An answer to A Frequent question: What are you reading?

Some time ago, in response to a frequent question "What are you reading?", I decided to simply keep a running list. So, in my continuous self-study, I put on top the book I'm currently reading and allow the oldest one to drop away, thereby keeping the list to not more than 20. The list below covers a period of about 18 months. Because I am so curious about so many things and I love to consider the intersection of ideas, this diverse and ever-changing list provides me many insights, including a meta-view of current influences.
