17809 | Gödel showed that the syntactic approach to the infinite is of limited value [Kreisel] |
Full Idea: Usually Gödel's incompleteness theorems are taken as showing a limitation on the syntactic approach to an understanding of the concept of infinity. | |
From: Georg Kreisel (Hilbert's Programme [1958], 05) |
17810 | The study of mathematical foundations needs new non-mathematical concepts [Kreisel] |
Full Idea: It is necessary to use non-mathematical concepts, i.e. concepts lacking the precision which permit mathematical manipulation, for a significant approach to foundations. We currently have no concepts of this kind which we can take seriously. | |
From: Georg Kreisel (Hilbert's Programme [1958], 06) | |
A reaction: Music to the ears of any philosopher of mathematics, because it means they are not yet out of a job. |
20751 | As a young girl assumes her status as feminine, she acts in a more fragile immobile way [Young,IM] |
Full Idea: The young girl acquires many subject habits of feminine body comportment - walking, tilting her head, standing and sitting like a girl, and so on ….The more a girl assumes her status as feminine, the more she takes herself to be fragile and immobile. | |
From: Iris Marion Young (On Female Body Experience [2005], p.43), quoted by Kevin Aho - Existentialism: an introduction 3 'Aspects' | |
A reaction: This strikes me as true of young women, but it largely wears off as they get older, at least among modern women. A whole book could be written about women and smiling. |
17811 | The natural conception of points ducks the problem of naming or constructing each point [Kreisel] |
Full Idea: In analysis, the most natural conception of a point ignores the matter of naming the point, i.e. how the real number is represented or by what constructions the point is reached from given points. | |
From: Georg Kreisel (Hilbert's Programme [1958], 13) | |
A reaction: This problem has bothered me. There are formal ways of constructing real numbers, but they don't seem to result in a name for each one. |
1513 | The Egyptians were the first to say the soul is immortal and reincarnated [Herodotus] |
Full Idea: The Egyptians were the first to claim that the soul of a human being is immortal, and that each time the body dies the soul enters another creature just as it is being born. | |
From: Herodotus (The Histories [c.435 BCE], 2.123.2) |
