The application of these principles to the given situation in France in 1770 would obviously have produced unwelcome results. Holbach's theory was that religion was worse than useless in that it had inculcated false and pernicious ideas in politics and morals. He would do away completely with it in the interest of putting these sciences on a natural basis. This basis is self-interest, or man's inevitable inclination toward survival and the highest degree of well-being, "L'objet de la morale est de faire connaître aux hommes que leur plus grand intérêt exige qu'ils pratiquent la vertu; le but du gouvernement doit être de la leur faire pratiquer."
Government then assumes the functions of moral restraint formally delegated to religion; and punishments render virtue attractive and vice repugnant. Holbach's theory of social organization is practically that of Aristotle. Men combine in order to increase the store of individual well-being, to live the good life. If those to whom society has delegated sovereignty abuse their power, society has the right to take it from them. Sovereignty is merely an agent for the diffusion of truth and the maintenance of virtue, which are the prerequisites of social and individual well-being. The technique of progress is enlightenment and good laws.
Nothing could be clearer or simpler than Holbach's system. As Diderot so truly said, he will not be quoted on both sides of any question. His uncompromising atheism is the very heart and core of his system and clarifies the whole situation. All supernatural ideas are to be abandoned. Experience and reason are once for all made supreme, and henceforth refuse to share their throne or abdicate in favor of faith. Holbach's aim was as he said to bring man back to nature and render reason dear to him. "Il est tempts que cette raison injustement dégradée quitte un ton pusillamine qui la rendront complice du mensonge et du délire."
If reason is to rule, the usurper, religion, must be ejected; hence atheism was fundamental to his entire system. He did not suppose by any means that it would become a popular faith, because it presupposed too much learning and reflection, but it seemed to him the necessary weapon of a reforming party at that time. He defines an atheist as follows: "C'est un homme, qui détruit des chimères nuisibles au genre humain, pour ramener les hommes à la nature, à l'expérience, à la raison. C'est un penseur qui, ayant médité la matière, ses propriétés et ses façons d'agir, n'a pas besoin, pour expliquer les phénomènes de l'univers et les opérations de la nature, d'imaginer des puissances idéales, des intelligences imaginaires, des êtres de raison; qui loin de faire mieux connaître cette nature, ne font que la rendre capricieuse, inexplicable, et méconnaissable, inutile au bonheur des hommes."
