Among the evils corrected or subdued, either by the general influence of Christianity on the minds of men, or by particular associations of Christians, the African[A]. Slave Trade appears to me to have occupied the foremost place. The abolition of it, therefore, of which it has devolved upon me to write the history, should be accounted as one of the greatest blessings, and as such should be one of the most copious sources of our joy: indeed, I know of no evil, the removal of which should excite in us a higher degree of pleasure. For, in considerations of this kind, are we not usually influenced by circumstances? Are not our feelings usually affected according to the situation, or the magnitude, or the importance of these? Are they not more or less elevated, as the evil under our contemplation has been more or less productive of misery, or more or less productive of guilt? Are they not more or less elevated again, as we have found it more or less considerable in extent? Our sensations will undoubtedly be in proportion to such circumstances, or our joy to the appreciation or mensuration of the evil which has been removed. [Footnote A: Slavery had been before annihilated by Christianity; I mean in the West of Europe, at the close of the twelfth century] To value the blessing of the abolition as we ought, or to appreciate the joy and gratitude which we ought to feel concerning it, we must enter a little into the circumstances of the trade. Our statement, however, of these needs not be long: a few pages will do all that is necessary! A glance only into such a subject as this will be sufficient to affect the heart,--to arouse our indignation and our pity,--and to teach us the importance of the victory obtained. The first subject for consideration, towards enabling us to make the estimate in question, will be that of the nature of the evil belonging to the Slave Trade. This may be seen by examining it in three points of view. First, as it has been proved to arise on the Continent of Africa, in the course of reducing the inhabitants of it to slavery. Secondly, in the course of conveying them from thence to the lands or colonies of other nations. And, thirdly, in continuing them there as slaves.
