Plato, Laws 645e

τί δʼ αὖ τὰς αἰσθήσεις καὶ μνήμας καὶ δόξας καὶ φρονήσεις; πότερον ὡσαύτως σφοδροτέρας; ἢ πάμπαν ἀπολείπει ταῦτα αὐτόν, ἂν κατακορής τις τῇ μέθῃ γίγνηται; ναί, πάμπαν ἀπολείπει. οὐκοῦν εἰς ταὐτὸν ἀφικνεῖται τὴν τῆς ψυχῆς ἕξιν τῇ τότε ὅτε νέος ἦν παῖς; τί μήν; ἥκιστα δὴ τότʼ ἂν αὐτὸς αὑτοῦ γίγνοιτο ἐγκρατής.

And how about sensations and recollections and opinions and thoughts? Does it make them likewise more intense? Or rather, do not these quit a man entirely if he becomes surfeited with drink? Yes, they quit him entirely. He then arrives at the same condition of soul as when he was a young child? He does. So at that moment he will have very little control of himself?
