"The short space of sixty years can never shut in the whole of man's imagination; the incomplete joys of this world will never satisfy his heart. Alone among all created beings, man shows a natural disgust for existence and an immense longing to exist; he scorns life and fears annihilation. These different instincts constantly drive his soul toward contemplation of the next world, and it is religion that leads him thither. Religion, therefore, is only one particular form of hope, and it is as natural to the human heart as hope itself. It is by a sort of intellectual aberration, and in a way, by doing moral violence to their own nature, that men detach themselves from religious beliefs; an invincible inclination draws them back. Incredulity is an accident; faith is the only permanent state of mankind."
--Tocqueville, who else?
