Craig Callender is a philosopher of science at UC San Diego, who has written a lot about the nature of time, including a fun illustrated book. He's more than a bit skeptical of the multiverse idea, and somewhat contrarian about the low-entropy nature of the early universe: he thinks it's just a fact we should observe and accept ("nomological"), rather than a feature that cries out for a better explanation. Here we're having a chat on the recently launched Philosophy TV, sort of Bloggingheads for philosophers. Craig's head obviously looms much larger than mine, so I had to use my wiles to bob and weave, intellectually speaking.
