"There is a great deal more in homosexuality than a simple release of new levels of sexual permissiveness. True psychological mating is not only possible between individuals of the same sex, it is actually the rule in human interactions (whether sexual or not). How can two men, biologically alike, find a true difference between them through which mating can occur? The answer is simple but profound in its implications: through character specialization.

What this book says in effect is that character specialization is dominant over biological identity, and that therefore two men (or two women) can have a masculine-feminine interaction which can lay the basis for a true romantic union, pregnant with possibilities for creative self-development. The concept of masculinity and femininity, used in this way, has nothing to do with conventional masculine and feminine roles in our society. Such roles have social roots, not independent psychological ones."
