The inward persuasion that we are free to do, or not to do a thing, is but a mere illusion. If we trace the true principle of our actions, we shall find, that they are always necessary consequences of our volitions and desires, which are never in our power. You think yourself free, because you do what you will; but are you free to will, or not to will; to desire, or not to desire? Are not your volitions and desires necessarily excited by objects or qualities totally independent of you?

If experience be consulted, it will be found there is no action, however abominable, that has not received the applause of some people. Parricide - the sacrifice of children - robbery - usurpation - cruelty - intolerance - prostitution, have all in their turn been licensed actions, and have been deemed laudable and meritorious deeds with some nations of the earth. Above all, Religion has consecrated the most unreasonable, the most revolting customs.

If the ministers of the Church have often permitted nations to revolt for Heaven's cause, they never allowed them to revolt against real evils or known violencess. It is from Heaven that the chains have come to fetter the minds of mortals.

Nature, you say, is totally inexplicable without a God. That is to say, to explain what you understand very little, you have need of a cause which you understand not at all.

The source of man's unhappiness is his ignorance of Nature.

These principles, universally recognized, are at fault when the question of the existence of God is considered; what has been said of Him is either unintelligible or perfectly contradictory; and for this reason must appear impossible to every man.

Many men without morals have attacked religion because it was contrary to their inclinations. Many wise men have despised it because it seemed to them ridiculous. Many persons have regarded it with indifference, because they have never felt its true disadvantages. But it is as a citizen that I attack it, because it seems to me harmful to the happiness of the state, hostile to the march of the mind of man, and contrary to sound morality, from which the interests of state policy can never be separated.
