Query: Turning point for Watts

I think this book is the earliest example of what would become Watts' philosophy as a whole. I don't really like the title, I think that Watts had something other in mind than what most of us think of when we think of insecurity. The term "insecurity" has come to be associated with a psycholigical condition not unlike depression or anxiety. Given this development, a beter term might be flux, instability, uncertainty, etc. In any event, it is a great book.
