So far as the laws of conduct are determined by the intellect, I
apprehend that they belong to science, and to that part of science which
is called morality. But the engagement of the affections in favour of
that particular kind of conduct which we call good, seems to me to be
something quite beyond mere science. And I cannot but think that it,
together with the awe and reverence, which have no kinship with base
fear, but arise whenever one tries to pierce below the surface of
things, whether they be material or spiritual, constitutes all that has
any unchangeable reality in religion.
