Man has been endowed with reason, with the power to create, so that he can add to what he's been given. But up to now, he hasn't been a creator, only a destroyer. Forests keep disappearing, rivers dry up, wild life's become extinct, the climate's ruined, and the land grows poorer and uglier every day.
What is the imagination? Only an arm or weapon of the interior energy; only the precursor of the reason.
Reason is, and ought only to be the slave of the passions.
The heart has its reasons which reason knows nothing of.
A singer can shatter glass with the proper high note,he said,but the simplest way to break glass is simply to drop it on the floor.
To save the world requires faith and courage: faith in reason, and courage to proclaim what reason shows to be true.
The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.
