"Demetrius the grammarian finding in the temple of Delphos a knot of philosophers set chatting together, said to them, "Either I am much deceived,or by your cheerful and pleasant countenances, you are engaged in no very deep discourse. To which one of them, Heracleon the Megarean, replied: " 'Tis for such as are puzzled about inquiring whether the future tense of the verb Ballo be spelt with adouble L, or that hunt after the derivation of the comparatives Cheirou and Beltiou, and the superlatives Cheiriotou and Beliotou, to knit their brows whilst discoursing of their science; but as to philosophical discourses, they always divert and cheer up those that entertain them, and never deject them or make them sad."
