_derived_ Ends, which are susceptible of demonstrative proof; but
there must also be _ultimate_ Ends, for which no proof can be offered;
they must be received as self-evident, and their sole authority is the
person receiving them. In most of the practical sciences, the ends are
derived; the end of Medicine is Health, which is an end subsidiary to
the final end of human happiness. So it is with Navigation, with
Politics, with Education, and others. In all of them, we recognize the
bearing upon human welfare, or happiness, as a common, comprehensive,
and crowning end. On the theory of Utility, Morals is also governed by
this highest end.

Now, there can be no proof offered for the position that Happiness is
the proper end of all human pursuit, the criterion of all right
conduct. It is an ultimate or final assumption, to be tested by
reference to the individual judgment of mankind. If the assumption,
that misery, and not happiness, is the proper end of life, found
supporters, no one could reply, for want of a basis of argument--an
assumption still more fundamental agreed upon by both sides. It would
probably be the case, that the supporters of misery, as an end, would
be at some point inconsistent with themselves; which would lay them
open to refutation. But to any one consistently maintaining the
position, there is no possible reply, because there is no medium of
proof.

If then, it appears, on making the appeal to mankind, that happiness
is admitted to be the highest end of all action, the theory of Utility
is proved.

9. The judgment of Mankind is very generally in favour of Happiness,
as the Supreme end of human conduct, Morality included.
