Why is simplicity assumed to be a rare property? There are large classes of things that tend to be “simple”, like much of mathematics; don’t you have to argue that “brains” or minds belong to the class of things whose members do not tend to be “simple”? (I can see obvious reasons that one would think this is obvious, and non-obvious reasons that one would think this is non-obvious, which makes me think that it shouldn’t be assumed, but if I’m the only person around who could make the non-obvious arguments then I guess we’re out of luck.)
