Reviewing something like Carl Sagan’s Cosmos is a tricky proposition. On the one hand, it’s a book by an acclaimed scientist – and more significantly one of the eminent science writers and presenters of the 20th Century. It’s also a companion volume to one of what is considered to be one of the best science television series of all time. Hard stop. On the other hand, it’s hard for me to say that any particular author or work is above criticism or discussion – and I’ll admit we don’t talk about the book the way we talk about the TV show – so I’m going to give it a shot anyway.
