4 ideas

1. Philosophy / D. Nature of Philosophy / 4. Divisions of Philosophy
Three branches of philosophy: first logic, second ethics, third physics (which ends with theology) [Chrysippus]
     Full Idea: There are three kinds of philosophical theorems, logical, ethical, and physical; of these the logic should be placed first, ethics second, and physics third (and theology is the final topic in physics).
     From: Chrysippus (fragments/reports [c.240 BCE]), quoted by Plutarch - 70: Stoic Self-contradictions 1035a
     A reaction: [in his lost 'On Lives' Bk 4] 'Theology is the final topic in physics'! That should create a stir in theology departments. Is this an order of study, or of importance? You come to theology right at the end of your studies.
Stoic physics concerns cosmos, elements and causes (with six detailed divisions) [Stoic school, by Diog. Laertius]
     Full Idea: Stoics divide physics into topics on bodies, principles, elements, gods, limits, place and void. The general division is into three topics, concerning the cosmos, the elements and causal explanations.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.132
     A reaction: Apart from the gods, not much has changed.
Ethics studies impulse, good, passion, virtue, goals, value, action, appropriateness, encouragement [Stoic school, by Diog. Laertius]
     Full Idea: Stoic divisions of ethics: on impulse, on good and bad things, on passions, on virtue, on the goal, on primary value, on actions, on appropriate actions, and on encouragements and discouragements to action.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.84
     A reaction: A substantial part of this is covered by modern Action Theory, rather than by ethics. This describes later stoicism, from Chrysippus onwards. I like the study of 'appropriate actions', which could do with some modern analysis.
1. Philosophy / D. Nature of Philosophy / 5. Aims of Philosophy / a. Philosophy as worldly
True philosophising is not memorising ideas, but living by them [Stoic school, by Stobaeus]
     Full Idea: It is not the man who listens eagerly and memorises what philosophers say who is prepared for philosophising, but the man who is prepared to carry into action what is pronounced in philosophy and to live by it.
     From: report of Stoic school (fragments/reports [c.200 BCE]) by John Stobaeus - Anthology 2.11k
     A reaction: Hence stoicism was seen more as a way of life, and less as theorising. I aim to combine the two. There is a way of life which centres on theorising about life while living it. A life without enquiry is not worth living.
