Rudolf Otto,
Naturalism and Religion
“ It is indeed a fact that what alone we can fitly speak of and love as religion—the sense of mystery and the gentle shuddering of piety before the depth of phenomena and their everlasting divine abysses,—has its true place and kingdom in the world of mind and history, with its experiences, riddles, and depths. But mystery is to be found in the world of nature as well. It is only to a very superficial study that it could appear as though nature were, or ever could become, plain and obvious, as if the veil of Isis which shrouds its depths from all investigation could ever be torn away. ”
