How is it possible, then, Madam, from visionary theories to arrive at these conclusions, and establish from supernatural phantasms the principles of private and public virtue? Shall we launch into unknown regions to ascertain our duty and to keep our station in society? Is it not sufficient if we wish to be happy that we should endeavor to preserve ourselves in those maxims which reason approves, and on which virtue is founded? Every man who would perish, who would render his existence miserable, whoever would sacrifice permanent happiness for present pleasure, is a fool, who reflects not on the interests that are dearest to him. If there are any principles so clear as the morality of humanity has been and is still proved to be, they are such as men ought to observe. They are not obscure notions, mysticism, contradictions, which have made of a science the most obvious and best demonstrated, an unintelligible science, mysterious and uncertain to those for whom it is designed. In the hands of the priests, morality has become an enigma; they have founded our duties on the attributes of a Deity whom the mind of man cannot comprehend, in place of founding them on the character of man himself. They have thrown in among them the foundations of an edifice which is made for this earth. They have desired to regulate our manners agreeably to equivocal oracles which every instant contradict themselves, and which too often render their devotees useless to society and to themselves. They have pretended to render their morality more sacred by inviting us to look for recompenses and punishments removed beyond this life, but which they announce in the name of the Divinity. In fine, they have made man a being who may not even strive at perfection, by a preordination of some to bliss, and consequent damnation of others, whose insensibility is the result of this selection. Need we not, then, wonder that this supernatural morality should be so contrary to the nature and the mind of man? It is in vain that it aims at the annihilation of human nature, which is so much stronger, so much more powerful, than imagination. In despite of all the subtile and marvellous speculations of the priests, man continues always to love himself, to desire his well being, and to flee misfortune and sorrow. He has then always been actuated by the same passions. When these passions have been moderate, and have tended to the public good, they are legitimate, and we approve those actions which are their effects. When these passions have been disordered, hurtful to society, or to the individual, he condemns them; they punish him; he is dissatisfied with his conduct which others cannot approve. Man always loves his pleasures, because in their enjoyment he fulfils the end of his existence; if he exceeds their just bounds he renders himself miserable.
