And of course one must not forget cognition, a later stage still. For even life is somewhat empty and uninteresting in the absence of all cognition.

By the way, before it gets too widely accepted that particles and waves are in contrast somehow, I would point out that a view popularized by Lande (and which I think is spot on) is that the particle and wave pictures function hand in hand. This is the truer meaning of complementary-- neither has its full meaning without the other. Wave mechanics tell particles where to go, particle attributes are what give the wave mathematics physical meaning. Neither means much without the other, once the problematic concept of "trajectory" is dispensed with.
