The French Catholic writer Marc Oraison, who is known for his well-argued liberal moral views, offers here an expert but quite controversial discussion of homosexuality, based on twenty years experience working with homosexuals as a combination priest, physician, and psychologist. Strictly speaking, he points out, homosexuality does not exist; only homosexual individuals do, and the many case histories he uses as illustrations demonstrate that the types and circumstances vary so widely that any single image is bound to distort. He deems a homosexual orientation neither an illness nor a matter of choice, but he does consider it the result of arrested psychological development, and thus a condition for which professional help is often needed. Since the causes are primarily psychological and environmental (not genetic or hormonal), solutions to the difficulties it presents come best through psychotherapy, though the precise goal of therapy must be determined individually. A balanced, informed, sympathetic account--though perhaps restricted in perspective--this makes a good introduction to the subject, especially for liberal Catholics who share Oraison's general viewpoint. It won't please either moral traditionalists or gay militants, but he regards both groups as insensitive to the concrete realities of homosexual experience.
