The intellectual advancement of man depends on how often he can exchange an old superstition for a new truth

A great man is a torch in the darkness, a beacon in superstition's night, an inspiration and a prophecy.

Science built the Academy, superstition the inquisition

There are some truths, however, that we should never forget: Superstition has always been the relentless enemy of science; faith has been a hater of demonstration; hypocrisy has been sincere only in its dread of truth, and all religions are inconsis

A great man does not seek applause or place; he seeks for truth; he seeks the road to happiness, and what he ascertains, he gives to others.
