The objection, to which this Kantian basis of Morals is at once and
directly exposed, lies in the fact that such an origin of a moral law
in us is impossible, because of its assumption that man would quite
of his own accord hit on the idea of looking about for, and inquiring
after, a law to which his will should be subject, and which should
shape its actions. This procedure, however, cannot possibly occur to
him of itself; at best it could only be after another moral; stimulus
had supplied the first impulse and motive thereto; and such a stimulus
would have to be positively operative, and real; and show itself to be
such, as well as spontaneously influence, indeed force its presence
upon, the mind. But anything of this sort would run counter to Kant's
assumption, which, according to the chain of reasoning above described,
is to be regarded as itself the origin of all moral conceptions--in
fact, the _punctum saliens_ of Morality. Consequently, as long as there
is no such antecedent incentive (because, _ex hypothesi_, there exists
no other moral stimulus but the process of thought already explained),
so long Egoism alone must remain as the plumb-line of human conduct,
as the guiding thread of the law of motivation; so long the entirely
empirical and egoistic motives of the moment, alone and unchecked,
must determine, in each separate case, the conduct of a man; since,
on this assumption, there is no voice to arrest him, neither does any
reason whatever exist, why he should be minded to inquire after, to
say nothing of anxiously searching for, a law which should limit and
govern his will. And yet it is only possible on this supposition that
he should think out the above remarkable piece of mental legerdemain.
It matters not how far we may care to put a strict and exact
interpretation on this Kantian process, or whether we choose to tone it
down to some dim, obscurely felt operation of thought. No modification
of it can attack the primary truths that out of nothing, nothing
comes, and that an effect requires a cause. The moral stimulus, like
every motive that effects the will, must in all cases make itself felt
spontaneously, and therefore have a positive working, and consequently
be real. And because for men the only thing which has reality is the
empirical, or else that which is supposed to have a possibly empirical
existence, therefore it follows that the moral stimulus cannot but
be empirical, and show itself as such of its own accord; and without
waiting for us to begin our search, it must come and press itself upon
us, and this with such force that it may, at least possibly, overcome
the opposing egoistic motives in all their giant strength. For Ethics
has to do with actual human conduct, and not with the _a priori_
building of card houses--a performance which yields results that no man
would ever turn to in the stern stress and battle of life, and which,
in face of the storm of our passions, would be about as serviceable as
