10190 | From the axiomatic point of view, mathematics is a storehouse of abstract structures [Bourbaki] |
Full Idea: From the axiomatic point of view, mathematics appears as a storehouse of abstract forms - the mathematical structures. | |
From: Nicholas Bourbaki (The Architecture of Mathematics [1950], 221-32), quoted by Fraser MacBride - Review of Chihara's 'Structural Acc of Maths' p.79 | |
A reaction: This seems to be the culmination of the structuralist view that developed from Dedekind and Hilbert, and was further developed by philosophers in the 1990s. |
6027 | From the fact that some men die, we cannot infer that they all do [Philodemus] |
Full Idea: There is no necessary inference, from the fact that men familiar to us die when pierced through the heart, that all men do. | |
From: Philodemus (On Signs (damaged) [c.50 BCE], 1.3) | |
A reaction: This is scepticism about the logic of induction, long before David Hume. This is said to be a Stoic argument against Epicureans - though on the whole Stoics are not keen on scepticism. |
22241 | Don't fear god or worry about death; the good is easily got and the terrible easily cured [Philodemus] |
Full Idea: Don't fear god, Don't worry about death; What is good is easy to get, What is terrible is easy to cure. | |
From: Philodemus (Herculaneum Papyrus [c.50 BCE], 1005,4.9-14) | |
A reaction: This is known as the Four-Part Cure, and is an epicurean prayer, probably formulated by Epicurus. |
15314 | Faraday's single field of variable forces introduces a criterion of Unity into what is ultimate [Faraday, by Harré/Madden] |
Full Idea: In Faraday lines of force picture the directional structure of powers,...so the fundamental entity is a single, unified field. ...A new criterion of the ultimate has stepped in: Unity. The universal field is still the final explanation, but not invariant. | |
From: report of Michael Faraday (Experimental Researches in Electricity [1859]) by Harré,R./Madden,E.H. - Causal Powers 9.II.B | |
A reaction: Almost Parmenides, except that the field is not invariant. But that was always the ancient objection to the One - that it offered no explanation of change. |
