An Insight into the Human Psyche

I am currently reading a book (An Absence of Light) by Texan David Lindsey. Built into a character assessment of the main character is this assessment of that characters opinion of the human psyche. Wow! what a mouthful, but on with a direct reprint of his words that summaries my thoughts.

Marcus Graver had made a career of collecting other people's secrets. He had learned early on that most men were so complex a mixture of what was traditionally considered good and bad that to assign either value to any one individual was to commit a gross over-simplification. His personal philosophy about human nature had ranged all the way to the farthest margins of cynicism and back again, and now his own views were so bedeviled by disappointments and buoyed to hope by those rare, but inevitable acts of selflessness, that he no longer had a coherent philosophy at all. No one theory or doctrine seemed to him to contain a suitable explanation for the astounding diversity of behavior of which a single individual was capable.

Thank you Mr Lindsay, just change all the references to 'he' and 'his' to 'me, my or I'.
