To be quite accurate, human nature is simply what it is; it has its dark and its light sides. The sum of all colours is grey - light on a dark background or dark on light.

We have forgotten the age-old fact that God speaks chiefly through dreams and visions.

Even the most carefully defined philosophical or mathematical concept, which we are sure does not contain more than we have put into it, is nevertheless more than we assume. It is a psychic event and as such partly unknowable. The very numbers you use in counting are more than you take them to be. They are at the same time mythological elements (for the Pythagoreans, they were even divine); but you are certainly unaware of this when you use numbers for a practical purpose.
