The ambitious and the voluptuous have but little time to reason; they have other occupations than that of comparing Lucretius with Socrates. Such is the case with us and our time.

It was otherwise with the Roman senate, which was composed almost entirely of theoretical and practical atheists, that is, believing neither in Providence nor in a future state; this senate was an assembly of philosophers, men of pleasure, and ambitious men, who were all very dangerous, and who ruined the commonwealth. Under the emperors, Epicureanism prevailed. The atheists of the senate had been factious in the times of Sulla and of Cæsar; in those of Augustus and Tiberius, they were atheistical slaves.

I should not wish to come in the way of an atheistical prince, whose interest it should be to have me pounded in a mortar; I am quite sure that I should be so pounded. Were I a sovereign, I would not have to do with atheistical courtiers, whose interest it was to poison me; I should be under the necessity of taking an antidote every day. It is then absolutely necessary for princes and people that the idea of a Supreme Being--creating, governing, rewarding, and punishing--be profoundly engraved on their minds.

There are, nations of atheists, says Bayle in his "Thoughts on Comets." The Kaffirs, the Hottentots, and many other small populations, have no god; they neither affirm nor deny that there is one; they have never heard of Him; tell them that there is one, and they will easily believe it; tell them that all is done by the nature of things, and they will believe you just the same. To pretend that they are atheists would be like saying they are anti-Cartesians. They are neither for Descartes nor against him; they are no more than children; a child is neither atheist nor deist; he is nothing.

From all this, what conclusion is to be drawn? That atheism is a most pernicious monster in those who govern; that it is the same in the men of their cabinet, since it may extend itself from the cabinet to those in office; that, although less to be dreaded than fanaticism, it is almost always fatal to virtue. And especially, let it be added, that there are fewer atheists now than ever--since philosophers have become persuaded that there is no vegetative being without a germ, no germ without a design, etc., and that the corn in our fields does not spring from rottenness.
