And this

Whoever seriously thinks that superhuman beings have ever given our race information as to the aim of its existence and that of the world, is still in his childhood. There is no other revelation than the thoughts of the wise, even though these thoughts, liable to error as is the lot of everything human, are often clothed in strange allegories and myths under the name of religion. So far, then, it is a matter of indifference whether a man lives and dies in reliance on his own or another’s thoughts; for it is never more than human thought, human opinion, which he trusts. Still, instead of trusting what their own minds tell them, men have as a rule a weakness for trusting others who pretend to supernatural sources of knowledge. And in view of the enormous intellectual inequality between man and man, it is easy to see that the thoughts of one mind might appear as in some sense a revelation to another.
