However, Joseph Christian Greer criticises Knight's account of his friendship with Wilson, considering it to be unreliable: "Half way through the text Knight claims to have become suddenly aware that Wilson promoted and espoused man-boy love as a viable sexuality and immediately lost interest in recording his subject's life ... His description of realizing Wilson's sexuality, though, rings particularly bogus on account of the fact that Wilson is quite open about his sexuality, even to the point of devoting numerous texts to intergenerational relationships. It seems certain that Knight would have been well aware of Wilson's sexuality long before starting to write his biography, and simply used it as an excuse to present his own work as superseding that of his former guru".
