To begin, Wiencek briefly addresses and dismisses the claim that Washington fathered a child with Venus, (a slave owned by Washingtong's brother, John Augustine). According to Wiencek, the President was likely sterile and such an affair would have been out of character for a man who prided himself on "self-control."
Wiencek's real focus in An Imperfect God is Washington's personal and political position regarding emancipation. The primary ground for Wiencek's argument is Washington's will and a selection of private letters that elaborate a plan for providing land and means for his freed laborers. The will in particular offers powerful evidence of Washington's true intentions, including explicit declarations manumitting Washington's slaves after his death. As Wiencek shows, the document punctuated a long period of equivocation.
An Imperfect God is an imperfect book. Wiencek's occasional first-person accounts of his field research, including discussions with descendants of Washington, feel strangely out of place in what is elsewhere a straightforward biography punctuated with digressions into Washington's larger historical context. Further, Wiencek sometimes dabbles in hagiography and is willing to excuse much in a man who was a slaveholder his entire life. Yet, Wiencek is right to point out the distinctions of Washington among the slaveholding Founding Fathers. Readers can only imagine along with Wiencek the national tragedy that could have been averted had Washington provided the great example of emancipation while in office. --Patrick O'Kelley
