The fundamental evil of government grants is the fact that men are forced to
pay for the support of ideas diametrically opposed to their own. This is a
profound violation of an individual’s integrity and conscience. It is viciously
wrong to take the money of rational men for the support of B.F. Skinner—or
vice versa. The Constitution forbids a governmental establishment of religion,
properly regarding it as a violation of individual rights. Since a man’s
beliefs are protected from the intrusion of force, the same principle should
protect his reasoned convictions and forbid governmental establishments in the
field of thought.
