This article examines the father’s limits in organizing the economy of the instincts. It arguments that the paternal function structures the unconscious as a language, defining only one sex, the phallic, and demonstrates the impossibility of defining The Woman. The subject who is imprisoned by the signifying order is impeded to have access to the object and the woman embodies the suplement that the phallus lacks. This manner of organizing creates an infinite space between the lacking beings and, for this reason, the text follows the logic of compacity developed by Lacan to demonstrate the contingency of the loving encounter. It also justifies why the analyst is supported by the feminine position, adopting the “semblance” of the object that is lacking to the phallic function.
