Just supposing for the sake of the argument that there is a being of such a kind as that He may with any propriety be called "God", it does seem antecedently very improbable that weak and limited creatures of a day, such as we are, should discover Him by our own efforts.... who could be discovered in that way would hardly be worth discovering. I think we ought to stick to that principle rather firmly. I think we ought to be rather sure that we cannot know God unless God has been pleased to reveal Himself to us.
