Αριστοτέλους- Ηθικά

Ἕκαστος δὲ κρίνει καλῶς ἃ γινώσκει, καὶ τούτων ἐστὶν ἀγαθὸς κριτής. καθ᾽ ἕκαστον μὲν ἄρα ὁ πεπαιδευμένος, ἁπλῶς δ᾽ ὁ περὶ πᾶν πεπαιδευμένος. διὸ τῆς πολιτικῆς οὐκ ἔστιν οἰκεῖος ἀκροατὴς ὁ νέος· ἄπειρος γὰρ τῶν κατὰ τὸν βίον πράξεων, οἱ λόγοι δ᾽ ἐκ τούτων καὶ περὶ τούτων· ἔτι δὲ τοῖς πάθεσιν ἀκολουθητικὸς ὢν ματαίως ἀκούσεται καὶ ἀνωφελῶς, ἐπειδὴ τὸ τέλος ἐστὶν οὐ γνῶσις ἀλλὰ πρᾶξις.

Now each man judges well the things he knows, and of these he is a good judge. And so the man who has been educated in a subject is a good judge of that subject, and the man who has received an all-round education is a good judge in general. Hence a young man is not a proper hearer of lectures on political science; for he is inexperienced in the actions that occur in life, but its discussions start from these and are about these; and, further, since he tends to follow his passions, his study will be vain and unprofitable, because the end aimed at is not knowledge but action.

διαφέρει δ᾽ οὐδὲν νέος τὴν ἡλικίαν ἢ τὸ ἦθος νεαρός· οὐ γὰρ παρὰ τὸν χρόνον ἡ ἔλλειψις, ἀλλὰ διὰ τὸ κατὰ πάθος ζῆν καὶ διώκειν ἕκαστα.

And it makes no difference whether he is young in years or youthful in character; the defect does not depend on time, but on his living, and pursuing each successive object, as passion directs.

τοῖς γὰρ τοιούτοις ἀνόνητος ἡ γνῶσις γίνεται, καθάπερ τοῖς ἀκρατέσιν· τοῖς δὲ κατὰ λόγον τὰς ὀρέξεις ποιουμένοις καὶ πράττουσι πολυωφελὲς ἂν εἴη τὸ περὶ τούτων εἰδέναι.

For to such persons, as to the incontinent, knowledge brings no profit; but to those who desire and act in accordance with a rational principle knowledge about such matters will be of great benefit.

Για όσους βιάζονται να εισαγάγουν την μικροπολιτική στα σχολεία, για τους σκοπούς τους οποίους όλοι γνωρίζουμε.
