The essence of Sigmund Freud's contribution to psychiatry lies in his construction of psychopathology based on psychotherapy. In his view, psychoanalysis is based on the act of remembering past experiences. As is well known, psychoanalysis emerged from hypnotherapy, which succeeded in recovering the memory of traumatic past events in hysterical patients. However, the invention of the psychoanalytic technique of remembering the past was not a direct result of this, for Freud was well aware of the fact that the act of remembering could not only facilitate the cure, but also instigate repetition, transference, and even delusion, which could prevent the cure. It was because he recognized these two opposite effects of remembering that he invented a new technique of listening to the patient's act of remembering with the understanding that this act was the basis of human dignity; this technique was psychoanalysis.
 One of the key findings of psychoanalytic remembering was that a mechanism similar to remembering was at work not only in the therapeutic process, but also in the pathogenetic process. Freud found that even after the traumatic event had become latent or inactive, it could be rekindled by various posterior events, be they environmental or maturational, and would reappear retroactively in symptomatic form. Freud called this mechanism "deferred action". When going back far into the earliest developmental period, the precipitating process of neurosis could be complicated but could also simultaneously reveal the real import of the infantile period in the human developmental history. The temporal dimension inherent to personality should make itself clear and be recovered. Freud's practice of psychoanalysis implies a vision that the act of remembering is what constitutes an innate sublimity for the self-awareness of human-beings.
