It is true, he was a slaveholder; and hence his theory was better than his practice. It is apparent, moreover, that he had clearer views of the impolicy of the slave-system, than of its guilt. But he never dishonored his judgement, or perverted his good sense, by attempting to prove the lawfulness of holding the colored race in bondage."
