By waging war against Reason, which they ought to have protected and developed, the ministers of the gods evidently act against their own interest. What power, influence, and respect might they not have gained among the wisest of men, what gratitude would they not have excited in the people, if, instead of wasting their time about their vain disputes, they had applied themselves to really useful science, and investigated the true principles of philosophy, government, and morals! Who would dare to reproach a body with its opulence or influence, if the members dedicating themselves to the public good, employed their leisure in study, and exercised their authority in enlightening the minds both of sovereigns and subjects?
Priests! Forsake your chimeras, your unintelligible dogmas, your contemptible quarrels! Banish those phantoms which could be useful only in the infancy of nations. Assume, at length, the language of reason. Instead of exciting persecution; instead of entertaining the people with silly disputes; instead of preaching useless and fanatical dogmas, preach human and social morality; preach virtues really useful to the world; become the apostles of reason, the defenders of liberty, and the reformers of abuses.

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.

The partisans of credulity often accuse unbelievers of insincerity, because they sometimes waver in their principles, alter their minds in sickness, and retract at death. When the body is disordered, the faculty of reasoning is commonly disordered with it. At the approach of death, man, weak and decayed, is sometimes himself sensible that Reason abandons him, and that Prejudice returns. There are some diseases, which tend to weaken the brain; to create despondency and pusillanimity; and there are others, which destroy the body, but do not disturb the reason. At any rate, an unbeliever who recants in sickness is not more extraordinary, than a devotee who neglects in health the duties which his religion explicitly enjoins.
