"In ages of faith, the final aim of life is placed beyond life. The men of such ages are therefore used naturally and, as it were, involuntarily, to fix their gaze for many years on a static object toward which their progress is ever directed, and they learn by imperceptible degrees to repress a thousand small passing desires so as to satisfy more effectively this one great permanent longing which torments them. When these same men wish to concentrate upon worldly affairs, these habits come into their own. They readily settle upon one general and sure goal as an object for their actions here below and direct all their efforts toward it. You do not see them indulging in new projects every day but they do have definite plans which they never tire of pursuing.
This explains why religious nations have often achieved such lasting results. They discovered the secret of success in this world by concentrating upon the next." -- Alexis de Tocqueville
