_Defence of the Sentiments contained in this Work.--Of Impiety.--Do there exist Atheists?_ What has been said in the course of this work, ought sufficiently to undeceive those who are capable of reasoning on the prejudices to which they attached so much importance. But the most evident truths frequently crouch under fear; are kept at bay by habit; prove abortive against the force of enthusiasm. Nothing is more difficult to remove from its resting place than error, especially when long prescription has given it full possession of the human mind. It is almost unassailable when supported by general consent; when it is propagated by education; when it has acquired inveteracy by custom: it commonly resists every effort to disturb it, when it is either fortified by example, maintained by authority, nourished by the hopes, or cherished by the fears of a people, who have learned to look upon these delusions as the most potent remedies for their sorrows. Such are the united forces which sustain the empire of unintelligible systems over the inhabitants of this world; they appear to give stability to their throne; to render their power immoveable; to make their reign as lasting as the human race. We need not, then, be surprised at seeing the multitude cherish their own blindness; encourage their superstitious notions; exhibit the most sensitive fear of truth. Every where we behold mortals obstinately attached to phantoms from which they expect their happiness; notwithstanding these fallacies are evidently the source of all their sorrows. Deeply smitten with the marvellous, disdaining the simple, despising that which is easy of comprehension, but little instructed in the ways of nature, accustomed to neglect the use of their reason, the uninformed, from age to age, prostrate themselves before those invisible powers which they have been taught to adore. To these they address their most fervent prayers; implore them in their misfortunes, offer them the fruits of their labour; they are unceasingly occupied either with thanking their vain idols for benefits they have not received at their bands, or else in requesting from them favors which they can never obtain. Neither experience nor reflection can undeceive them; they do not perceive these idols, the work of their own hands, have always been deaf to their intreaties; they ascribe it to their own conduct; believe them to be violently irritated: they tremble, groan out the most dismal lamentations; sigh bitterly in their temples; strew their altars with presents; load their priests with their largesses; it never strikes their attention that these beings, whom they imagine so powerful, are themselves submitted to nature; are never propitious to their wishes, but when nature herself is favourable. It is thus that nations are the accomplices of those who deceive them; are themselves as much opposed to truth as those who lead them astray.
