1. Nontrivial emergent complexity
Strict reductionism misses the importance of particular paths through the variance-space. You can tweak the parameters of organism-space or history-space or fractal-space or whatever, but finding an optimal path through them takes nontrivial search time.
2. Aspen, aspirin and empiricism: Finding the seeds of complex value structures in simple impulses
Our basic impulses towards and away from various affectational states only realizable in the context of an environment with a large range of nonobvious solutions to an arbitrarily large problem-set, embedded in various denizens of organism-space.
3. Your intuitions do not occur in a vacuum
Bias is not merely the default human condition; to be raised in a supportive environment has its own warping effects on human psychology.
