Harmful Beliefs of some Religions:

A plunge in the dark is a dangerous proceeding, but it is infinitely more dangerous to believe in things that not only have no bearing on our present life but sometimes are actually harmful in their effects on the building of our character. By way of illustration I may refer to doctrines like the Atonement, Predestination, Fatalism and the Transmigration of the Soul. No one can prove any of these by reference to anything in this present life. They may seem plausible to some, but belief in them mainly concerns things as to which we are utterly in the dark. On the other hand, they produce no wholesome effects on this life, nor do they leave any incentive for action. In fact, when taken literally they prompt no action at all.
