All world-craziness aside, this is the holiday season, so for this episode I thought I would look at hope – and not in some feel-good ‘wishingist’ way. I mean the sort of sensible rigorous and rational stuff that everyone can test for themselves and believe in together, even if they might be skeptical about a whole lot of things – because it really is not only objective but has also proven useful to people across a wide range of experience.
