Psyche (psychology) in the context of "On the Soul"

Sigmund Freud (born Sigismund Schlomo Freud; 6 May 1856 – 23 September 1939) was an Austrian neurologist and the founder of psychoanalysis, a clinical method for evaluating and treating pathologies seen as originating from conflicts in the psyche, through dialogue between patient and psychoanalyst, and the distinctive theory of mind and human agency derived from it.

Freud was born to Galician Jewish parents in the Moravian town of Freiberg, in the Austrian Empire. He qualified as a doctor of medicine in 1881 at the University of Vienna. Upon completing his habilitation in 1885, he was appointed a docent in neuropathology and became an affiliated professor in 1902. Freud lived and worked in Vienna, having set up his clinical practice there in 1886. Following the German annexation of Austria in March 1938, Freud left Austria to escape Nazi persecution. He died in exile in the United Kingdom in September 1939.

Human behavior is the potential and expressed capacity (mentally, physically, and socially) of human individuals or groups to respond to internal and external stimuli throughout their life. Behavior is driven by environmental and genetic factors that affect an individual. Behavior is also driven, in part, by thoughts and feelings, which provide insight into individual psyche, revealing such things as attitudes and values. Human behavior is shaped by psychological traits, as personality types vary from person to person, producing different actions and behavior.

Human behavior encompasses a vast array of domains that span the entirety of human experience. Social behavior involves interactions between individuals and groups, while cultural behavior reflects the diverse patterns, values, and practices that vary across societies and historical periods. Moral behavior encompasses ethical decision-making and value-based conduct, contrasted with antisocial behavior that violates social norms and legal standards. Cognitive behavior involves mental processes of learning, memory, and decision-making, interconnected with psychological behavior that includes emotional regulation, mental health, and individual differences in personality and temperament.

In psychoanalysis and other psychological theories, the unconscious mind (or the unconscious) is the part of the psyche that is not available to introspection. Although these processes exist beneath the surface of conscious awareness, they are thought to exert an effect on conscious thought processes and behavior. The term was coined by the 18th-century German Romantic philosopher Friedrich Schelling and later introduced into English by the poet and essayist Samuel Taylor Coleridge.

The emergence of the concept of the unconscious in psychology and general culture was mainly due to the work of Austrian neurologist and psychoanalyst Sigmund Freud. In psychoanalytic theory, the unconscious mind consists of ideas and drives that have been subject to the mechanism of repression: anxiety-producing impulses in childhood are barred from consciousness, but do not cease to exist, and exert a constant pressure in the direction of consciousness. However, the content of the unconscious is only knowable to consciousness through its representation in a disguised or distorted form, by way of dreams and neurotic symptoms, as well as in slips of the tongue and jokes. The psychoanalyst seeks to interpret these conscious manifestations in order to understand the nature of the repressed.

Potential generally refers to a currently unrealized ability. The term is used in a wide variety of fields, from physics to the social sciences to indicate things that are in a state where they are able to change in ways ranging from the simple release of energy by objects to the realization of abilities in people.

The philosopher Aristotle incorporated this concept into his theory of potentiality and actuality (in Greek, dynamis and energeia), translated into Latin as potentia and actualitas (earlier also possibilitas and efficacia). a pair of closely connected principles which he used to analyze motion, causality, ethics, and physiology in his Physics, Metaphysics, Nicomachean Ethics, and De Anima, which is about the human psyche. That which is potential can theoretically be made actual by taking the right action; for example, a boulder on the edge of a cliff has potential to fall that could be actualized by pushing it over the edge.

Pneuma (Ancient Greek: πνεῦμα, romanized: pneûma) is an ancient Greek word for "breath", and in a religious context for "spirit". It has various technical meanings for medical writers and philosophers of classical antiquity, particularly in regard to physiology, and is also used in Greek translations of ruach רוח in the Hebrew Bible, and in the Greek New Testament.

In classical philosophy, it is distinguishable from psyche (Ancient Greek: ψυχή, romanized: psūkhḗ), which originally meant "breath of life", but is regularly translated as "spirit" or most often "soul".

Nafs (نَفْس) is an Arabic word occurring in the Quran, literally meaning "self", and has been translated as "psyche", "ego" or "soul". The term is cognate with the Hebrew word nephesh, נֶפֶשׁ. In the Quran, the word nafs is used in both the individualistic (verse 2:48) and collective sense (verse 4:1), indicating that although humanity is united in possessing the positive qualities of a nafs, they are individually responsible for exercising the agencies of the "free will" that it provides them.

Much of the popular literature on nafs, however, is focused on the Sufi conceptions of the term located within the sadr (the chest). According to the Sufi philosophies, the nafs in its unrefined state is "the ego", which they consider to be the lowest dimension of a person's inward existence—his animal and satanic nature. Nafs is an important concept in the Islamic tradition, especially within Sufism and the discipline of gnosis (irfan) in Shia Islam.
