In the Critique of Practical Reason, Kant presents virtue not as an arduous task, but as an endeavor, that costs a lot for the agent. In order to explain in what consists moral content, Kant tells a story of an honest man, to whom it is offered great gifts if he joins the calumniators of an innocent person, but he denies it. Then he is threatened by his friends, who deny him friendship, by his relatives, who deny him inheritance, and a prince who threatens him with loss of freedom and even life. If the man, whatever loss or pain he is threaten with, decides to be truthful, then he shows here the value of virtue. Moreover “yet virtue here worth so much because it costs so much, not because it brings any profit” (KpV, 5:156)1. Virtue shows its worth, even to the youngest listener, because of his pureness and deserves approval and admiration, because moral actions were done without any pretension to happiness or even magnanimity. In this article, I analyze the idea of virtue in Kant and how it is related to the controlling of affects and passions. I begin by showing the relation between virtue and happiness and then I explore virtue as strength.
