When we think of any virtuous or great deed, we can not help thinking of the pain and obstacles that have to be met with in performing that deed.

All our active morality is a struggle against immorality.

And I think that, as every religion teaches, it must be granted that no human being has a perfectly moral nature.
Could a world exist in which the nature of all the inhabitants would be so moral that the mere idea of what is immoral could not exist?
Let me explain my question more in detail.

Imagine a society in which the idea of dishonesty would not exist, because no person could be dishonest, a society in which the idea of unchastity could not exist, because no person could possibly be unchaste, a world in which no one could have any idea of envy, ambition or anger, because such passions could not exist, a world in which there would be no idea of duty, filial or parental, because not to be filial, not to be loving, not to do everything which we human beings now call duty, would be impossible.

In such a world ideas of duty would be quite useless; for every action of existence would represent the constant and faultless performance of what we term duty.
