Philosophers have every where taken upon themselves a part, which seemed destined to the ministers of Religion. The hatred of the latter for philosophy was only a jealousy of trade. But, instead of endeavouring to injure and decry each other, all men of good sense should unite their efforts to combat error, seek truth, and especially to put to flight the prejudices, that are equally injurious to sovereigns and subjects, and of which the abettors themselves sooner or later become the victims.

In the hands of an enlightened government, the priests would become the most useful of the citizens. Already richly paid by the state, and free from the care of providing for their own subsistence, how could they be better employed than in qualifying themselves for the instruction of others? Would not their minds be better satisfied with discovering luminous truths, than in wandering through the thick darkness of error? Would it be more difficult to discern the clear principles of Morality, than the imaginary principles of a divine and theological Morality? Would men of ordinary capacities find it as difficult to fix in their heads the simple notions of their duties, as to load their memories with mysteries, unintelligible words and obscure definitions, of which they can never form a clear idea? What time and pains are lost in learning and teaching things, which are not of the least real utility! What resources for the encouragement of the sciences, the advancement of knowledge, and the education of youth, well disposed sovereigns might find in the many monasteries, which in several countries live upon the people without in the slightest degree profiting them! But superstition, jealous of its exclusive empire, seems resolved to form only useless beings. To what advantage might we not turn a multitude of cenobites of both sexes, who, in many countries, are amply endowed for doing nothing? Instead of overwhelming them with fasting and austerities; instead of barren contemplations, mechanical prayers, and trifling ceremonies; why should we not excite in them a salutary emulation, which may incline them to seek the means, not of being dead to the world, but of being useful to it? Instead of filling the youthful minds of their pupils with fables, sterile dogmas, and puerilities, why are not priests obliged, or invited to teach them truths, and to render them useful citizens of their country? Under the present system, men are only useful to the clergy who blind them, and to the tyrants who fleece them.
