In Freud's extensive work, certain purely philosophical aspects will be studied. These aspects appear rather in his later works, as he had previously devoted a long time to therapeutic psychology. The major historical and social problems of humanity had been realized. Just like in the renowned work: "Civilization and Its Discontents," "Totem and Taboo," and his last philosophical work, "The Phenomenology of Religions (Moses and Monotheism)." "Most people do not really want freedom, because freedom entails responsibility, and most people are frightened of responsibility." (Sigmund Freud)
