       What is Law?

      Before examining the language of the Constitution, in regard to Slavery, let us obtain a view of the principles, by virtue of which law arises out of those constitutions and compacts, by which people agree to establish government.

      To do this it is necessary to define the term law. Popular opinions are very loose and indefinite, both as to the true definition of law, and also as to the principle, by virtue of which law results from the compacts or contracts of mankind with each other.

      What then is Law? That law, I mean, which, and which only, judicial tribunals are morally bound, under all circumstances, to declare and sustain?

      In answering this question, I shall attempt to show that law is an intelligible principle of right, necessarily resulting from the nature of man; and not an arbitrary rule, that can be established by mere will, numbers or power.

      To determine whether this proposition be correct, we must look at the general signification of the term law.

      The true and general meaning of it, is that natural, permanent, unalterable principle, which governs any particular thing or class of things. The principle is strictly a natural one; and the term applies to every natural principle, whether mental, moral or physical. Thus we speak of the laws of mind; meaning thereby those natural, universal and necessary principles, according to which mind acts, or by which it is governed. We speak too of the moral law; which is merely an universal principle of moral obligation, that arises out of the nature of men, and their relations to each other, and to other things—and is consequently as unalterable as the nature of men. And it is solely because it is unalterable in its nature, and universal in its application, that it is denominated law. If it were changeable, partial or arbitrary, it would be no law. Thus we speak of physical laws; of the laws, for instance, that govern the solar system; of the laws of motion, the laws of gravitation, the laws of light, &c., &c.—Also the laws that govern the vegetable and animal kingdoms, in all their various departments: among which laws may be named, for example, the one that like produces like. Unless the operation of this principle were uniform, universal and necessary, it would be no law.

      Law, then, applied to any object or thing whatever, signifies a natural, unalterable, universal principle, governing such object or thing. Any rule, not existing in the nature of things, or that is not permanent, universal and inflexible in its application, is no law, according to any correct definition of the term law.

      What, then, is that natural, universal, impartial and inflexible principle, which, under all circumstances, necessarily fixes, determines, defines and governs the civil rights of men? Those rights of person, property, &c., which one human being has, as against other human beings?

      I shall define it to be simply the rule, principle, obligation or requirement of natural justice.

      This rule, principle, obligation or requirement of natural justice, has its origin in the natural rights of individuals, results necessarily from them, keeps them ever in view as its end and purpose, secures their enjoyment, and forbids their violation. It also secures all those acquisitions of property, privilege and claim, which men have a natural right to make by labor and contract.

      Such is the true meaning of the term law, as applied to the civil rights of men. And I doubt if any other definition of law can be given, that will prove correct in every, or necessarily in any possible case. The very idea of law originates in men’s natural rights. There is no other standard, than natural rights, by which civil law can be measured. Law has always been the name of that rule or principle of justice, which protects those rights. Thus we speak of natural law. Natural law, in fact, constitutes the great body of the law that is professedly administered by judicial tribunals: and it always necessarily must be—for it is impossible to anticipate a thousandth part of the cases that arise, so as to enact a special law for them. Wherever the cases have not been thus anticipated, the natural law prevails. We thus politically and judicially recognize the principle of law as originating in the nature and rights of men. By recognizing it as originating in the nature of men, we recognize it as a principle, that is necessarily as immutable, and as indestructible as the nature of man. We also, in the same way, recognize the impartiality and universality of its application.

      If, then, law be a natural principle—one necessarily resulting from the very nature of man, and capable of being destroyed or changed only by destroying or changing the nature of
