Man is created a rational being; and therefore he is a subject of moral government, and accountable. Being rational and accountable, he is bound to improve his mind and intellect. With this design, his Creator has outstretched the heavens, and set the sun in his course, and hung out the burning jewels of the sky, and spread abroad the green earth, and poured out the seas, that he might steadily progress in knowledge. The slaves are men; they were born, then, as free as their masters; they cannot be property; and he who denies them an opportunity to improve their faculties, comes into collision with Jehovah, and incurs a fearful responsibility. But we know that they are not treated like rational beings, and that oppression almost entirely obliterates their sense of moral obligation to God or man. I fully coincide in opinion with the authoress of a work entitled, 'IMMEDIATE, NOT GRADUAL ABOLITION,' that the holder of a slave, whether he obtained him by purchase or by inheritance, is as guilty as the original thief.[K] The wretch who stole him could by no possible means acquire or transmit the right to make a slave of him, or to keep him in slavery. _He has a right to his liberty:_--through whatever number of transfers the usurpation of it may have passed, the right is undiminished. No man, says Algernon Sidney, can have a right over others, unless it be by them granted to him: That which is not just, is not law; and that which is not law, ought not to be in force: Whosoever grounds his pretensions of right upon usurpation and tyranny, declares himself to be an usurper and a tyrant--that is, an enemy to God and man--and to have no right at all: _That which was unjust in its beginning, can of itself never change its nature:_ HE WHO PERSISTS IN DOING INJUSTICE, AGGRAVATES IT, AND TAKES UPON HIMSELF ALL THE GUILT OF HIS PREDECESSORS: The right to be free is a truth planted in the hearts of men, and acknowledged so to be by all who have hearkened to the voice of nature, and disproved by none but such as through wickedness, stupidity, or baseness of spirit, seem to have degenerated into the worst of beasts, and to have retained nothing of men but the outward shape, or the ability of doing those mischiefs which they have learnt from their master the devil. The following is the indignant, emphatic, eloquent language of HENRY BROUGHAM, on the subject of slave property:
