In "Author's Preface to Third Edition" of his Contributions to the Theory of Sex, Freud emphasizes the empirical foundation of his essays, as well as the focus on considerations of therapeutic practice and purpose:
The dependence of this work on the psychoanalytic experiences which have determined the writing of it, shows itself not only in the selection but also in the arrangement of the material. A certain succession of stages was observed, the occasional factors are rendered prominent, the constitutional ones are left in the background, and the ontogenetic development receives greater consideration than the phylogenetic. For the occasional factors play the principal role in analysis, and are almost completely worked up in it, while the constitutional factors only become evident from behind as elements which have been made functional through experience, and a discussion of these would lead far beyond the working sphere of psychoanalysis.Not only this, in terms of focus and causality, Freud looks at "constitution" as the "precipitate of a former experience of the species to which the newer experience of the individual being is added as the sum of the occasional factors." That the essence of group behavior and group consciousness is observable is implicit here; that the nature of the individual consciousness and behavior is additive to or variation of an essential or historical "story" of sexuality is also implicit. From these statements, the reader can expect Freud's essays to focus on the individual as extrapolated from observable group behavior over time and representative of variation with a clearly defined field and/or changes in the observable structure of sexuality over time. The empirical nature of his theory is thus clear; the absolute of the conglomerate whole of observed behavior implicitly so.
In the subsequent introduction to the first essay in the actual text, entitled "The Sexual Aberrations", Freud describes the biological view of "sexual impulse" and then what he attributes to popular beliefs about the same.
The fact of sexual need in man and animal is expressed in biology by the assumption of a "sexual impulse." This impulse is made analogous to the impulse of taking nourishment, and to hunger. The sexual expression corresponding to hunger not being found colloquilly [sic], science uses the expression "libido."
Popular conception makes definite assumptions concerning the nature and qualities of this sexual impulse. It is supposed to be absent during childhood and to commence about the time of and in connection with the maturing process of puberty; it is supposed that it manifests itself in irresistible attractions exerted by one sex upon the other, and that its aim is sexual union or at least such actions as would lead to union. (I:Introduction)This is implicitly compared to the focus described in the aforementioned preface. Rather than an assumption of a biological impulse as explicitly imperative as the need to eat or the assumption of an idealized impulse that is a part of divine mythical union, Freud finds his explanation of the sexual impulse in the empirically observed behavior of the species over time and in the observed behavior or testimony of the individual.
What has become clear in these passages is not only his focus on empirical date and observed behavior but also the reliance on narrative mode as an indispensable part of the structure of psychotherapy, specifically the means of finding the causal story of the individual psyche and/or the story of subject's behavior (also object of study) in his setting.
Described in terms of narrative function, Freud clearly declares his independence from the "story" of biology or myth and chooses instead the "story" of the patient's behavior or psyche (ontogenetic view) as it relates to the story of the behavior of the group or category (phylogenetic view) as his point of departure:
The characteristics of the inversion in any individual may date back as far as his memory goes, or they may become manifest to him at a definite period before or after puberty.and:
(a) It must be considered that inversion was a frequent manifestation among the ancient nations at the height of their culture. It was an institution endowed with important functions. (b) It is found to be unusually prevalent among savages and primitive races, whereas the term degeneration is generally limited to higher civilization (I. Bloch). Even among the most civilized nations of Europe, climate and race have a most powerful influence on the distribution of, and attitude toward, inversion. (I:1A. Inversion)The causal, descriptive narrative of the psychotherapist is a reasoned unity: that the condition of inversion is congenital must be questioned, for example, due to the variety of its forms and the variety of the histories in their particulars of path and manifestation of traits or behavior at certain points of development or in conjunction with certain influences. Thus, congenital influence is taken out of the narrative scope.
The story of inversion, the narrative of the inverted individual is a multiple storyline, a host of variations, that, taken together, reveal an essence of sexuality that is biological, cultural and somehow graspable as an absolute set of variations.
The manifestation of homosexuality is therefore in no way connected to the narrative of sexuality as a free enterprise or to a penchant of consciousness to exist in a narrative mode of possibility, in which the self may be projected into a character, a setting and a storyline, on the basis of the basic functions of consciousness: the perception of self as something that is self-actualized on the basis of freedom that is narrative in structure.
How narrative may be a part of consciousness, how the story of one's sexuality might be one a trajectory of possibility within the individual consciousness, a possibility revealed through the narrative event itself, would never be the focus of a theory arising from the practice of psychotherapy, geared as it is toward an externally observable data.
