ἐγὼ δ᾿ οὖν καὶ αὐτός, ὦ ᾿Αντιφῶν, ὥσπερ ἄλλος τις ἢ ἵππῳ ἀγαθῷ ἢ κυνὶ ἢ ὄρνιθι ἥδεται, οὕτω καὶ ἔτι μᾶλλον ἥδομαι φίλοις ἀγαθοῖς, καὶ ἐάν τι ἔχω ἀγαθόν, διδάσκω, καὶ ἄλλοις συνίστημι παρ᾿ ὧν ἂν ἡγῶμαι ὠφελήσεσθαί τι αὐτοὺς εἰς ἀρετήν· καὶ τοὺς θησαυροὺς τῶν πάλαι σοφῶν ἀνδρῶν, οὓς ἐκεῖνοι κατέλιπον ἐν βιβλίοις γράψαντες, ἀνελίττων κοινῇ σὺν τοῖς φίλοις διέρχομαι, καὶ ἄν τι ὁρῶμεν ἀγαθὸν, ἐκλεγόμεθα· καὶ μέγα νομίζομεν κέρδος, ἐὰν ἀλλήλοις φίλοι γιγνώμεθα. [ Memorabilia (Xenophon) A, 6, 12 ]
In accordance with this theory, I too, Antiphon, having my tastes, even as another finds pleasure in his horse and his hounds, and another in his fighting cocks, so I too take my pleasure in good friends; and if I have any good thing myself I teach it them, or I commend them to others by whom I think they will be helped forwards on the path of virtue. The treasures also of the wise of old, written and bequeathed in their books, I unfold and peruse in common with my friends. If our eye light upon any good thing we cull it eagerly, and regard it as great gain if we may but grow in friendship with one another. [ ***The Project Gutenberg Etext of The Memorabilia by Xenophon*** Translation by H. G. Dakyns ]
Ἐὰν ταῖς γλώσσαις τῶν ἀνθρώπων λαλῶ καὶ τῶν ἀγγέλων, ἀγάπην δὲ μὴ ἔχω, γέγονα χαλκὸς ἠχῶν ἢ κύμβαλον ἀλαλάζον. καὶ ἐὰν ἔχω προφητείαν καὶ εἰδῶ τὰ μυστήρια πάντα καὶ πᾶσαν τὴν γνῶσιν, καὶ ἐὰν ἔχω πᾶσαν τὴν πίστιν, ὥστε ὄρη μεθιστάνειν, ἀγάπην δὲ μὴ ἔχω, οὐδέν εἰμι. καὶ ἐὰν ψωμίσω πάντα τὰ ὑπάρχοντά μου, καὶ ἐὰν παραδῶ τὸ σῶμά μου ἵνα καυθήσομαι, ἀγάπην δὲ μὴ ἔχω, οὐδὲν ὠφελοῦμαι. [ Α’ Ἐπιστολὴ Παύλου πρὸς Κορινθίους (ιγ’ 1-3) ]
If I speak in the tongues of men and of angels, but have not love, I am a noisy gong or a clanging cymbal. And if I have prophetic powers, and understand all mysteries and all knowledge, and if I have all faith, so as to remove mountains, but have not love, I am nothing. If I give away all I have, and if I deliver my body to be burned, but have not love, I gain nothing. [ St. Paul's First Letter to the Corinthians (ιγ’ 1-3) ]
