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.

In line with my reflection on kairos, which concluded on the necessary effort with which to strive towards introspective and in-depth knowledge of oneself, it is now logical that we take on board this maxim as famous as it is misunderstood: "know thyself", Γνῶθι σεαυτόν.

Nothing is given, everything is to be conquered, and the aspiration to the sublime is what we are allowed to experience in Florence: time has stopped there on good taste, on beauty "universal and without concept", as Emmanuel Kant would later say.
