There is a book by a neuroscientist named Raymond Tallis titled In Defense of Wonder. In it he discusses things like memory, time, and so on. He goes through some interesting topics and turns them over in a way that leaves the reader to, well, wonder. I haven't yet read it through, but I've seen snippets of it and it seems it would be a good antidote to the type of philosophical thinking that often leads to cynicism.

I've read some of his other works and enjoyed them. Hopefully I'll get around to reading this one soon. Maybe it'll help reinvigorate some of that childlike wonder I seem to have lost as I've gotten older.
