Men are able to assist fortune but not to thwart her. They can weave her designs, but they cannot destroy them.

Real generosity toward the future lies in giving all to the present.

The world is dying of machinery; that is the great disease, that is the plague that will sweep away and destroy civilization; man will have to rise against it sooner or later.

He alone who owns the youth gains the future.

People will not look forward to posterity who never look backward to their ancestors.
