This book contains 38 separate articles which are about culture. By culture I mean everything about human behaviour which is arbitrary. Language is one aspect of culture and there is a set of articles about this and its curiosities. The second set are generally speculative and often indicate some potential for useful change.
Experience, especially in places other than your home town, can trigger many types of responses, and almost certainly some learning. I was optimistic enough to go and live and work in a wide variety of places in different continents. From such places your perspective is automatically reorientated. These collected articles are one result.
