These considerations prove how dangerous are the priesthood, since the end they purpose by all their projects is dominion over the mind of mankind, and by subjugating it to enslave their persons, and render them the creatures of despotism and tyranny. And we shall find, upon examination, that, with one or two exceptions, the pious have been the enemies of the progress of science and the development of the human understanding; for by brutalizing mankind they have invariably striven to bind them to their yoke. Their avarice, their thirst of power and wealth, have led them to plunge their fellow-citizens in ignorance, in misery, and unhappiness. They discourage the cultivation of the earth by their system of tithes, their extortions, and their secret projects; they annihilate activity, talents, and industry; their pride is to reign on the ruin of the rest of their species. The finest countries in Europe have, when blindly submissive to the priest, been the worst cultivated, the thinnest peopled, and the most wretched. The _Inquisition_ in Spain, Italy, and Portugal has only tended to impoverish those countries, to debase the mind, and render their subjects the veriest slaves of superstition. And in countries where we see heaven showering down abundance, the people are poor and famished, while the priests and monks are opulent and bloated. Their kings are without power and without glory; their subjects languish in indigence and wretchedness. The priests boast of the utility of their office. Independently of their prayers, from which the world has for so many ages derived neither instruction nor peace, prosperity nor happiness, their pretensions to teach the rising generations are often frivolous, and sometimes arrogant, since we have found others equally well calculated to the discharge of those functions, who have been good citizens, that have not drawn from the pockets of their neighbors the tenth of their earnings. Thus, in what light soever we view them, the pretensions of the priests are reduced to a nonentity, compared to the disservice they render the community by their exactions and dissolute lives.
