lungs, "That the most certain way is to agree with what they tell him; to allow himself to be guided by them;" in short, they persuade him to shut his eyes, that he may with greater perspicuity distinguish the road he is to travel: once arrived at this influence, they indelibly fix their lessons; irrevocably chain him to the oar; by holding up to his view the punishments intended for him by these imaginary beings, in case he refuses to accredit, in the most liberal manner, their marvellous inventions; this argument, although it only supposes the thing in question, serves to close his mouth--to put an end to his research; alarmed, confused, bewildered, he seems convinced by this victorious reasoning--attaches to it a sacredness that fills him with awe--blindly conceives that they have much clearer ideas of the subject than himself--fears to perceive the palpable contradictions of the doctrines announced to him, until, perhaps, some being, more subtle than those who have enslaved him, by labouring the point incessantly, attacking him on the weak side of his interest, arrives at throwing the absurdity of his system into light, and finally succeeds by inducing him to adopt that of another set of speculators. The uninformed man generally believes his priests have more senses than himself; he takes them for superior beings; for divine men. He only sees that which these priests inform him he must contemplate; to every thing else his eyes are completely hoodwinked; thus the authority of the priests frequently decides, without appeal, that which is useful perhaps only to the priesthood. When we shall be disposed to recur to the origin of things, we shall ever find that it has been man's imagination, guided by his ignorance, under the influence of fear, which gave birth to his gods; that enthusiasm or imposture have generally either embellished or disfigured them; that credulity readily adopted the fabulous accounts which interested duplicity promulgated respecting them; that these dispositions, sanctioned by time, became habitual. Tyrants finding their advantage in sustaining them, have usually established their power upon the blindness of mankind, and the superstitious fears with which it is always accompanied. Thus, under whatever point of view it is considered, it will always be found that _error cannot be useful to the human species._
