I've been in podcast heaven this week. Krista Tippet's Speaking of Faith podcast is a treasure. She recently spoke with author, poet, and doubter, Jennifer Michael Hecht about the history of doubt. I appreciate Jennifer's ability to rescue the tradition of skepticism from the anger of today's new atheists. Lately, I've come to see faith and doubt as complimentary ingredients in our cocktail of thought. When was the last time you enjoyed a glass of lemon juice or a spoon full of sugar? We may disagree about the perfect recipe for lemonade and some of us may opt for more experimentation over more traditional mixtures, but most of us will agree that the bitter-sweet sum of these ingredients is much better than its parts.
