If a healing technique is demonstrated to have curative properties in properly controlled double-blind trials, it ceases to be alternative. It simply, as Diamond explains, becomes medicine.

It is quite true that many scientists, many physicists, maintain that the physical constants, the half dozen or so numbers that physicists have to simply assume in order to derive the rest of their understanding ... have to be assumed. You can't provide a rationale for why those numbers are there. Physicists have calculated that if any of these numbers was a little bit different, the universe as we know it wouldn't exist.

Though the details differ across the world, no known culture lacks some version of the time-consuming, wealth consuming, hostility provoking rituals, the anti-factual, counter-productive fantasies of religion.

If you don't know anything about computers, just remember that they are machines that do exactly what you tell them but often surprise you in the result.

Whenever I read such a remark, I always feel like writing 'Speak for yourself' in the margin.
