Philosopher and author John Gray talks about his book, Seven Types of Atheism. Rather than being about atheism, this is really a rejoinder to the rational optimism of Matt Ridley and Steven Pinker. While conceding that technological know-how and scientific knowledge improve over time, Gray argues that morality and political systems are cyclical and that there is no reason to be optimistic about the future.
