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?

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

Religion has ever filled the mind of man with darkness, and kept him in ignorance of his real duties and true interests. It is by dispelling the clouds and phantoms of religion, that we shall discover truth, morality and reason. Religion diverts us from the causes of evils, and from these remedies which nature advocates, far from curing; it only aggravates, perpetuates and multiplies them.

When we examine the opinions of men, we find that nothing is more uncommon, than common sense; or, in other words, they lack judgment to discover plain truths, or to reject absurdities, and palpable contradictions.

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.

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.

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.
