These are a few notes and reflections on the early chapters of Luhmann’s Love as Passion: The Codification of Intimacy (English translation, 1986).
Marriage based on love, or the love marriage, evolved to solve a particular social problem, or to resolve a paradox. It isn’t just a natural given. The love marriage is characteristic of post-17th-century functionally differentiated society. Cultures today that still practice arranged marriage are not functionally differentiated. These are cultures in which everyone’s life is tightly bound to the family. Families remain together in the same place, if possible, and live the same kind of life, if possible, for generation after generation. Family cohesion takes precedence over individual happiness or self-determination. The family, as an autopoietic system, must survive generation after generation.
But the great love stories of literatures (e.g., Romeo and Juliet, Tristan and Isolde) are based on passion, and this passion has no regard for family ties or conventional moral norms. Love as passion can tear families apart, as parents disown children who have fallen in love with the wrong person or when a person cares more for their romantic partner than for their family of origin.
In functionally differentiated society, the individual (at least upon reaching adulthood) is cut loose from the family. She/he must make their own way in the world. The more functionally differentiated the society, the more the individual is on her/his own. A major factor is the complex economy of functionally differentiated society, which puts pressure on the traditional, multigenerational family (grown children move away to take jobs). The modern educational system also explicitly comes between parents and children.
For Luhmann, love as passion is a communication medium, and this passion is not really associated with marriage. Passionate love is supposed to happen outside of marriage, or is supposed to lead up to marriage but not last long thereafter. That’s why most fairy tale romances end at the wedding. Love as passion is a feature of the extramarital affair. Think of Prince Charles and Camilla. Passion is not bound to a moral code, and it has no regard for political, religious, economic norms, or for any other communication system. Passion as a communication medium reproduces itself until it can no longer do so. Passion is excessive and unreasonable.
Love, though not necessarily passion, has evolved to solve the problem of the operative closure of the psychic system. No one can know what another person is thinking or feeling, or how another psychic system processes information. But love is characterized by a willingness or effort to understand what another person is thinking and feeling. In order to truly understand another person, according to Luhmann,
One would have to participate in the other person’s self-referential information processing or at least be able to adequately reconstruct it, in order to be able to ‘understand’ how input works in him as information and how the person in turn reconnects output (what is said, for example) and information processing.
The communicative medium of love functions to make this seemingly improbable step possible. This is what is called ‘understanding’ in everyday parlance, and finds expression as the wish to be understood and–in the form of the complaint one is not sufficiently understood–is pushed beyond the bounds of the technically possible. (Love as Passion, p. 24.)
Love makes unrealistic or unreasonable demands on the other person’s capacity to understand. But love is not about reason.
The understanding issue also applies to close friendship, which is all about being understood and accepted by another person. Deep friendship is not so different than love; it just lacks the sexual aspect. Friendship, if we think of it as communication medium, may have evolved to deal with (not actually solve) the problem of psychic closure, or the sense of aloneness. Communication in general, or society, evolved to solve that problem. Passion is only one kind of love. In addition to intimate friendship, there is, of course parental love, etc. Each kind of love has its own semantics.
In love, a great deal is left unspoken. Luhmann argues that
love solves its own attendant communicative problems in a completely unique manner. To put it paradoxically, love is able to enhance communication by largely doing without communication. It makes use primarily of indirect communication, relies on anticipation and on having already understood. And love can thus be damaged by explicit communication, by discreet questions and answers, because such openness would indicate that something has not been understood as a matter of course. (25)
Every social system or structure has its own semantics. So there is a semantics of love that we are supposed to learn. These aren’t just internal, subjective experiences. We learn how to recognize the signs of “true love,” and we come to know what is expected.
Although passion breaks all the rules of morality and common sense, it is “nevertheless tolerated as a sort of disease and honored by being assigned a special role” (26).
