The Story of the Raven & The Crow

Corax (the Raven) and Tisias (the Crow) are considered to be the originators of Rhetoric, which is the foundation of Persuasion & Public Speaking.

Corax, a Master Speaker in Ancient Greece, takes on a young student, Tisias, who is eager to make his fortune as a lawyer. Tisias contracted to pay Corax only after he wins a lawsuit. However, after completing his training Tisias becomes complacent and does not bring a case to court for years. Tired of waiting to be paid, Corax decides to take Tisias to court.

If I should lose my case, it will surely prove that I was not taught rhetoric very well. And this being the case I should NOT have to pay the tuition. For no one should have to pay for services that weren’t rendered according to what was promised. On the other hand, if I win the case, it shows that I had enough sense and talent to figure out the art of rhetoric out on my own, despite the negligence of my instructor. But even this is not necessary to my case. For a ruling against Corax, is a ruling for me. And a ruling for me means I do not have to pay tuition. In either case, then, I should NOT have to pay tuition.
— Tisias
If you rule against me — that is if Tisias does in fact win his case — it serves to show that I taught him rhetoric well, in which case he should be required to pay my tuition. If, however, Tisias does not win his case, that would show him to be a poor, or rather bad, student. Those who are wise will know that a teacher is not to be faulted if, in discharging his services well and faithfully, the student is simply too stupid or too lazy to take advantage of those services, expertly rendered. A ruling against Tisias is a ruling in favor of me. Such a ruling would mean that Tisias must pay my tuition. In either case, then, my tuition should be paid.
— Corax

Who do you think wins this case?

The one who DELIVERS their argument the best!!
