An entertaining but intellectually lightweight run-through of numerous philosophical questions. Many brief biographies, followed by a half page summary of a key part of their work, which is usually dismissed with a few pages summarizing some results from the empirical research, mostly psychology.
An idea he very briefly mentions which I found very interesting and relevant today is that of 'attention theft', I suspect that there could be a good case for it, with the result that there ought to be legal protections for individuals' attention.
