Plato, Laws 902c

τοῖς θεοῖς· οὐδετέρως γὰρ τοῖς κεκτημένοις ἡμᾶς ἀμελεῖν ἂν εἴη προσῆκον, ἐπιμελεστάτοις γε οὖσι καὶ ἀρίστοις. σκοπῶμεν γὰρ δὴ καὶ τόδε ἔτι πρὸς τούτοις. τὸ ποῖον; τὸ περί τε αἰσθήσεως καὶ δυνάμεως, ἆρʼ οὐκ ἐναντίως ἀλλήλοιν πρὸς ῥᾳστώνην καὶ χαλεπότητά ἐστον πεφυκότε; πῶς λέγεις; ὁρᾶν μέν που καὶ ἀκούειν τὰ σμικρὰ χαλεπώτερον ἢ τὰ μεγάλα, φέρειν δὲ αὖ καὶ κρατεῖν καὶ ἐπιμελεῖσθαι τῶν σμικρῶν καὶ ὀλίγων παντὶ ῥᾷον ἢ τῶν ἐναντίων.

in the eyes of the gods; for in neither case would it behove those who are our owners to be neglectful, seeing that they are most careful and most good. For let us notice this further fact— What is it? In regard to perception and power,—are not these two naturally opposed in respect of ease and difficulty? How do you mean? It is more difficult to see and hear small things than great; but everyone finds it more easy to move, control and care for things small and few than their opposites.
