Would you take a lizard
it, and then stomp
until it's flat, and then keep stomping until it's been broken up into
and look at that and then say, "Aha! Now I
understand a lizard."?
The short answer is, "Of course not."
The long answer is much more interesting, and begins with, "Well, no,
but I should understand that a lizard has water and carbon in it, and
I had better also understand water and carbon on their own. Then I
might have a shot at understanding a lizard."
I find this comes up surprisingly often in conversations at 3am.
