There is, indeed, a most dangerous passage in the history of a democratic people. When the taste for physical gratifications among them has grown more rapidly than their education and their experience of free institutions, the time will come when men are carried away and lose all self-restraint at the sight of new possessions they are about to obtain. In their intense and exclusive anxiety to make a fortune they lose sight of the close connection that exists between the private fortune of each and the prosperity of all.

Muhammad professed to derive from Heaven, and he has inserted in the Koran, not only a body of religious doctrines, but political maxims, civil and criminal laws, and theories of science. The gospel, on the contrary, only speaks of the general relations of men to God and to each other - beyond which it inculcates and imposes no point of faith.
