Shreds and scraps of real law, stuck on upon that imaginary ground, compose the furniture of every national code. What follows?—that he who, for the purpose just mentioned or for any other, wants an example of a complete body of law to refer to, must begin with making one.

There is, or rather there ought to be a logic of the will, as well as of the understanding: the operations of the former faculty, are neither less susceptible, nor less worthy, then those of the latter, of being delineated by rules. Of these two branches of that recondite art, Aristotle saw only the latter: succeeding logicians, treading in the steps of their great founder, have concurred in seeing with no other eyes. Yet so far as a difference can be assigned between branches so intimately connected, whatever difference there is, in point of importance, is in favour of the logic of the will. Since it is only by their capacity of directing the operations of this faculty, that the operations of the understanding are of any consequence.

Of this logic of the will, the science of law, considered in respect of its form, is the most considerable branch,—the most important application. It is, to the art of legislation, what the science of anatomy is to the art of medicine: with this difference, that the subject of it is what the artist has to work with, instead of being what he has to operate upon. Nor is the body politic less in danger from a want of acquaintance with the one science, than the body natural from ignorance in the other. One example, amongst a thousand that might be adduced in proof of this assertion, may be seen in the note which terminates this volume.

Such then were the difficulties: such the preliminaries:—an unexampled work to achieve, and then a new science to create: a new branch to add to one of the most abstruse of sciences.

Yet more: a body of proposed law, how complete soever, would be comparatively useless and uninstructive, unless explained and justified, and that in every tittle, by a continued accompaniment, a perpetual commentary of reasons: which reasons, that the comparative value of such as point in opposite directions may be estimated, and the conjunct force, of such as point in the same direction may be felt, must be marshalled, and put under subordination to such extensive and leading ones as are termed principles. There must be therefore, not one system only, but two parallel and connected systems, running on together. the one of legislative provisions, the other of political reasons, each affording to the other correction and support.

Are enterprises like these achievable? He knows not. This only he knows, that they have been undertaken, proceeded in, and that some progress has been made in all of them. He will venture to add, if at all achievable, never at least by one, to whom the fatigue of attending to discussions, as arid as those which occupy the ensuing pages, would either appear useless, or feel intolerable. He will repeat it boldly (for it has been said before him), truths that form the basis of political and moral science are not to be discovered but by investigations as severe as mathematical ones, and beyond all comparison more intricate and extensive. The familiarity of the terms is a presumption, but is a most fallacious one, of the facility of the matter. Truths in general have been called stubborn things: the truths just mentioned are so in their own way. They are not to be forced into detached and general propositions, unincumbered with explanations and exceptions. They will not compress themselves into epigrams. They recoil from the tongue and the pen of the declaimer. They flourish not in the same soil with sentiment. They grow among thorns; and are not to be plucked, like daisies, by infants as they run. Labour, the inevitable lot of humanity, is in no track more inevitable than here. In vain would an Alexander bespeak a peculiar road for royal vanity, or a Ptolemy, a smoother one, for royal indolence. There is no King's Road, no Stadtholder's Gate, to legislative, any more than to mathematic science.

Chapter I

OF THE PRINCIPLE OF UTILITY

I. Nature has placed mankind under the governance of two sovereign masters, pain and pleasure. It is for them alone to point out what we ought to do, as well as to determine what we shall do. On the one hand the standard of right and wrong, on the other the chain of causes and effects, are fastened to their throne. They govern us in all we do, in all we say, in all we think: every effort we can make to throw off our subjection, will serve but to demonstrate and confirm it. In words a man may pretend to abjure their empire: but in reality he will remain subject to it all the while. The principle of utility recognizes this subjection, and assumes it for the foundation of that system, the object of which is to rear the fabric of felicity by the hands of reason and of law. Systems which attempt to question it, deal in sounds instead of sense, in caprice instead of reason, in darkness instead of light.

But enough of metaphor and declamation: it is not by such means that moral science is to be improved.

II. The principle of utility is the foundation of the present work: it will be proper therefore at the outset to give an explicit and determinate account of what is meant by it. By the principle of utility is meant that principle which approves or disapproves of every action whatsoever, according to the tendency it appears to have to augment or diminish the happiness of the party whose interest is in question: or, what is the same thing in other words, to promote or to oppose that happiness. I say of every action whatsoever, and therefore not only of every action of a private individual, but of every measure of government.
