It would therefore be useless to propose more than to hold out reason to those who are competent to understand it; to present truth to those who can sustain its lustre; who can with serenity contemplate its refulgent beauty; to undeceive those who shall not be inclined to oppose obstacles to demonstration; to enlighten those who shall not desire pertinaciously to persist in error. Let us, then, infuse courage into those who want power to break with their illusions; let us cheer up the honest man, who is much more alarmed by his fears than the wicked, who, in despite of his opinions, always follows the rule of his passions: let us console the unfortunate, who groans under a load of prejudices which he has not examined: let us dissipate the incertitude of those whose doubts render them unhappy; who ingenuously seek after truth, but who find in philosophy itself only wavering opinions little calculated to determine their fluctuating minds. Let us banish from the man of genius those chimerical speculations which cause him to waste his time; let us wrest his gloomy superstition from the intimidated mortal, who, duped by his vain fears, becomes useless to society; let us remove from the atrabilarious being those systems that afflict him, that exasperate his mind, that do nothing more than kindle his anger against his incredulous neighbour; let us tear from the fanatic those terrible ideas which arm him with poniards against the happiness of his fellows; let us pluck from tyrants, let us snatch from impostors, those opinions which enable them to terrify, to enslave, and to despoil the human species. In removing from honest men their formidable notions let us not encourage those of the wicked, who are the enemies of society; let us deprive the latter of those illegitimate sources, upon which they reckon to expiate their transgressions; let us substitute actual, present terrors, to those which are distant and uncertain to those which do not arrest the most licentious excesses; let us make the profligate blush at beholding themselves what they really are; let the ministers of superstition tremble at finding their conspiracies discovered; let them dread the arrival of the day, when mortals, cured of those errors with which they have abused them, will no longer be enslaved by their artifice.
