The Id, concept elaborated after 1920 in the Second Tpica Freudiana of the psychic device, is the instance that has the unconscious one as its equivalent. The Id is the original nucleus of the personality, in which if it finds the field, reservoir and psychic power plant pulsional. Referring to the pulses, Freud, to this height, already differentiates in pulses of life and death with the publication of Beyond the beginning of the Pleasure. The function of the Id is to reduce the tension, to increase the pleasure and to minimize the discomfort, understanding somatic stimulatons that demand of the psiquismo an immediate satisfaction.

Freud, in its article of 1915 on the Unconscious one, justifies the concept of unconscious as required, leaving of one of the estimated ones of that the data of the conscience present a great number of gaps.
