Changes

In the Schema R: "...I as the ego-ideal, M as the signifier of the primordial object, and F as the position in O of the Name-of-the-Father. One can see how the homological fastening of the signification of S under the signifier of the phallus may affect the support of the field of reality delimited by the quadrangle MieI. The two other summits, e and i, represent the two imaginary terms of the narcissistic rapport, the ego and the specular image."

The preliminary question seems to be the one of the Other, whose presence commands everything else. It is the place from which the subject is confronted with the question of its existence (sexuation and death). What is the Other? Is it the unconscious where "it speaks?" Is it the place of memory that conditions the indestructibility of certain desires? Is it the place where the signifier of signifiers is the phallus? Is it the place symbolized by the Name-of-the-Father since "the Oedipus complex is consubstantial with the unconscious? When the paternal metaphor does not allow the subject to evoke the signification of the phallus, when the response to the call of the Name-of-the-Father is a lack of the signifier itself, then it is a case of psychosis.

"This applies to the metaphor of the Name-of-the-Father, that is, the metaphor that puts this Name in the place that was first symbolized by the operation of the mother's absence." It designates the metaphorical, substitutive, character of the Oedipus complex.
