In expanding the field of knowledge we but increase the horizon of ignorance.

Our knowledge is a receding mirage in an expanding desert of ignorance

Our knowledge is a receding mirage in an expanding desert of ignorance.

The deeper we dig into our field the more we know about its details

Sin, guilt, neurosis /they are one and the same, the fruit of the tree of knowledge.

Only a blind man can easily define what light is. When you do not know, you are bold. Ignorance is always bold; knowledge hesitates. And the more you know, the more you feel that the ground underneath is dissolving. The more you know, the more you feel how ignorant you are.
