Modern scholars have detected a polemic between Speusippus and Eudoxus of Cnidus concerning the good. Eudoxus also accepts that the Good will be that at which all people aim, but identifies this as pleasure, as opposed to Speusippus' exclusive focus on moral goods. Texts of Aristotle and Aulus Gellius suggest that Speusippus insisted that pleasure was not a good, but that the Good was "in between the opposites of pleasure and pain." It is possible that the dispute between Speusippus and Eudoxus influenced Plato's "Philebus" (esp. 53c–55a).
