Tisias of Syracus (5th cent. bce), teacher of rhetoric, pupil of *Corax. *Plato(1) (Phdr. 267a ff.) is the earliest evidence for Tisias' having taught the importance of probability (εἰκός) and the power of speech to revalue things. As with Corax, there are reasonable doubts about the form and content of his teaching.
