22512 | Acts are voluntary if done knowingly, by the agent, and in his power to avoid it [Aristotle] |
Full Idea: Whatever a man does - not in ignorance, and through his own agency - when it is in his power not to do it, must be voluntary, and that is what voluntary is. | |
From: Aristotle (Eudemian Ethics [c.333 BCE], 1225b08) | |
A reaction: This is the conclusion of the Eudemian discussion of responsibility. This is a definition by necessary and sufficient conditions. How can you be sure that something is in your power not to do? |
22509 | What is natural for us is either there at birth, or appears by normal processes [Aristotle] |
Full Idea: By these marks we distinguish what comes naturally: everything that is there straightaway as soon as something comes to be, and all that occurs to us if growth is allowed to proceed normally - such as greying hair, ageing, and the like. | |
From: Aristotle (Eudemian Ethics [c.333 BCE], 1224b32) | |
A reaction: The word 'normal' has to do a lot of work here. Presumably jaundice in a neonate is not included. Or later hereditary diseases. |
20841 | Zeno said live in agreement with nature, which accords with virtue [Zeno of Citium, by Diog. Laertius] |
Full Idea: Zeno first (in his book On Human Nature) said that the goal was to live in agreement with nature, which is to live according to virtue. | |
From: report of Zeno (Citium) (fragments/reports [c.294 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.87 | |
A reaction: The main idea seems to be Aristotelian - that the study of human nature reveals what our virtues are, and following them is what nature requires. Nature is taken to be profoundly rational. |
1774 | Since we are essentially rational animals, living according to reason is living according to nature [Zeno of Citium, by Diog. Laertius] |
Full Idea: As reason is given to rational animals according to a more perfect principle, it follows that to live correctly according to reason, is properly predicated of those who live according to nature. | |
From: report of Zeno (Citium) (fragments/reports [c.294 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.Ze.52 | |
A reaction: This is the key idea for understanding what the stoics meant by 'live according to nature'. The modern idea of rationality doesn't extend to 'perfect principles', however. |
