If there were no eternal consciousness in a man, if at the foundation of all there lay only a wildly seething power which writhing with obscure passions produced everything that is great and everything that is insignificant, if a bottomless void never satiated lay hidden beneath all—what then would life be but despair?  —Søren Kierkegaard, Fear and Trembling (1843) 

 

The image is not an idea. It is a radiant node or cluster; it is what I can, and must perforce, call a VORTEX, from which, and through which, and into which ideas are constantly rushing.    —Ezra Pound, "Vorticism" (1914)

 

Thought is gazing on to the face of life, and reading what can be read,
Thought is pondering over experience, and coming to a conclusion.
Thought is not a trick, or an exercise, or a set of dodges,
Thought is a man in his wholeness wholly attending.    —D.H. Lawrence, "Thought"
