ANTEATER: Ant colonies have been subjected to the rigors of evolution for billions of years. A few mechanisms were selected for, and most were selected against. The end result was a set of mechanisms which make ant colonies work as we have been describing. If you could watch the whole process in a movie-running a billion or so times faster than life, of course-the emergence of various mechanisms would be seen as natural responses to external pressures, just as bubbles in boiling water are natural responses to an external heat source. I don't suppose you see 'meaning' and 'purpose' in the bubbles in boiling water-or do you? Prelude . . . Ant Fugue 174 CRAB: No, but -- ANTEATER: Now that's my point. No matter how big a bubble is, it owes its existence to processes on the molecular level, and you can forget about any 'higher-level laws.' The same goes for ant colonies and their teams. By looking at things from the vast perspective of evolution, you can drain the whole colony of meaning and purpose. They become superfluous notions.
