Sigmund Freud was a great Austrian psychologist, psychiatrist, and neurologist, known as the founder of psychoanalysis. Freud’s works made a major contribution to the science and culture of all humankind. Influenced by ideas and writings of great scholars and philosophers such as C. Darwin, E. Haeckel, A. Schopenhauer, F. Nietzsche, Freud developed an original method for treating mental disorders—psychoanalysis—that no one had used before him.
The most significant paradigm of Freud’s work—the culmination, according to many scholars, of his scientific creativity—is the development of a three-component structural model of the psyche, consisting of the “Id,” the “Ego,” and the “Superego.”
