Theophrastus

"Συνεχές τε … πολυτελὲς ἀνάλωμα εἶναι τὸν χρόνον."

"The Unseasonable man is one who will go up to a busy person, and open his heart to him. He will serenade his mistress when she has a fever. He will address himself to a man who has been cast in a surety-suit, and request him to become his security. He will come to give evidence when the trial is over."

"Superstition would seem to be simply cowardice in regard to the supernatural."

"Εἰ μὲν ἀμαθὴς εἶ, φρονίμως ποιεῖς, εἰ δὲ πεπαίδευσαι, ἀφρόνως."

"Ἐπισκήπτειν μὲν ἔχειν οὐδέν, πλὴν ὅτι πολλὰ τῶν ἡδέων ὁ βίος διὰ τὴν δόξαν καταλαζονεύεται. Ἡμεῖς γὰρ ὁπότ' ἀρχόμεθα ζῆν, τότ' ἀποθνῄσκομεν. Οὐδὲν οὖν ἀλυσιτελέστερόν ἐστι φιλοδοξίας."

"Aristotle having declaimed irreverently of the gods, and dreading the fate of Socrates, wished to retire from Athens. In a beautiful manner he pointed out his successor. There were two rivals in his schools: Menedemus the Rhodian, and Theophrastus of Lesbos. Alluding delicately to his own critical situation, he told his assembled scholars that the wine he was accustomed to drink was injurious to him, and he desired them to bring the wines of Rhodes and Lesbos. He tasted both, and declared they both did honour to their soil, each being excellent, though differing in their quality;—the Rhodian wine is the strongest, but the Lesbian is the sweetest, and that he himself preferred it. Thus his ingenuity designated his favourite Theophrastus, the author of the "Characters," for his successor."

"Theophrastus of Eresus... wrote a book On Winds and on Weather Signs, but like most other Greek philosophers, he was hardly the man to adopt patient and exact observation in place of dogmatic assertion and the teaching of authority."
