 That virtue is a form of continence for Kant is also suggested by his treatment of other traits such as gratitude and sympathy. Although Kant thinks that feelings cannot be required of anyone, some feelings are nevertheless associated with the moral ends we adopt. If we adopt others’ happiness as an end, we will not take malicious pleasure in their downfall. On the contrary, we will naturally feel gratitude for their benevolence and sympathy for their happiness. These feelings will make it easier for us to perform our duties and are a sign that we are disposed to do so. Kant remarks of sympathy that “it is one of the impulses that nature has implanted in us to do what the representation of duty alone would not accomplish” (Kant, Metaphysics of Morals, Ak. 457).
