[13] The following is the preamble and the important enacting clause of this statute of 1740:
"Whereas, in his majesty's plantations in America, slavery has been introduced and allowed; and the people commonly called negroes, Indians, mulattos and mestizoes have (been) deemed absolute slaves, and the subjects of property in the hands of particular persons; the extent of whose power over such slaves ought to be settled and limited by positive laws, so that the slaves may be kept in due subjection and obedience, and the owners and other persons having the care and government of slaves, may be restrained from exercising too great vigor and cruelty over them; and that the public peace and order of this province may be preserved: Be it enacted, That all negroes, Indians, (free Indians in amity with this government, and negroes, mulattos and mestizoes, who are now free, excepted,) mulattos and mestizoes, who now are or shall hereafter be in this province, and all their issue and offspring born or to be born, shall be and they are hereby declared to be and remain forever hereafter absolute slaves, and shall follow the condition of the mother," &c.—Grimke, p. 163-4.

CHAPTER V.
THE DECLARATION OF INDEPENDENCE.
Admitting, for the sake of the argument, that prior to the revolution, slavery had a constitutional existence, (so far as it is possible that crime can have such an existence,) was it not abolished by the declaration of independence?
The Declaration was certainly the constitutional law of this country for certain purposes. For example, it absolved the people from their allegiance to the English crown. It would have been so declared by the judicial tribunals of this country, if an American, during the revolutionary war or since, had been tried for treason to the crown. If, then, the declaration were the constitutional law of the country for that purpose, was it not also constitutional law for the purpose of recognizing and establishing, as law, the natural and inalienable right of individuals to life, liberty and the pursuit of happiness? The lawfulness of the act of absolving themselves from their allegiance to the crown, was avowed by the people of the country—and that too in the same instrument that declared the absolution—to rest entirely upon, and to be only a consequence of the natural right of all men to life, liberty and the pursuit of happiness. If, then, the act of absolution was lawful, does it not necessarily follow that the principles that legalized the act, were also law? And if the country ratified the act of absolution, did they not also necessarily ratify and acknowledge the principles which they declared legalized the act?
It is sufficient for our purpose, if it be admitted that this principle was the law of the country at that particular time, (1776)—even though it had continued to be the law only for a year, or even a day. For if it were the law of the country even for a day, it freed every slave in the country—(if there were, as we say there were not, any legal slaves then in the country.) And the burden would then be upon the slaveholder to show that slavery had since been constitutionally established. And to show this, he must show an express constitutional designation of the particular individuals, who have since been made slaves. Without such particular designation of the individuals to be made slaves, (and not even the present constitutions of the slave States make any such designation,) all constitutional provisions, purporting to authorize slavery, are indefinite, and uncertain in their application, and for that reason void.
But again. The people of this country—in the very instrument by which they first announced their independent political existence, and first asserted their right to establish governments of their own—declared that the natural and inalienable right of all men to life, liberty and the pursuit of happiness, was a "self-evident truth."
Now, all "self-evident truths," except such as may be explicitly, or by necessary implication, denied, (and no government has a right to deny any of them,) enter into, are taken for granted by, and constitute an essential part of all constitutions, compacts and systems of government whatsoever.—Otherwise it would be impossible for any systematic government to be established; for it must obviously be impossible to make an actual enumeration of all the "self-evident truths," that are to be taken into account in the administration of such a government. This is more especially true of governments founded, like ours, upon contract. It is clearly impossible, in a contract of government, to enumerate all the "self-evident truths" which must be acted upon in the administration of law. And therefore they are all taken for granted, unless particular ones be plainly denied.
