In contrast with Gorgias and others, who boasted of possessing the art of making the small appear great, the great small, and of expatiating in long or short speeches, Prodicus required that the speech should be neither long nor short, but of the proper measure, and it is only as associated with other sophists that he is charged with endeavouring to make the weaker cause appear strong by means of his rhetoric.

In several of the Platonic dialogues Socrates appears as the friend and companion of Prodicus, which reveals at least that the two did have close personal relations, and that Socrates did attend at least a few of his lectures. "For Socrates, correct language was the prerequisite for correct living (including an efficient government). But Prodicus, though his linguistic teaching undoubtedly included semantic distinctions between ethical terms, had stopped at the threshold. The complete art of logoi embraced nothing less than the whole of philosophy."

. There appeared two women, the one of dignified beauty, adorned with purity, modesty, and discretion, the other of a voluptuous form, and meretricious look and dress. The latter promises to lead him by the shortest road, without any toil, to the enjoyment of every pleasure. The other, while she reminds him of his progenitors and his noble nature, does not conceal from him that the gods have not granted what is really beautiful and good apart from trouble and careful striving. While one seeks to deter him from the path of virtue by urging the difficulty of it; the other calls attention to the unnatural character of enjoyment which anticipates the need of it, its want of the highest joy, that arising from noble deeds, and the consequences of a life of voluptuousness, and how she herself, honoured by gods and men, leads to all noble works, and to true well-being in all circumstances of life. Hercules decides for virtue. This outline in Xenophon probably represents, in a very abbreviated form, the leading ideas of the original, of which no fragments remain.
