TEST 3: WASTING YOUR TALENT II
Kant says that it is not, since it is not possible to will that the neglect of talent should become a universal law.
He cannot will that we ought to neglect our talents since it is by means of our talents that we develop and improve our lives, and this is what a rational being aims for.
That is, a rational being will necessarily will that his abilities be developed since they are useful to him, and serve any number of purposes. Accordingly, he cannot at the same time will that they be neglected without contradicting himself.
