5. Theory of Logic / A. Overview of Logic / 3. Value of Logic
10152 Set theory and logic are fairy tales, but still worth studying [Tarski]
     Full Idea: People have asked me, 'How can you, a nominalist, do work in set theory and in logic, which are theories about things you do not believe in?' ...I believe that there is a value even in fairy tales and the study of fairy tales.
     From: Alfred Tarski (talk [1965]), quoted by Feferman / Feferman - Alfred Tarski: life and logic
     A reaction: This is obviously an oversimplification. I don't think for a moment that Tarski literally believed that the study of fairy tales had as much value as the study of logic. Why do we have this particular logic, and not some other?
8. Modes of Existence / E. Nominalism / 1. Nominalism / a. Nominalism
10151 I am a deeply convinced nominalist [Tarski]
     Full Idea: I am a nominalist. This is a very deep conviction of mine. ...I am a tortured nominalist.
     From: Alfred Tarski (talk [1965]), quoted by Feferman / Feferman - Alfred Tarski: life and logic Int I
     A reaction: I too am of the nominalist persuasion, but I don't feel justified in such a strong commitment.
14. Science / C. Induction / 5. Paradoxes of Induction / a. Grue problem
7296 'Grue' is not a colour [Milsted]
     Full Idea: 'Grue' is not a colour.
     From: Tom Milsted (talk [2006]), quoted by PG - Db (ideas)
     A reaction: This simple observation strikes me as rather crucial in assessing Goodman's paradox. Blue is a colour, but grue is some sort of behaviour. Blue is a secondary quality, but grue seems to be a primary quality.
23. Ethics / C. Virtue Theory / 3. Virtues / a. Virtues
7903 The six perfections are giving, morality, patience, vigour, meditation, and wisdom [Nagarjuna]
     Full Idea: The six perfections are of giving, morality, patience, vigour, meditation, and wisdom.
     From: Nagarjuna (Mahaprajnaparamitashastra [c.120], 88)
     A reaction: What is 'morality', if giving is not part of it? I like patience and vigour being two of the virtues, which immediately implies an Aristotelian mean (which is always what is 'appropriate').
