There is the inner life, which is the world of final reality, the world of memory, emotion, 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 the inner life and capture answers and evidence to support the answers out of it. 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 do not somehow learn it, then our minds lie in us like the fish in the pond of a man who cannot fish.
