How Did Freud Invert Platonic Philosophy in His Scientific Psychology?

Psychoanalysis is a theoretical and therapeutic system in psychology founded by Freud. It emphasises that the conscious and unconscious parts of the mind affect one another, and that this process can influence human capacities and functioning. For this reason, this field came to be called depth psychology and, for the first time, introduced the human unconscious into psychoanalysis as a paradigm and a fundamental element.

Freud regarded himself as the discoverer of the unconscious and of its influence on human behaviour. Yet this division of the mind into different domains is far older than Freud and can be traced back to Plato’s theories.
Plato envisaged three domains within the structure of the human psyche:
The first is transcendent rationality, a form of higher wisdom in the human being that connects us to a higher truth; this higher wisdom is itself of the nature of Logos, or a greater reason.
The middle domain consists of higher human emotions that guide the person toward greatness, such as the desire for honour and nobility.
The third domain contains bodily and material needs and desires, which can be governed by higher emotions and higher wisdom.

Freud did not believe in anything beyond human existence, and in his theories everything has its roots within the human psyche rather than outside it.
In the Platonic view, the human being is a Logos-centred and transcendence-oriented being, and human history is likewise a history of transcendence.
