“It is a proud and lonely thing to be a stainless steel rat - and it is the greatest experience in the galaxy if you can get away with it. The sociological experts can't seem to agree why we exist, some even doubt that we do. The most widely accepted theory says that we are victims of delayed psychological disturbance that shows no evidence in childhood when it can be detected and corrected and only appears later in life. I have naturally given a lot of thought to the topic and I don't hold with that idea at all. [...]
My theory is that the aberration is a philosophical one, not a psychological one. At a certain stage the realization strikes through that one must either live outside of society's bonds or die of absolute boredom. There is no future or freedom in the circumscribed life and the only other life is complete rejection of the rules. There is no longer room for the soldier of fortune or the gentleman adventurer who can live both within and outside of society. Today it is all or nothing. To save my own sanity I chose the nothing.”
