9807 | In pursuing truth, anything less certain than mathematics is a waste of time [Descartes] |
Full Idea: In our search for the direct road towards truth we should busy ourselves with no object about which we cannot attain a certitude equal to that of the demonstrations of Arithmetic and Geometry. | |
From: René Descartes (Rules for the Direction of the Mind [1628], Rule II), quoted by Alain Badiou - Mathematics and Philosophy: grand and little p.8 | |
A reaction: A beautiful statement of the way in which rationalist philosophy was founded on the model of mathematics (esp. Euclid), with all its concomitant problems. The most important concept of the last hundred years may well be fallibilist rationalism. |
468 | Musical performance can reveal a range of virtues [Damon of Ath.] |
Full Idea: In singing and playing the lyre, a boy will be likely to reveal not only courage and moderation, but also justice. | |
From: Damon (fragments/reports [c.460 BCE], B4), quoted by (who?) - where? |
22230 | Sartre gradually realised that freedom is curtailed by the weight of situation [Sartre, by Daigle] |
Full Idea: Sartre evolved from a notion of absolute freedom to one that truly takes into account the weight of situation. | |
From: report of Jean-Paul Sartre (works [1950]) by Christine Daigle - Jean-Paul Sartre 2.3 | |
A reaction: This change seems to have come much later, in the 1960s. The main influence seems to have been Marxism, which claims that consciousness is created by society, rather than by free individuals. |
