DEVIL. None, my friend. You think, because you have a purpose,
Nature must have one. You might as well expect it to have fingers and
toes because you have them.

DON JUAN. But I should not have them if they served no purpose. And I,
my friend, am as much a part of Nature as my own finger is a part of me.
If my finger is the organ by which I grasp the sword and the mandoline,
my brain is the organ by which Nature strives to understand itself.
My dog's brain serves only my dog's purposes; but my brain labors at a
knowledge which does nothing for me personally but make my body bitter
to me and my decay and death a calamity. Were I not possessed with a
purpose beyond my own I had better be a ploughman than a philosopher;
for the ploughman lives as long as the philosopher, eats more, sleeps
better, and rejoices in the wife of his bosom with less misgiving. This
is because the philosopher is in the grip of the Life Force. This Life
Force says to him "I have done a thousand wonderful things unconsciously
by merely willing to live and following the line of least resistance:
now I want to know myself and my destination, and choose my path; so
I have made a special brain--a philosopher's brain--to grasp this
knowledge for me as the husbandman's hand grasps the plough for me. And
this" says the Life Force to the philosopher "must thou strive to do
for me until thou diest, when I will make another brain and another
philosopher to carry on the work."

THE DEVIL. What is the use of knowing?

DON JUAN. Why, to be able to choose the line of greatest advantage
instead of yielding in the direction of the least resistance. Does a
ship sail to its destination no better than a log drifts nowhither? The
philosopher is Nature's pilot. And there you have our difference: to be
in hell is to drift: to be in heaven is to steer.

THE DEVIL. On the rocks, most likely.

DON JUAN. Pooh! which ship goes oftenest on the rocks or to the
bottom--the drifting ship or the ship with a pilot on board?

THE DEVIL. Well, well, go your way, Senor Don Juan. I prefer to be my
own master and not the tool of any blundering universal force. I know
that beauty is good to look at; that music is good to hear; that love is
good to feel; and that they are all good to think about and talk about.
I know that to be well exercised in these sensations, emotions, and
studies is to be a refined and cultivated being. Whatever they may say
of me in churches on earth, I kno
