Well, to some extent we're arguing semantics and perhaps common usage would
associate "purpose" only with conscious entities like animals. But although
I don't ascribe consciousness to Gaea or to evolution (though I wouldn't rule
it out) certainly I thing any problem solving system can fairly be described
as "goal seeking" and when such systems are highly complex they are more
usefully analysed in those terms. To attempt to analys evolutionary process
in purely mechanistic terms seems to me rather like trying to understand
creative writing in terms of neurophysics.
