ABSTRACT
Sigmund Freud published hundreds of works over a career spanning sixty-three years, starting as a neuroscientist and ending as the father of psychoanalysis. While acknowledging that observation is fundamental to science, Freud later abandoned a strictly scientific approach to understanding the psyche, when from necessity, his speculations roved far beyond its limit of description. Freud's approach is dynamic in several senses, not only by positing a dynamic unconscious, but also in relation to theory, where he developed two broad approaches, comprising the earlier topographical theory and the later structural theory, to understanding the inner workings of the mind. Some of Freud's speculations on death have been introduced to marketing through the back door by Terror Management Theorists who have subjected them to the rigours of scientific method. Freud the scientist would no doubt be dismayed by the proliferation of different schools of psychoanalysis.
