Sigmund Freud was unanimously named the father of psychoanalysis. He discovered the main themes
of psychoanalysis and enforced gradually the practice of psychoanalysis as the neurosis therapy.
Being a Jew established in Vienna, in 1899 Freud published his most important work, The
Interpretation of Dreams, dated 1900.
It is the first scientific work dedicated to dreams and comprises a very wide and diverse summary that has always been amplified with successive editions.
It is the book in which Freud analyses his own dreams, presents the stages of dream elaboration and tries to explain the structure of psychic apparatus. Here Freud asserts that the dream is the royal pathway
to unconscious understanding.
Unconscious, repression/repressed, resistances, Oedipus complex, infantile sexuality are other important themes discovered
by Freud and addressed with the same methodical confidence.
