"The exercise of the affectional function tends to satiety and exhaustion in the same way as all other physical or mental exercise; but if it is not carried to excess it is a permanent benefit. * * * The principle of Alphism will tend to diminish prostitution, not only by diminishing sexual intemperance, even if the principle is not at once accepted in practice to the full extent, thus diminishing the temptation of the present generation, and the hereditary temptation of future generations; but also by correcting the physiological error which has led astray so many, i. e., that total abstinence is not conducive to health, or to the highest physical pleasure, but that the ordinary physical relation is an essential feature in male existence. "To avoid misapprehension, these two theories should be clearly defined and the distinction between them explained. The doctrine of Alphism is confined to one principle, i. e., THE LAW OF ABSTINENCE EXCEPT FOR PROCREATION. Those who believe in this doctrine may be divided into different classes. Some believe in it as a matter of duty, to be enforced by precept and self-denial; and some believe in it as a matter of right, requiring no self-denial. In the latter is included the doctrine of 'Diana,' which may be defined as THE LAW OF SEXUAL SATISFACTION FROM SEXUAL CONTACT. In other words, Dianism is Alphism as the result of sexual equilibration." The general idea of Parkhurst, and those who have followed his teachings in some modified or adapted form, may be said to be based upon the following general proposition: That there is a dual function in the sexual relations, which may be stated as follows: (1) the function exercised from purely physiological causes, and which expresses the desire for the relation resulting in procreation; and (2) the function exercised from emotional causes, and which expresses what may be called the "affectional desire," i. e., the desire for the embrace, caress, fondling, and general companionship with the loved one of the other sex. The first one of these phases, i. e., the reproductive function, is manifested by the lower animals as well as by man, and is elemental and primitive in character. It is often manifested by man without the accompaniment of the affectional function, and at times seems to be almost entirely divorced from the idea of high human affection. The second one of these phases, i. e., the affectional function, usually accompanied the procreative function in the human sexual relation, at least in the highest forms of that relation. But also, it may be and often is manifested independently of the procreative function by men and women of refinement. In fact, it would seem to be the form of physical attraction accompanying the very highest phase of love, particularly in women.
