2. The Principles.
Every science only extends as far as its principles. If one starts with matter, form, and privation, one can only give a scientific account of the causes and properties of mobile being. Theology of the Body begins from the phenomenological method. That is, in an attempt to meet people where they are at, it appeals to most people’s experience.
The thing is, if one begins with experience, the end will be a scientific explanation of people’s experience. No more, no less. And this is useful. But again, it is not going to answer the nitty-gritty moral questions. Questions about morality are questions about the proper ordering of man’s voluntary acts. How men experience themselves as acting persons is not the proper guide. Some metaphysics will be needed; there will have to be some understanding of what man’s final end is, what the ends of the powers of the soul are, which faculties of the soul are the most important, indeed, what makes man to be man.
The theologian Bernard Lonergan (NOTE: I am referring to the early Bernard Lonergan, when he remained a speculative Thomist; not the later Bernard Lonergan, who turned to a more phenomenological method) mentions this fact in critiquing the work of Herbert Doms, one of the theologians credited, along with Dietrich von Hildebrand, with bringing a more personalistic approach to marital morality. Lonergan says:
…marriage is more an incorporation of the finality of sex than of sex itself. Of course, it it just the opposite that seems true to phenomenologist scrutiny, for that ignores the metaphysical principle that what is prior quoad se is posterior quoad nos, and that the more ultimate final cause enters more intimately into the nature of a thing than the more proximate…This, I think, touches upon a fundamental methodological error in the analysis presented by Dr. Doms. I agree that sex is to be distinguished from fecundity, as impotence from sterility. I agree with the validity of the question, What is the ontological significance of bisexuality [i.e., the distinction of male and female]. It is only a terminological difference when he asserts that the meaning of marriage is union and I say that the act and end of bisexuality is union, or when in different ways we both place two ends beyond this union. But when he speaks of this meaning of union as immanent, intrinsic, immediate, I distinguish: in the chronological order of human knowledge or of the development of human appreciation, the union is first; but in the ontological order the ordinations to the ends are more immanent, more intrinsic, more immediate to the union than the union itself. For what is first in the ontological constitution of a thing is not the experiential datum but, on the contrary, what is known in the last and most general act of understanding with regard to it; what is next, is the next most general understanding, etc. Thus the proximate end of bisexuality is union; but of its nature, bisexuality is an instrument of fecundity, so that the end of fecundity is more an end of bisexuality than is union… ["Finality, Love, Marriage," Theological Studies 4 (1943)]
Prof. Janet Smith also makes an allusion to this principle in her most recent defense of Christopher West.
Now, in actual practice (as far as I can tell), no TOB advocate actually remains purely at the level of phenomena. We are Catholics, and we have a moral tradition. We all know that certain things are right, and certain things are wrong. And most TOB advocates resort to metaphysical presuppositions at one time or another. For instance, many that I have been exposed to point out that the actions of the body have objective (and not just subjective) significative power. But that only proves one thing: at some point, you have to get to the nature of things. Why is contraception so often referred to as “a lie”? Because in the nature of things, the spouses are not giving something that is proper to marriage. There is something that they are doing that does not belong to the very raison d’etre of that particular union of man and woman called marriage, a union whose form is not made by their own wills (though it is entered into by their own wills), but somehow belongs to the nature of the rational animal. In the end, it presupposes what marriage is for, and what sex is for. But the phenomena do not tell you that.
I must head off one objection: Does not St. Thomas himself say all knowledge begins in the senses? Does not every science begin with experience? This is true. But for St. Thomas, the senses are the beginnings (initia) of intellectual knowledge, not its principles (principia). The senses provide the phantasm, which is knowable in potency, but it is the simple light of the agent intellect that renders a thing’s nature known in act. Knowledge has its beginnings in experience, which is of the particular, but it ends in understanding, which is of the universal. The agent intellect automatically perceives the common in the many, in a confused manner at first, but then, as reason continues its discourse, it can proceed to a more specific concept, and even formulate a definition. This is not phenomenology. Phenomenology looks at men’s experiences and simply describes them, as men’s experiences. Phenomenologists may believe or not believe that there is an actual bridge between the phenomena and the things. A consideration of the things themselves as objects is merely bracketed out. The phenomenological method itself prefers to reflect on the experience itself, as it is in the knowing subject. This has its uses. But it does not answer the questions of morality. At best, it will only tell us a bit of what’s going on in our psyche as we perform good or evil acts.
The future Pope John Paul II himself admitted the limits of the phenomenological method:
If ethical experience essentially consists in this specific becoming of the person, then the only interpretation of it that can be considered adequate is one that apprehends and expresses this ethical becoming. This is what also leads me to believe that we should consider the view of the human act developed by Thomas Aquinas an adequate interpretation of ethical experience. I do not intend here to analyze his view or its adequacy in relation to the complete structure of ethical experience. I only want to draw attention to its origin. St. Thomas based his view of the human act on Aristotle’s theory of potency and act, a theory by which the philosophy of being explains all changes that take place in beings. Every change, whether it is of a material or spiritual nature, whether it takes place in an organism or in the psyche, can be said—in an analogical sense, of course—to be a form of passage from potency to act. A conscious human act is for St. Thomas not merely a stage upon which ethical experience is enacted. It is itself an ethical experience because it is an act of will. An act of will is for St. Thomas a passage from potency, since the will is a faculty (potentia) of the soul. A separate study would be needed to show how the ethical becoming of the person is reflected in this view as a whole.
Nevertheless, the reasons presented in this last part of the essay clearly show that phenomenology of the will alone does not suffice for interpreting ethical experience, even if this phenomenology happens to be as much in harmony with experience as that upon which Ach and his whole experimental school are based. Phenomenology can indirectly assist us in overcoming certain errors in views of the will that arise from an improper relation to the empirical facts, but it cannot serve as a tool for the sort of interpretation of ethical experience upon which ethics as a normative science is based.
