By compiling instances of the kindness and benevolence of masters, Phillips proved to his satisfaction that slavery was a mild and permissive institution, the primary function of which was not so much to produce a marketable surplus as to ease the accommodation of the lower race into the culture of the higher. The critics of Phillips have tried to meet him on his own ground. Where he compiled lists of indulgences and benefactions, they have assembled lists of atrocities. Both methods suffer from the same defect: they attempt to solve a conceptual problem—what did slavery do to the slave?—by accumulating quantitative evidence... The only conclusion that one can legitimately draw from this debate is that great variations in treatment existed from plantation to plantation.
