The dilemma of traditional sex research lay in the unconscious, but unquestioningly assumed division into opposing drives and hereditary factors... The division into heterosexuality and homosexuality, into heterosexuals and homosexuals, is also an artifact that rests on a grave error, namely, on the assumption that a fundamentally different model is necessary to explain heterosexual and homosexual behavior. The entire investigation of etiology was ideologically loaded beforehand because it separated a segment of the sexual continuum and attempted to make analyses with the help of fundamentally different concepts.
