The death of Socrates
Socrates, perhaps the greatest thinker this humble planet has witnessed, said before dying, "Oh, Crito, we owe a rooster to Asclepius, don't forget!" The expression may seem futile, but in Socrates' language, every sound had at least five different interpretations.
Crito was his best friend, and Asclepius was the god of healing. These words were spoken when a court forced him to take poison, a sort of compelled suicide. To this day, no one understands the significance of the rooster, and countless philosophical theses are scattered around, posing many questions with no answers.
Nietzsche, perhaps the greatest thinker this humble planet has witnessed, said before dying, "Mother, I am foolish." This time, reality left no room for interpretations.
