Evelyn Hooker "very tentatively suggests" that "homosexuality as a clinical entity does not exist" based on Rorschach experiments.

What are the psychological implications of the hypothesis that homo- sexuality is not necessarily a symptom of pathology? I would very tentatively suggest the following:
1. Homosexuality as a clinical entity does not exist. Its forms are as varied as are those of heterosexuality.
2. Homosexuality may be a deviation in sexual pattern which is within the normal range, psychologically. This has been suggested, on a biological level, by Ford and Beach (2).
3. The role of particular forms of sexual desire and expression in personality structure and development may be less important than has frequently been assumed. Even if one assumes that homosexuality represents a severe form of maladjustment to society in the sexual sector of behavior, this does not necessarily mean that the homosexual must be severely maladjusted in other sectors of his behavior. Or, if one assumes that homosexuality is a form of Severe maladjustment internally, it may be that the disturbance is limited to the sexual sector alone.
