Something about naive liberal humanitarianism often bugs and irritates me more than correspondingly naive reactionary beliefs, and I (probably wrongly) end up judging more severely than I should otherwise good people who espouse it naively.
When I say that the probability of throwing 3 heads in succession is 1/8, that refers to the fact that if I toss three coins a large number of times, I believe that the number of times I get three simultaneous heads will asymptotically approach a ratio of 1/8. Each individual throw is of course governed by well understood mechanical laws, but the sequence of uncontrolled tiny effects at the start of and during each coin toss effectively produces a pseudo-random result.
In quantum mechanics — i.e. in the real world as we understand it today — matter can have two kinds of formerly apparently contradictory qualities.
