The ancient lights Among the countless legacies we have inherited from Greek and Roman civilizations, I would like to speak here about rationality. What is rationality? It is the primacy of reason in human interactions, that is, the necessity of discussing everything, of debating with one goal in mind: not to determine who is right, but to assess the soundness of our arguments, based on logical truths and factual truths.

We can think of Ajax who, disappointed at having been deprived of Achilles' weapons in favor of Ulysses, descends into furious madness and massacres a flock of sheep, believing them to be the leaders of the Greek army, before committing suicide when he regains his senses.
