church has been brought to bear against philosophers and scientists in
order to compel a denial of the authority of demonstration,--and to
induce some Judas to betray Reason, one of the saviors of mankind.

During that frightful period known as the "Dark Ages," Faith reigned,
with scarcely rebellious subject. Her temples were "carpeted with
knees," and the wealth of nations adorned her countless shrines. The
great painters prostituted their genius to immortalize her vagaries,
while the poets enshrined them in song. At her bidding, man covered the
earth with blood. The scales of justice were turned with gold, and for
her use were invented all the cunning instruments of pain. She built
cathedrals for God, and dungeons for men. She peopled the clouds with
angels and the earth with slaves. For centuries the world was retracing

a few heretics cried, "Halt!" to the great rabble of ignorant devotion,
and made it possible for the genius of the nineteenth century to
revolutionize the cruel creeds and superstitions of mankind.

The thoughts of man, in order to be of any real worth, must be free.
Under the influence of fear the brain is paralyzed, and instead of
bravely solving a problem for itself, tremblingly adopts the solution of

simply impossible. As fast as phenomena are satisfactorily explained
