"There is the inner life of thought which is our world of final reality. The world of memory, emotion, feeling, imagination, intelligence and natural common sense, and which goes on all the time consciously or unconsciously like the heartbeat.
There is also the thinking process by which we break into that inner life and capture answers and evidence to support the answers out of it.
And that process of raid, or persuasion, or ambush, or dogged hunting, or surrender, is the kind of thinking we have to learn, and if we don't somehow learn it, then our minds lie in us like the fish in the pond of a man who can't fish."
- Ted Hughes
