This Essay is originated from a clinical experience with amputated people in a rehabilitation institution, where the corporeal experience has a great importance. Psychoanalysis establishes a place for the body which must be distinguished from the place it has in medical science, bypassing the organic/biological dimension, especialy because of the drive (Trieb) concept. Because of its helplessness, the human baby depends on some adult libidinal investment to construct a body-frontier. The adult, besides erotically marking its body, drawing the drive circuits, is necessary to allow a continuous experience of existence, and an image for identification, which serves the Ego and the object field development. This adult also helps in the construction of a symbolic matrix that shall make this body a desiring and speaking one. Among many drivedestinies, the experience of a loss requires the capacity of recreation through the work of mourning, which consists in taking back the libidinal investments from the lost objects to be able to invest them later in other objects. This research is about a peculiar loss: a body part. The experience of amputation requires a narcissistic reorganization which permits a new way of experimenting the body in its erogenous condition and, as a consequence, also the world. Nevertheless, bodily experience has, as well, a collective dimension. We must recognize that modernity brought, with the Industrial Revolution, something new to body experience. The technological advances made a body that is a hybrid form. The hybrid body is, at the same time: nature, techniques, science, drive economies, unconscious and discourse. This is how the prosthesis should be considered.
