6 ideas
| 3653 | My Meditations are the complete foundation of my physics [Descartes] |
| Full Idea: My six Meditations contain all the foundations of my physics, …and their principles destroy those of Aristotle. | |
| From: René Descartes (Letters to Mersenne [1640], 1641.01.28) |
| 4736 | Truth is such a transcendentally clear notion that it cannot be further defined [Descartes] |
| Full Idea: Truth is such a transcendentally clear notion that it cannot be further defined. | |
| From: René Descartes (Letters to Mersenne [1640], 1642), quoted by Pascal Engel - Truth Intro | |
| A reaction: This is the view endorsed by Davidson. It is tempting to take basic concepts as axiomatic, but philosophers can't make that move every time they are in trouble. I have to say, though, that truth is a good candidate. |
| 16597 | Quantity is the capacity to be divided [Digby] |
| Full Idea: Quantity …is divisibility, or a capacity to be divided into parts. | |
| From: Kenelm Digby (Two treatises [1644], I.2.8), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 04.1 | |
| A reaction: 'Quantity' is scholastic philosophy is a concept we no longer possess. Without quantity, a thing might potentially exist at a spaceless point. Quantity is what spreads things out. See Pasnau Ch. 4. |
| 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? |
| 16731 | Colours arise from the rarity, density and mixture of matter [Digby] |
| Full Idea: The origin of all colours in bodies is plainly deduced out of the various degrees of rarity and density, variously mixed and compounded. | |
| From: Kenelm Digby (Two treatises [1644], I.29.4), quoted by Robert Pasnau - Metaphysical Themes 1274-1671 22.5 | |
| A reaction: We are still struggling with this question, though I think the picture is gradually become clear, once you get the hang of the brain. Easy! See Idea 17396. |
| 3652 | I can't prove the soul is indestructible, only that it is separate from the mortal body [Descartes] |
| Full Idea: I don't know how to demonstrate that God cannot annihilate the soul, but only that it is entirely distinct from the body, and consequently that it is not naturally subject to die with it, which is all that is required to establish religion. | |
| From: René Descartes (Letters to Mersenne [1640], 1640.02.24) |
