8886 | Being a true justified belief is not a sufficient condition for knowledge [Gettier] |
Full Idea: The claim that someone knows a proposition if it is true, it is believed, and the person is justified in their belief is false, in that the conditions do not state a sufficient condition for the claim. | |
From: Edmund L. Gettier (Is Justified True Belief Knowledge? [1963], p.145) | |
A reaction: This is the beginning of the famous Gettier Problem, which has motivated most epistemology for the last forty years. Gettier implies that justification is necessary, even if it is not sufficient. He gives two counterexamples. |
10645 | We reach concepts by clarification, or by definition, or by habitual experience [Price,HH] |
Full Idea: We have three different ways in which we arrive at concepts or universals: there is a clarification, where we have a ready-made concept and define it; we have a combination (where a definition creates a concept); and an experience can lead to a habit. | |
From: H.H. Price (Review of Aron 'Our Knowledge of Universals' [1946], p.190) | |
A reaction: [very compressed] He cites Russell as calling the third one a 'condensed induction'. There seems to an intellectualist and non-intellectualist strand in the abstractionist tradition. |
10644 | A 'felt familiarity' with universals is more primitive than abstraction [Price,HH] |
Full Idea: A 'felt familiarity' with universals seems to be more primitive than explicit abstraction. | |
From: H.H. Price (Review of Aron 'Our Knowledge of Universals' [1946], p.188) | |
A reaction: This I take to be part of the 'given' of the abstractionist view, which is quite well described in the first instance by Aristotle. Price says that it is 'pre-verbal'. |
10646 | Our understanding of 'dog' or 'house' arises from a repeated experience of concomitances [Price,HH] |
Full Idea: Whether you call it inductive or not, our understanding of such a word as 'dog' or 'house' does arise from a repeated experience of concomitances. | |
From: H.H. Price (Review of Aron 'Our Knowledge of Universals' [1946], p.191) | |
A reaction: Philosophers don't use phrases like that last one any more. How else could we form the concept of 'dog' - if we are actually allowed to discuss the question of concept-formation, instead of just the logic of concepts. |
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. |
