Sigmund Freud and understanding the mind
Sigmund Freud is known as the father of psychoanalysis. This course is not about psychoanalysis, although we make reference to ideas such as the unconscious mind that Freud first introduced. It is therefore impossible to talk about the fundamentals of consciousness without mentioning Freud because of his seminal contribution to the field.
It is less well known that Freud first worked as a neuroscientist. Starting in the 1870s, Freud began a 20-year-long career practising as a neuroscientist. As a neuroscientist, Freud found the prevailing methods of mapping complex mental functions limiting. He was unable to sketch a model of the brain mechanisms that underlay the complex mental phenomena he was seeing in his patients - at least he was not able to apply a scientific method - and thus he abandoned neuroscientific methods in favour of developing a psychoanalytical model. While his model had shortcomings, it was at least empirical in that he studied and directly interacted with human subjects and their disorders. Freud’s theory focused on an inner world of unconscious conflict - where the mind generates wishes that are repressed before we are aware of them. He found that bringing these unconscious wishes to the fore allows for patients to notice and deal with them.
We must acknowledge the limitations of the methods used by Freud but also appreciate the limitations of neuroscientific methods of the present time. Modern neuroscience has the opportunity to use powerful tools such as brain imaging techniques and experimental rigour to test some of the intriguing ideas propounded by psychoanalysis. What psychoanalysis stresses is the importance of subjective experiences and the notions of the self to understand the mind - something that neuroscience shied away from.
