"So what was abolitionism in such contexts? Can we at all use here this loaded, essentially foreign, term in a meaningful, historical sense ? Should we bother to ? True, some historians might find it worthwhile to study lone abolitionist voices in an otherwise solid anti-abolition discourse. But then, some historians would always insist that the unrepresentative is important in and of itself, regardless of its social and political significance. Even if we examine with good intentions the scant evidence that Clarence-Smith himself provides in his book, we cannot but conclude how very few and very far between such voices indeed were. Considered within the huge dimensions of the Islamic World and the extended period of time allowed by the author for these voices to have emerged, the phenomenon appears so marginal and ephemeral that it cannot possibly deserve to be called a "sentiment", let alone constitute a Subversive current' or be described as a Movement'. Why, then, we may ask, does Clarence-Smith insist on this unpromising line of investigation and rather forced research agenda.... Also, if scholars were to undertake, in earnest and honesty, extensive studies of anti-enslavement manifestations in Islamic societies, their work would most probably reinforce the kind of negative view of ' Islam' that Clarence-Smith is so eager to revise and reconstruct."
