Throughout his distinguished career, Herbert Gutman has displayed a rare genius for dredging up the most gloriously obscure historical evidence and deriving from it new perspectives on the largest themes. The Black Family is another triumph of this kind: my awe of Professor Gutman’s energy and insight is enhanced by this volume. At the same time, Gutman makes clear that the volume is not demographic in its intent. Since my commentary is to be from a demographic perspective, I will take particular pains to direct this perspective to the purposes Gutman sets forth in The Black Family. These are identified by the author as discerning “what sustained common slave beliefs and behavior,” rather than merely documenting “regularities in behavior,” the latter being Gutman’s characterization of the results of the application of quantitative methods (1976). My task, then, is to examine the links that Gutman establishes between demographic argument and explanation, in his sense, and to assess their adequacy. No demographer, I suspect, would have undertaken the kind of investigation Gutman assays; but demographic skills would have served Gutman’s intentions. I will here try to be severe with this imposing volume, recognizing the importance and aptness of its central thesis, and the audacity of its author’s empirical reach, but questioning the adequacy of his demography to his own ends.
