The man who improves himself, improves the world.

He adds one more true man to the mass.

And the mass being made up of individuals, it is clear that were each to improve himself, the result would be the improvement of the whole.

Social advancement is the consequence of individual advancement.
The whole cannot be pure, unless the individuals composing it are pure.
Society at large is but the reflex of individual conditions.

All this is but the repetition of a truism, but truisms have often to be repeated to make their full impression.
Then again, a man, when he has improved himself, is better able to improve those who are brought into contact with him.
