Is man the product of his environment or is temperament the prime determining factor in the choices he makes, or more so, his predisposition toward life in general and the choices that arise out of that predisposition?
Mark Twain talks about this a lot. His short, titled “What Is Man?” addresses it as does “The Turning Point Of My Life.” I think Twain was fascinated by the topic. He also talks of how circumstances stopped some of his activities and provided the impetus for starting of others such as when the civil war ended his career as a riverboat pilot because the boats stopped running and “my livelihood was gone.”
This turn of events was followed by another and Twain hitched a ride on the new career in Nevada and a stint in silver mining.
