"The whole question of blackness was discussed in a special essay by Jahiz of Basra (ca. 776-869), one of the greatest prose writers in classical Arabic literature and said by some of his biographers to be of partly African descent. Entitled "The Boast of the Blacks against the Whites,"" the essay purports to be a defense of the dark-skinned peoples-and especially of the Zanj, the blacks of East Africa-against their detractors, refuting the accusations commonly brought against them and setting forth their qualities and achievements, with a wealth of poetic illustration... To those who ask, "How is it that we have never seen a Zanji who had the intelligence even of a woman or of a child?" the answer, says Jahiz, is that the only Zanj they knew were slaves of low origin and from outlying and backward areas. If they judged by their experience of Indian slaves, would they have any notion of Indian science, philosophy, and art? Obviously not-and the same is true of the black lands. Jahiz also defends the equality of blacks as marriage partners and notes the paradox that discrimination against them first arose after the advent of Islam: At is part of your ignorance," he makes the blacks say, "that in the time of heathendom [i.e., in pre-Islamic Arabia] you regarded us as good enough to marry your women, yet when the justice of Islam came, you considered this wrong.""
