"There is a science that has for its object only things incomprehensible. Contrary to all other sciences, it treats only of what cannot fall under our senses, Hobbes calls it the kingdom of darkness. It is a country, where every thing is governed by laws, contrary to those which mankind are permitted to know in the world they inhabit. In this marvelous region, light is only darkness; evidence is doubtful or false; impossibilities are credible: reason is a deceitful guide; and good sense becomes madness. This science is called Theology, and this theology is a continual insult to this reason of man."

“Suns are extinguished or become corrupted, planets perish and scatter across the wastes of the sky; other suns are kindled, new planets formed to make their revolutions or describe new orbits, and man, an infinitely minute part of a globe which itself is only an imperceptible point in the immense whole, believes that the universe is made for himself.”

“Men are naturally disposed to listen to, and believe those who make them hope for an end to their miseries. Misfortunes render them timorous and credulous, and lead them to superstition. A fanatic easily makes conquests among a wretched people. It is not then wonderful that Jesus should soon acquire partizans, especially among the populace who in every country are easily seduced.”

“Savage and furious nations, perpetually at war, adore, under diverse names, some God, conformable to their ideas, that is to say, cruel, carnivorous, selfish, blood-thirsty.”

“Jesus, whose birth was very equivocal, had particular reasons for wishing that adultery should be treated with indulgence. Independently of Mary his mother, from whom Joseph was probably separated, our preacher had in his train dames, whose conduct had not been irreproachable anterior to their conversion. Besides Mary Magdalene, who was a noted courtesan, Jesus had in his suite Joanna, wife of Chuza, Herod's steward, who, according to the tradition, robbed and forsook her husband to follow the messiah, and assist him with her property. Moreover, the indulgence which he preached must have gained him the hearts of all the ladies in his auditory.”

“We are all just cogs in a machine, doing what we were always meant to do, with no actual volition.”

“The universe can be only what it is; all sensible being there enjoy and suffer, that is, are moved sometimes in an agreeable, and sometimes in a disagreeable manner. these effects are necessary; they result necessarily from causes, which act only according to their properties.”
