"Metaphysics of morals is therefore indispensable necessary, not merely because of a motive to speculation -- for investigating the source of the practical basic principles' that lie a priori in our reason -- but also because morals themselves remain subject to all sorts of corruption as long as we are without that clue and supreme norm by which to appraise them correctly" (Kant p.3).

Doing an action simply because one knows it is the right thing to do, and may bring a smile to the face of someone else.
