not seldom overlooked) makes the foundation of all his future
observations; nor can he advance a step without continual reference
to this double nature. We find him accordingly in the daily habit of
mentally distinguishing this person from that, as a moral being, and
of assigning to each a separate character; and this not voluntarily,
but simply because he cannot avoid it. Yet, by what does he presume
to judge of strangers? He will probably answer, By their general
exterior. And what is the inference? There can be but one; namely,
that there must be--at least to him--some efficient correspondence
between the physical and the moral. This is so plain, that the wonder
is, how it ever came to be doubted. Nor is it directly denied, except
by those who from habitual disgust reject the guesswork of the various
pretenders to scientific systems; yet even these, no less than others,
do practically admit it in their common intercourse with the world.
And it cannot be otherwise; for what the Creator has joined must have
some affinity, although the palpable signs may elude our cognizance.
And that they do elude it, except perhaps in a very slight degree,
is actually the case, as is well proved by the signal failure of all
attempts to reduce them to a science; for neither diagram nor axiom
has ever yet corrected an instinctive impression. But man does not
live by science; he feels, acts, and judges right in a thousand things
without the consciousness of any rule by which he so feels, acts, or
judges. And, happily for him, he has a surer guide than human science
in that unknown Power within him,--without which he had been without
knowledge. But of this we shall have occasion to speak again in
another part of our discourse.

Though the medium through which the soul acts be, as we have said, elusive
to the senses,--in so far as to be irreducible to any distinct form,--it
is not therefore the less real, as every one may verify by his own
