Attitude 1 is a true description of what is going on; but if you're dealing with a large, complex system that you can never grok completely, then Attitude 2 seems to be a more useful way of approaching things. At least sometimes. Attitude 1 seems like particle physics, which isn't much use for describing macroscopic processes like a bouncing tennis ball.
