Is [God] willing to prevent evil but not able? Then is he impotent. Is he able but not willing? Then is he malevolent. Is he both able and willing? Whence then is evil?
Human decency is not derived from religion. It precedes it.
Philosophy begins where religion ends, just as by analogy chemistry begins where alchemy runs out, and astronomy takes the place of astrology.
Sigmund Freud was quite correct to describe the religious impulse, in The Future of an Illusion, as essentially ineradicable until or unless the human species can conquer its fear of death and its tendency to wish-thinking.
A further difficulty is the apparent tendency of the Almighty to reveal himself only to unlettered and quasi-historical individuals, in regions of Middle Eastern wasteland that were long the home of idol worship and superstition, and in many instances already littered with existing prophecies.
But the human wish to credit good things as miraculous and to charge bad things to another account is apparently universal.
We do not believe in heaven or hell, yet no statistic will ever find that without these blandishments and threats we commit more crimes of greed or violence than the faithful.
There still remain four irreducible objections to religious faith: that it wholly misrepresents the origins of man and the cosmos, that because of this original error it manages to combine the maximum of servility with the maximum of solipsism, that it is both the result and the cause of dangerous sexual repression, and that it is ultimately grounded on wish-thinking.
In the end all good is rewarded and all evil punished, if not actually in this form of life then in the later existences that begin after death. In this way all the terrors, the sufferings and the hardships of life are destined to be obliterated.
