Adlai Stevenson II Quote

Unreason and anti-intellectualism abominate thought. Thinking implies disagreement; and disagreement implies nonconformity; and nonconformity implies heresy; and heresy implies disloyalty—so, obviously, thinking must be stopped. But shouting is not a substitute for thinking and reason is not the subversion but the salvation of freedom.

A Call to Greatness (1954), p. 99
