Socrates was killed by being forced to drink the juice of the poisonous herb called hemlock.
Just before he drank the poison, one of his disciples asked him, “Master, are you not afraid of dying? You appear to be so calm”.
Socrates replied, “Why should I be ? I know that only two things can happen after death. Either I will continue to exist, in some other form or name, or I will cease to exist after death. In the first case, there is nothing to worry about. In the second case, who will remain to worry? So either way, there is nothing to fear!”.
