When a trout rising to a fly gets hooked and finds himself unable to swim about freely, he begins a fight which results in struggles and splashes and sometimes an escape.... In the same way, the human stuggles ... with the hooks that catch him. Sometime he masters his difficulties; sometimes they are too much for him. The struggles are all that the world sees, and it usually misunderstands them. It is hard for a free fish to understand what is happening to a hooked one. Karl A. Menninger (b.1893) "The Human Mind"
My reason for including this in my dissertation:
As an early psychoanalyst, Karl Menninger was probably referring to the criminal mind in this passage. I thought it actually mapped nicely onto the frustrations and joys associated with research and the difficulties that come in trying to explain it to those having no experience with the process. (My brother-in-law is an avid fisherman though!) You may find it of some solace in the future as you attempt to justify your actions regarding the things that "hook" you.
