Selfishness shows itself, in a special manner, in the inordinate action of the desires. Desire, it is well understood, is a distinct tendency or principle of
the human mind, known by the circumstances of its origin and by its
being distinguished in our consciousness from every other state of mind;
but it is worthy of notice, that it exists, and that it exhibits itself
under different and important modifications. In its connection with the
wants and laws of the physical system, it assumes, for instance, the
well known modification of the Appetites; a class of natural principles,
which are necessary and right in their origin, but which are frequently
perverse and debasing in their application. The desire of personal
happiness, the desire of society, the desire of knowledge, the desire of
esteem, and others which might be mentioned, are other modifications of
the same general principle; less closely connected with the physical
nature than the appetites are, and distinguished for this, and for other
reasons, as the Propensive principles or the Propensities. But these,
as well as the appetites, are subject, under the influence of inordinate
self-love, to a perverted action; not so gross perhaps and so debasing,
but still not less real and not less sinful. Our natural Affections
also, the affection of parents for their children and of children for
their parents and other similar affections, (a still higher and more
noble class of natural principles than those which have just been
mentioned,) have desire for their basis, and may very properly be
regarded as its modifications.
Each and all of these principles or
classes of principles are liable to assume an inordinate and wrong
position; and in point of fact it cannot be doubted, that they do
frequently and almost continually go astray under various circumstances
and in various degrees. But it seems to me, so far as a judgment can be
formed in the case, that they never assume a wrong position, that they
never become perverted and sinful, except under the influence, (an
influence as secret and extensive, as it is baleful,) of the vice or
crime of selfishness.
Even when these principles err by undue weakness as well as by excess,
which is sometimes the case, the result can be traced to the influence
of the same inordinate love of self, operating in a different direction,
but destroying by what it takes away as well as by what it gives.
