The perfect human being is all human beings put together, it is a collective, it is all of us together that make perfection.
I know you won't believe me, but the highest form of Human Excellence is to question oneself and others.
To fear death is nothing other than to think oneself wise when one is not. For it is to think one knows what one does not know. No one knows whether death may not even turn out to be the greatest blessings of human beings. And yet people fear it as if they knew for certain it is the greatest evil.
Remember, no human condition is ever permanent. Then you will not be overjoyed in good fortune nor too scornful in misfortune.
