3 ideas
| 23217 | All of our happiness and misery arises entirely from the brain [Hippocrates] |
| Full Idea: Men ought to know that from the brain, and from the brain alone, arise our pleasures, joys, laughter and jests, as well as our sorrow, pains, griefs and tears. | |
| From: Hippocrates (Hippocrates of Cos on the mind [c.430 BCE], p.32) | |
| A reaction: If this could be assertedly so confidently at that date, why was the fact so slow to catch on? Brain injuries should have convinced everyone. |
| 6005 | Animals are dangerous and nourishing, and can't form contracts of justice [Hermarchus, by Sedley] |
| Full Idea: Hermarchus said that animal killing is justified by considerations of human safety and nourishment and by animals' inability to form contractual relations of justice with us. | |
| From: report of Hermarchus (fragments/reports [c.270 BCE]) by David A. Sedley - Hermarchus | |
| A reaction: Could the last argument be used to justify torturing animals? Or could we eat a human who was too brain-damaged to form contracts? |
| 20919 | How can things without weight compose weight? [Alexander] |
| Full Idea: How could weight come about out of things composed of what is without weight? | |
| From: Alexander (On Aristotle's Metaphysics Book 2 [c.200], p.36.21-27) | |
| A reaction: This is obviously why Epicurus added weight to the features of atoms. Alexander seems unaware of this move. |
