Philosopher Quotes on Virtue
Virtue has been a central category of ethics since the Greeks treated it as the excellence proper to a human being. Plato analyzed the cardinal virtues, Aristotle developed virtue ethics as habituated dispositions of character, and Confucian and Buddhist traditions parallel this concern with cultivated moral excellence. Medieval thinkers added the theological virtues of faith, hope, and charity to the classical inheritance. The modern revival of virtue ethics in the twentieth century returned attention to character and practical wisdom as the ground of moral life.

But most of us carry with us the Jocasta in our hearts, who begs Oedipus, for God's sake, not to inquire further.”
Letter to Johann Wolfgang von Goethe (November 1815) [ citation needed ] -
“The New Testament … must be in some way traceable to an Indian source: its ethical system, its ascetic view of morality, its pessimism, and its Avatar, are all thoroughly Indian.
