Sexuality has been at the centre of interest of psychoanalysis. Is it still today? What was the novelty Freud brought into this domain? There is no doubt that sexuality was also at the centre of Freud's interest. He used bits and pieces of the then new observations and the discourse of the contemporary sexologists to lay the foundation for his own new science. But what were the news he put before the eyes of a stunned world of 1905, a century ago, provoking much admiration and much resistance?
First let us remember that at the time of the publication of The Interpretation of Dreams (1900a), he wrote to Fliess: “A theory of sexuality might well be the dream book's immediate successor” and its complement (1905d, p. 129, Letter 128). Why this? We may speculate that discovering the sexual nature and the unconscious wish at the root of the dreams led him more than other former experiences with sexuality to the elaboration of its theory. The instinctual drives became the foundation of fantasy life, and this has remained perhaps the most important element in psychoanalytic practice until today. It is perhaps no coincidence that he always tried to keep these two books, the one on dreams and that on sexuality—and only these—up to date. They were the pillars of his doctrine.In general terms, on the cultural scene, he allowed people to speak about sexuality. The author of the Aphasia Studies created a language and, together with others such as Krafft-Ebing, supplied terms like masochism, sadism, narcissism, inhibition, and many others, allowing what one thought about sex to be formulated. He brought the sexually determined contents out of the closet of medical consultation-room and the Latin jargon into everyday language. In a little circle of men—who also had some sexual problems of their own, as in the case of Stekel, Ferenczi, Jones, Tausk, Gross, Jung, and others—the sensitivity for this dimension was brought to life so that a scientific discourse could slowly emerge, partly borrowed from the sexologists.

great mobilisation that destroyed the old models.
Design is the method of putting form and content together. Design,
just as art, has multiple definitions; there is no single definition.
Design can be art. Design can be aesthetics. Design is so simple, thats
why it is so complicated.

As part of the creational category of design patterns, the
Factory Method pattern is involved with creating
something. In the case of the Factory Method, the
something created is a product that is not tied to
the class that creates it. Instead, in order to maintain loose coupling,
the client makes the request through a factory. The factory then makes the
requested product. Another way of thinking about it is that the Factory
Method frees the product from the requestor. Figure5-1 shows a class
diagram of the Factory Method.
