Who defines the healthy man, or who is awake or asleep? This is a pursuit of foundations, but this is seeking an account where there isn't one. The starting point of a proof is not a proof. | |
| From: Aristotle (Metaphysics [c.324 BCE], 1011a10) | |
| A reaction: a comment on Descartes |
| 581 | Dreams aren't a serious problem. No one starts walking round Athens next morning, having dreamt that they were there! [Aristotle] |
| Full Idea: Is it really an issue whether things are true that appear to those asleep or to those awake? No one in Libya who dreamt he was in Athens, would set out for the Odeon next morning! | |
| From: Aristotle (Metaphysics [c.324 BCE], 1010b09) |
| 585 | If relativism is individual, how can something look sweet and not taste it, or look different to our two eyes? [Aristotle] |
| Full Idea: If things are true relative to an individual, how can something seem honey to the sight but not to the taste, or, given that we have two eyes, things may not seem the same to the sight of both of them. | |
| From: Aristotle (Metaphysics [c.324 BCE], 1011a24) |
| 584 | If truth is relative it is relational, and concerns appearances relative to a situation [Aristotle] |
| Full Idea: The claim that all appearances are true makes all things relational. Hence the claim is shifted to all appearances being true relative to a subject, time, sense and context. | |
| From: Aristotle (Metaphysics [c.324 BCE], 1011a20) | |
| A reaction: applies to Epicurus |
| 576 | If the majority had diseased taste, and only a few were healthy, relativists would have to prefer the former [Aristotle] |
| Full Idea: When two men taste the same thing one will often find it sweet and the other bitter. Suppose all men were sick, except one or two who were healthy. It would then be the latter two who would be considered sick, and the others not! | |
| From: Aristotle (Metaphysics [c.324 BCE], 1009b05) |
