fact is we respectfully adapt ourselves first, to her ways. "We
attain no power over nature till we learn natural laws, and our
lordship depends on the adroitness with which we learn and conform."

Adroitness however is merely an ability to win; back of it there must
be some spur to make us use our adroitness. Why don't we all die or
give up when we're sick of the world? Because the love of life is
reenforced, in most energized beings, by some longing that pushes
them forward, in defeat and in darkness. All creatures wish to live,
and to perpetuate their species, of course; but those two wishes
alone evidently do not carry any race far. In addition to these, a
race, to be great, needs some hunger, some itch, to spur it up the
hard path we lately have learned to call evolution. The love of toil
in the ants, and of craft in cats, are examples (imaginary or not).
What other such lust could exert great driving force?

With us is it curiosity? endless interest in one's environment?

Many animals have some curiosity, but "some" is not enough; and
in but few is it one of the master passions. By a master passion,
I mean a passion that is really your master: some appetite which
habitually, day in, day out, makes its subjects forget fatigue or
danger, and sacrifice their ease to its gratification. That is the
kind of hold that curiosity has on the monkeys.
