empirically
From LSJ
Έγ', ὦ ταλαίπωρ', αὐτὸς ὧν χρείᾳ πάρει. Τὰ πολλὰ γάρ τοι ῥήματ' ἢ τέρψαντά τι, ἢ δυσχεράναντ', ἢ κατοικτίσαντά πως, παρέσχε φωνὴν τοῖς ἀφωνήτοις τινά –> Wretched brother, tell him what you need. A multitude of words can be pleasurable, burdensome, or they can arouse pity somehow — they give a kind of voice to the voiceless.
English > Greek (Woodhouse)
adverb
to produce health and strength, not empirically, but on scientific principles: P. μὴ τριβῇ μόνον καὶ ἐμπειρίᾳ ἀλλὰ τέχνῃ… ὑγίειαν καὶ ῥώμην ἐμποιεῖν (Plato, Phaedrus 270B).
