A person’s merits are his or her admirable qualities. Moral merits usually include such virtues as benevolence, temperance, justice, mercy, etc. Non-moral merits may include cheerfulness, intelligence, strength, musicality, etc. The basis of the distinction is that moral failing involves a defect of the will so that lack of moral merit is thought to be a fault, whereas lack of non-moral merit merely argues bad luck. In Kant, moral merit shrinks to respect for the duty of governing conduct by the categorical imperative, with everything else a mere handmaiden to this end. At the other end of the scale, in Greek thought, and in Hume, the voluntary/involuntary distinction cannot bear the weight, so there is no serious distinction between moral and non-moral merit.
