The first example, that "a man who has been brought by a series of troubles to the point of despair," is meant to illustrate: a duty to ourselves an imperfect duty the universal imperative of a duty

Hello there!

This example is meant to illustrate an imperfect duty.

Explanation:

Immanuel Kant developed what we know as the Kantian theory. This was developed a product of enlightment-rationalism. In this theory, he distinguished perfect and imperfect duties. So, the imperfect duties -according to Kant- can be flexible and be applied at a certain period of time and in particular spaces.

And as the example says, not all the men despairs after a series of troubles. It is flexible and that is why it is an imperfect duty.
