In consequence of these ideas, which have their growth in an unhappy temperament, which originate in a peevish humour, which are the offspring of a disturbed imagination, the superstitious are constantly infected with terror, are the slaves to mistrust, the creatures of discontent, continually in a state of fearful alarm. Nature cannot have charms for them; her countless beauties pass by unheeded; they do not participate in her cheerful scenes; they look upon this world, so marvellous to the happy man, so good to the contented enthusiast, as a _valley of tears_, in which a vindictive fate has placed them only to expiate crimes committed either by themselves or by their fathers; they consider themselves as sent here for no other purpose than to be the sharers of calamity; the sport of a capricious fortune; that they are the children of sorrow, destined to undergo the severest trials, to the end that they may everlastingly arrive at a new existence, in which they shall be either happy or miserable, according to their conduct towards the ministers of a being who holds their destiny in his hands. These dismal notions have been the source of all the irrational systems that have ever prevailed; they have given birth to the most revolting practices, currency to the most absurd customs. History abounds with details of the most atrocious cruelties, under the imposing name of public worship; nothing has been considered either too fantastical or too flagitious by the votaries of superstition. Parents have immolated their children; lovers have sacrificed the objects of their affection; friends have destroyed each other: the most bloody disputes have been fomented; the most interminable animosities have been engendered, to gratify the whim of implacable priests, who by crafty inventions have obtained an influence over the people; to please blind zealots, who have never been able either to give fixity to their ideas, or to define their own feelings. Idle dreamers nourished with bile, intoxicated with theologic fury--atrabilarians, whose melancholic humour frequently disposes them to wickedness--visionaries, whose devious imaginations, heated with intemperate zeal, generally leads them to the extremes of fanaticism, working upon ignorance, whose usual bias is credulity, have incessantly disturbed the harmony of mankind, kindled the inextinguishable flame of discord, and in an almost uninterrupted succession, strewed the earth with the mangled carcasses of the multitudinous victims to mad-brained error, whose only crime has been their incapacity to dream according to the rules prescribed by these infuriate maniacs; although these have never been uniform--never assimilated in any two countries--never borne the same features in any two ages, nor even had the united concurrence of the persecuting contemporaries.
