1. Philosophy / A. Wisdom / 1. Nature of Wisdom
Wisdom for one instant is as good as wisdom for eternity [Chrysippus]
     Full Idea: If a person has wisdom for one instant, he is no less happy than he who possesses it for eternity.
     From: Chrysippus (fragments/reports [c.240 BCE]), quoted by Pierre Hadot - Philosophy as a way of life 8
     A reaction: [Hadot quotes Plutarch 'On Common Conceptions' 8,1062a] This makes it sound awfully like some sort of Buddhist 'enlightenment', which strikes like lightning. He does wisdom recognise itself - by a warm glow, or by the cautious thought that got you there?
Wisdom is knowing the highest good, and conforming the will to it [Kant]
     Full Idea: Wisdom, theoretically regarded, means the knowledge of the highest good and, practically, the conformability of the will to the highest good.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.II.II.V)
     A reaction: This seems a narrow account of wisdom, focusing entirely on goodness rather than truth. A mind that valued nothing but understood everything would have a considerable degree of wisdom, in the normal use of that word.
1. Philosophy / A. Wisdom / 2. Wise People
Wise men should try to participate in politics, since they are a good influence [Chrysippus, by Diog. Laertius]
     Full Idea: The wise man will participate in politics unless something prevents him, for he will restrain vice and promote virtue.
     From: report of Chrysippus (fragments/reports [c.240 BCE]) by Diogenes Laertius - Lives of Eminent Philosophers 07.121
     A reaction: [from lost On Ways of Life Bk 1] We have made modern politics so hostile for its participants, thanks to cruel media pressure, that the best people now run a mile from it. Disastrous.
1. Philosophy / D. Nature of Philosophy / 3. Philosophy Defined
What fills me with awe are the starry heavens above me and the moral law within me [Kant]
     Full Idea: Two things fill the mind with ever new and increasing wonder and awe, the oftener and the more steadily we reflect on them: the starry heavens above me and the moral law within me.
     From: Immanuel Kant (Critique of Practical Reason [1788], Concl)
     A reaction: I am beginning to think that the two major issues of all philosophy are ontology and metaethics, and Kant is close to agreeing with me. He certainly wasn't implying that astronomy was a key aspect of philosophy.
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.
1. Philosophy / D. Nature of Philosophy / 5. Aims of Philosophy / e. Philosophy as reason
Consistency is the highest obligation of a philosopher [Kant]
     Full Idea: Consistency is the highest obligation of a philosopher and yet the most rarely found.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.1.1.§3)
     A reaction: I agree with this, and it also strikes me as the single most important principle of Kant's philosophy, which is the key to his whole moral theory.
1. Philosophy / E. Nature of Metaphysics / 5. Metaphysics beyond Science
Metaphysics is just a priori universal principles of physics [Kant]
     Full Idea: Metaphysics only contains the pure a priori principles of physics in their universal import.
     From: Immanuel Kant (Critique of Practical Reason [1788], I.II.II.VI)
     A reaction: 'Universal' seems to imply 'necessary'. If you thought that no a priori universal principles were possible, you would be left with physics. I quite like the definition, except that I think there would still be metaphysics even if there were no physics.
