couched in
unintelligible or only half-intelligible language, and almost totally
inapplicable to practice, have usually done duty for what is called a
system of moral philosophy. The authors or exponents of such theories
have the good fortune at once to avoid odium and to acquire a reputation
for profundity.

In the following pages, I shall attempt (1) to discriminate morality,
properly so called, from other sanctions of conduct; (2) to determine
the precise functions, and the ultimate justification, of the moral
sentiment, or, in other words, of the moral sanction; (3) to enquire how
this sentiment has been formed, and how it may be further educated and
improved; (4) to discover some general test of conduct; (5) to give
examples of the application of this test to existing moral rules and
moral feelings, with a view to shew how far they may be justified and
how far they require extension or reformation. As my subject is almost
exclusively practical, I shall studiously avoid mere theoretical
puzzles, such as is pre-eminently that of the freedom of the will,
which, in whatever way resolved, probably never influences, and never
will influence, any sane man's conduct. Questions of this kind will
always excite interest in the sphere of speculation, and speculation is
a necessity of the cultivated human intellect; but it does not seem to
me that they can be profitably discussed in a treatise, the aim of which
is simply to suggest principles for examining, for testing, and, if
possible, for improving the prevailing sentiment on matters of practical
morals.

To begin with the first division of my subject, How is morality,
properly so called, discriminated from other sanctions of conduct? By a
sanction I may premise that I mean any pleasure which attracts to as
well as any pain which deters from a given course of action. In books on
Jurisprudence, this word is usually employed to designate merely pains
or penalties, but this circumstance arises from the fact that, at least
in modern times, the law seldom has recourse to rewards, and effects its
ends almost exclusively by means of punishments. When we are considering
conduct, however, in its general aspects and not exclusively in its
relations to law, we appear to need a word to express any inducement,
whether of a pleasureable or painful nature, which may influence a man's
actions, and such a word the term 'sanction' seems conveniently to
supply. Taking the word in this exten
