§5.19.1Τὰ πράγματα αὐτὰ οὐδ’ ὁπωστιοῦν ψυχῆς ἅπτεται οὐδὲ ἔχει εἴσοδον πρὸς ψυχὴν οὐδὲ τρέψαι οὐδὲ κινῆσαι ψυχὴν δύναται, τρέπει δὲ καὶ κινεῖ αὐτὴ ἑαυτὴν μόνη καὶ οἵων ἂν κριμάτων καταξιώσῃ ἑαυτήν, τοιαῦτα ἑαυτῇ ποιεῖ τὰ προσυφεστῶτα.
Things themselves do not touch the soul in the least, nor have they any access to the soul, nor can they turn or move the soul; but the soul alone turns and moves itself, and according as it deems itself worthy of what judgments, so it makes the things which present themselves conform to those judgments.
