The given point of view, and the method of treatment announced, are
themselves sufficient to indicate that in this ethical book no precepts,
no doctrine of duty must be looked for; still less will a general moral
principle be given, an universal receipt, as it were, for the production
of all the virtues. Neither shall we talk of an “_absolute ought_,” for
this contains a contradiction, as is explained in the Appendix; nor yet of
a “_law of freedom_,” which is in the same position. In general, we shall
not speak at all of “ought,” for this is how one speaks to children and to
nations still in their childhood, but not to those who have appropriated
all the culture of a full-grown age. It is a palpable contradiction to
call the will free, and yet to prescribe laws for it according to which it
ought to will. “Ought to will!”—wooden iron! But it follows from the point
of view of our system that the will is not only free, but almighty. From
it proceeds not only its action, but also its world; and as the will is,
so does its action and its world become. Both are the self-knowledge of
the will and nothing more. The will determines itself, and at the same
time both its action and its world; for besides it there is nothing, and
these are the will itself. Only thus is the will truly autonomous, and
from every other point of view it is heteronomous. Our philosophical
endeavours can only extend to exhibiting and explaining the action of men
in its inner nature and content, the various and even opposite maxims,
whose living expression it is. This we shall do in connection with the
preceding portion of our work, and in precisely the same way as we have
hitherto explained the other phenomena of the world, and have sought to
bring their inmost nature to distinct abstract knowledge. Our philosophy
will maintain the same _immanency_ in the case of action, as in all that
we have hitherto considered. Notwithstanding Kant’s great doctrine, it
will not attempt to use the forms of the phenomenon, the universal
expression of which is the principle of sufficient reason, as a
leaping-pole to jump over the phenomenon itself, which alone gives meaning
to these forms, and land in the boundless sphere of empty fictions. But
this actual world of experience, in which we are, and which is in us,
remains both the material and the limits of our consideration: a world
which is so rich in content that even the most searching investigation of
which the human mind is capable could not exhaust it. Since then the real
world of experience will never fail to afford material and reality to our
ethical investigations, any more than to those we have already conducted,
nothing will be less needful than to take refuge in negative conceptions
void of content, and then somehow or other make even ourselves believe
that we are saying something when we speak with lifted eyebrows of
“absolutes,” “infinites,” “supersensibles,” and whatever other mere
