Quote from Diogenes Laertius 10.34 (The Feelings as the Third Criterion)The internal sensations they say are two, pleasure and pain, which occur to every living creature, and the one is akin to nature and the other alien: by means of these two choice and avoidance are determined. Of inquiries some are concerned with things and some with nothing but words. (Bailey)
