[954] Even with his limited outlook Aristotle had sufficient astuteness to divine that nature might become the “slave of man,” and expresses himself clearly to that effect; Metaphysics, i, 2.

Ἐχθρὸς γάρ μοι κεῖνος ὁμως Αἰδᾶο πύλησιν,

Iliad, ix, 312.

Ἔργον δ’ οὐδὲν ὄνειδος, ἀεργίη δέ τ’ ὄνειδος.

Op. et Dies, 311.

Μὴ κακὰ κερδαίνειν, κακὰ κέρδεα ἷσ’ ἄτῃσιν.

Ibid., 352.
