3 ideas

1. Philosophy / D. Nature of Philosophy / 3. Philosophy Defined

23367	Even pointing a finger should only be done for a reason [Epictetus]
	Full Idea: Philosophy says it is not right even to stretch out a finger without some reason.
	From: Epictetus (fragments/reports [c.57], 15)
	A reaction: The key point here is that philosophy concerns action, an idea on which Epictetus is very keen. He rather despise theory. This idea perfectly sums up the concept of the wholly rational life (which no rational person would actually want to live!).

5. Theory of Logic / K. Features of Logics / 1. Axiomatisation

16886	The truth of an axiom must be independently recognisable [Frege]
	Full Idea: It is part of the concept of an axiom that it can be recognised as true independently of other truths.
	From: Gottlob Frege (On Euclidean Geometry [1900], 183/168), quoted by Tyler Burge - Frege on Knowing the Foundations 4
	A reaction: Frege thinks the axioms of arithmetic all reside in logic.

20. Action / B. Preliminaries of Action / 2. Willed Action / d. Weakness of will

22511	Some reasonings are stronger than we are [Philolaus]
	Full Idea: Some reasonings are stronger than we are.
	From: Philolaus (fragments/reports [c.425 BCE]), quoted by Aristotle - Eudemian Ethics 1225a33
	A reaction: This endorses the Aristotle view of akrasia (as opposed to the Socratic view). This isolated remark seems to imply that we are more clearly embodiments of will than of reason.
