| 3644 | Two things being joined together doesn't prove they are the same [Descartes] |
| Full Idea: The fact that we often see two things joined together does not license the inference that they are one and the same. | |
| From: René Descartes (Reply to Sixth Objections [1641], 444) | |
| A reaction: Correct. The problem comes when they are never ever apart, and you begin to suspect that they are conjoined in all possible worlds. Why might this be so? It can only be identity or a causal link. |
| 3621 | Only judgement decides which of our senses are reliable [Descartes] |
| Full Idea: Sense alone does not suffice to correct visual error: we also need a degree of reason to tell us that we should believe the judgement based on touch rather than vision. Since we don't have this power in infancy, it must be attributed to the intellect. | |
| From: René Descartes (Reply to Sixth Objections [1641], 439) |
| 20740 | Maybe humans are distinguished from other animals by feelings, rather than reason [Unamuno] |
| Full Idea: Man is said to be a reasoning animal. I do not know why he has not been defined as an affective or feeling animal. Perhaps that which differentiates him from other animals is feeling rather than reason. | |
| From: Miguel de Unamuno (The Tragic Sense of Life [1912], p.3), quoted by Kevin Aho - Existentialism: an introduction 2 'Problem' | |
| A reaction: Perfectly plausible, given that we presume that our feelings are startlingly different from other animals - even if we feel far more community with other mammals than we did in Unamuno's day. |
| 13304 | Learned men gain more in one day than others do in a lifetime [Posidonius] |
| Full Idea: In a single day there lies open to men of learning more than there ever does to the unenlightened in the longest of lifetimes. | |
| From: Posidonius (fragments/reports [c.95 BCE]), quoted by Seneca the Younger - Letters from a Stoic 078 | |
| A reaction: These remarks endorsing the infinite superiority of the educated to the uneducated seem to have been popular in late antiquity. It tends to be the religions which discourage great learning, especially in their emphasis on a single book. |
| 20820 | Time is an interval of motion, or the measure of speed [Posidonius, by Stobaeus] |
| Full Idea: Posidonius defined time thus: it is an interval of motion, or the measure of speed and slowness. | |
| From: report of Posidonius (fragments/reports [c.95 BCE]) by John Stobaeus - Anthology 1.08.42 | |
| A reaction: Hm. Can we define motion or speed without alluding to time? Looks like we have to define them as a conjoined pair, which means we cannot fully understand either of them. |
| 3637 | Ideas in God's mind only have value if he makes it so [Descartes] |
| Full Idea: It is impossible to imagine that anything is thought of in the divine intellect as good or true, or worthy of belief or action or omission, prior to the decision of the divine will to make it so. | |
| From: René Descartes (Reply to Sixth Objections [1641], 432) |
