What is ignored in this imagery are the intervening areas in which men act and react as social beings.

To find people in our day attempting to pass off to the world and recommending to others some nostrum of the absolute which they claim to have discovered is merely a sign of the loss of and the need for intellectual and moral certainty, felt by broad sections of the population who are unable to look life in the face.
