Join me as I sit down with Alex and David, both previous guests on the show and both cofounders of the Guild of the Rose. Together, we go over the core – the heart – of what we consider to be the Rationalist tradition. The 12 Virtues are an awesome distillation of what the rest of the sequences build on.

Be sure to check out the Guild of the Rose. If our constantly pitching it to you hasn’t been enough to persuade you to check it out, hopefully hearing two more of the founders discuss Rationality in general and giving their own pitches for the Guild will tip the scales.
