Those who can make you believe absurdities can make you commit atrocities.
-Voltaire, philosopher (1694-1778)

Voltaire may not have known about the idea that people don't "make" us do anything--we choose our reactions, whether consciously or unconsciously.

But his point still rings true. If you place your belief in someone whose words make "non-sense", you may very well act in ways you would never have otherwise.
