21405 | Cicero sees wisdom in terms of knowledge, but earlier Stoics saw it as moral [Cicero, by Long] |
Full Idea: Cicero (drawing on Panaetius) treats wisdom as if its province were primarily a disinterested pursuit of knowledge. But earlier Stoics gave purely moral definitions of wisdom. | |
From: report of M. Tullius Cicero (On Duties ('De Officiis') [c.44 BCE], 1.11-20) by A.A. Long - Hellenistic Philosophy 5 | |
A reaction: I would have thought that after long discussion most ancient (and even modern) philosophers would conclude that it is both. The 'intellectualism' of Socrates hovers in the background, implying that healthy knowledge produces virtue. |
20871 | Unfortunately we choose a way of life before we are old enough to think clearly [Cicero] |
Full Idea: At the beginning of adolescence when our deliberative capacities are weak we decide on the way of life that we find attractive. So one gets entangled in a definite manner and pattern of life before one is able to judge which one is best. | |
From: M. Tullius Cicero (On Duties ('De Officiis') [c.44 BCE], 1.117) | |
A reaction: Hence it is important to have lots of means for bailing out of education courses, jobs, and even marriage. At least university postpones the key life choices till the early twenties. |
13166 | Essences are no use in mathematics, if all mathematical truths are necessary [Mancosu] |
Full Idea: Essences and essential properties do not seem to be useful in mathematical contexts, since all mathematical truths are regarded as necessary (though Kit Fine distinguishes between essential and necessary properties). | |
From: Paolo Mancosu (Explanation in Mathematics [2008], §6.1) | |
A reaction: I take the proviso in brackets to be crucial. This represents a distortion of notion of an essence. There is a world of difference between the central facts about the nature of a square and the peripheral inferences derivable from it. |
1799 | If we can't know minds, we can't know if Pyrrho was a sceptic [Theodosius, by Diog. Laertius] |
Full Idea: We can't say the school of Pyrrho is sceptical, because the motion of the mind in each individual is incomprehensible to others, so we don't know Pyrrho's disposition. | |
From: report of Theodosius (Chapters on Scepticism [c.100 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 09.Py.8 |
6031 | The essence of propriety is consistency [Cicero] |
Full Idea: The whole essence of propriety is quite certainly consistency. | |
From: M. Tullius Cicero (On Duties ('De Officiis') [c.44 BCE], 1.110) | |
A reaction: This seems to me the key intuition on which Kant built his deontological ethical theory. However, opponents say the consistency requires principles, and these are the enemies of truly good human behaviour, which involves Aristotle's 'particulars'. |
