Brooke's Reviews > The Varieties of Scientific Experience: A Personal View of the Search for God

This book is a collection of the lectures Sagan gave during his Gifford Lectures appointment in Glasglow. Although he gave the lectures in 1985, they needed very little updating (done with minimal footnotes) upon their publication in 2006. I think the only thing I noticed that is irrelevant now is Sagan's musings about whether or not the universe is forever expanding, and the implications of a universe that expands and contracts (a footnote helpfully reveals that evidence now shows a rapidly expanding universe).

I've noticed many reviews on Goodreads refer to Sagan as an atheist, which isn't correct (he's been quoted elsewhere that an atheist would have to know a lot more than Sagan does), but I can see how it's easy to come away from the book with that idea - his agnostic stance isn't really demonstrated until the Q&A transcript at the end of the lectures, where he points out that you can't prove something without evidence, but that a lack of evidence is not proof that something doesn't exist.

There's a little bit of an overlap between this and Sagan's The Demon-Haunted World Science as a Candle in the Dark, but I think this is the better book; as I noted in my review of The Demon-Haunted World, the latter part of that book seems like a tangent that doesn't quite fit with the first part. The lectures in this collection, on the other hand, all go together very well and transition into each other nicely. On the other hand, The Demon-Haunted World demonstrates more of the balance between Sagan's wonder and skepticism. The lectures come off as being more on the skeptic side.
