304 | Beautiful things must be different from beauty itself, but beauty itself must be present in each of them [Plato] |
Full Idea: Are fine things different from or identical to fineness? They are different from fineness itself, but fineness itself is in a sense present in each of them. | |
From: Plato (Euthydemus [c.379 BCE], 301a) |
16120 | Knowing how to achieve immortality is pointless without the knowledge how to use immortality [Plato] |
Full Idea: If there exists the knowledge of how to make men immortal, but without the knowledge of how to use this immortality, there seems to be no value in it. | |
From: Plato (Euthydemus [c.379 BCE], 289b) | |
A reaction: I take this to be not a gormless utilitarianism about knowledge, but a plea for holism, that knowledge only has value as part of some larger picture. The big view is the important view. He's wrong, though. Work out the use later. |
19699 | A Gettier case is a belief which is true, and its fallible justification involves some luck [Hetherington] |
Full Idea: A Gettier case contains a belief which is true and well justified without being knowledge. Its justificatory support is also fallible, ...and there is considerable luck in how the belief combnes being true with being justified. | |
From: Stephen Hetherington (The Gettier Problem [2011], 5) | |
A reaction: This makes luck the key factor. 'Luck' is a rather vague concept, and so the sort of luck involved must first be spelled out. Or the varieties of luck that can produce this outcome. |
303 | Say how many teeth the other has, then count them. If you are right, we will trust your other claims [Plato] |
Full Idea: If each of you says how many teeth the other has, and when they are counted we find you do know, we will believe your other claims as well. | |
From: Plato (Euthydemus [c.379 BCE], 294c) | |
A reaction: This is the clairvoyant problem for reliabilism, if truth is delivered for no apparent reason. Useful, but hardly knowledge. HOW did you know the number of teeth? |
302 | What knowledge is required to live well? [Plato] |
Full Idea: What knowledge would enable us to live finely for the rest of our lives? | |
From: Plato (Euthydemus [c.379 BCE], 293a) | |
A reaction: A successful grasp of other people's points of view might lead to respect for them. Also a realisation that we are not isolated individuals. We really are all in it together. |
301 | Only knowledge of some sort is good [Plato] |
Full Idea: Nothing is good except knowledge of some sort. | |
From: Plato (Euthydemus [c.379 BCE], 292b) | |
A reaction: I've heard it suggested that truth is the only value. This is the Socratic idea that moral goodness is a matter of successful rational judgement. Not convinced, but interesting. |
305 | Something which lies midway between two evils is better than either of them [Plato] |
Full Idea: Something which is composed of two factors which are bad for different purposes and lies midway between them is better than either of the factors. | |
From: Plato (Euthydemus [c.379 BCE], 306a) |
1748 | Archelaus was the first person to say that the universe is boundless [Archelaus, by Diog. Laertius] |
Full Idea: Archelaus was the first person to say that the universe is boundless. | |
From: report of Archelaus (fragments/reports [c.450 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 02.Ar.3 |
5989 | Archelaus said life began in a primeval slime [Archelaus, by Schofield] |
Full Idea: Archelaus wrote that life on Earth began in a primeval slime. | |
From: report of Archelaus (fragments/reports [c.450 BCE]) by Malcolm Schofield - Archelaus | |
A reaction: This sounds like a fairly clearcut assertion of the production of life by evolution. Darwin's contribution was to propose the mechanism for achieving it. We should honour the name of Archelaus for this idea. |
