a practical purpose
of the highest moment,--the mental and moral culture of every rational
being. The other was to shew the close and important relation which
exists between this science and the doctrines of revealed religion, and
the powerful evidence which is derived, for the truth of both, from the
manner in which they confirm and illustrate each other. These two
sources of knowledge cannot be separated, in the estimation of any one
who feels the deep interest of the inquiry, and seriously prosecutes the
important question,--what is truth. If we attempt to erect the
philosophy of morals into an independent science, we shall soon find
that its highest inductions only lead us to a point beyond which we are
condemned to wander in doubt and in darkness. But, on the other hand, by
depreciating philosophy, or the light which is derived from the moral
impressions of the mind, we deprive ourselves of a most important source
of evidence in support of revelation. For it is from these impressions,
viewed in connexion with the actual state of man, that we learn the
necessity, and the moral probability, of a revelation; and it is by
principles existing in the mind that we are enabled to feel the power of
that varied and incontrovertible evidence, by which revelation comes to
the candid inquirer with all the authority of truth.
