reconciled to our brethren whom we held in bondage? Should we not have loosed their chains, and broken their fetters? Or if the difficulties and dangers of such an experiment prohibited the attempt during the convulsions of a revolution, is it not our duty to embrace the first moment of constitutional health and vigour, to effectuate so desirable an object, and to remove from us a stigma, with which our enemies will never fail to upbraid us, nor our consciences to reproach us? To form a just estimate of this obligation, to demonstrate the incompatibility of a state of slavery with the principles of our government, and of that revolution upon which it is founded, and to elucidate the practicability of its total, though gradual, abolition, it will be proper to consider the nature of slavery, its properties, attendants, and consequences in general; its rise, progress, and present state not only in this commonwealth, but in such of our sister states as have either perfected, or commenced the great work of its extirpation; with the means they have adopted to effect it, and those which the circumstances and situation of our country may render it most expedient for us to pursue, for the attainment of the same noble and important end.[3] [Footnote 1: The subject of a preceding Lecture, with which the present was immediately connected, was, An Enquiry into the Rights of Persons, as Citizens of the United States of America.] [Footnote 2: The American standard, at the commencement of those hostilities which terminated in the revolution, had these words upon it----AN APPEAL TO HEAVEN!] [Footnote 3: The Author here takes the liberty of making his acknowledgments to the reverend Jeremiah Belknap, D.
