Within the depth-psychology corpus, ‘concept’ functions as a contested epistemological category rather than a settled cognitive datum. Barrett’s constructionist neuroscience provides the most systematic treatment, arguing against both the classical view — concepts as dictionary definitions with firm categorical boundaries — and naïve realist assumptions that concepts are discrete ‘things’ stored in the brain. For Barrett, a concept is a population of instances, constructed ad hoc through degeneracy and simulation, inextricably bound to language, culture, and social reality. Jung approaches the problem from a different angle: he distinguishes qualitative from quantitative concepts in the context of psychic energy, insisting that energy is a ‘higher concept of relation’ irreducible to any single drive or substance — a methodological scruple with direct consequences for his quarrel with Freudian sexualism. Bion’s contribution is genetic: concepts emerge from the abstraction of constantly conjoined emotional elements, with a word serving as the name of a hypothesis rather than a fixed referent. Snell traces the historical genesis of the general concept in Greek thought, linking it to the substantivation of adjectives and verbs and the emergence of the generic article. Across these traditions, the shared tension concerns whether concepts are derived from experience or impose structure upon it — a tension that runs from Presocratic abstraction through psychoanalytic epistemology to contemporary affective neuroscience.
A concept is not a ‘thing’ that exists in the brain, any more than ‘space’ is a physical thing that the universe expands into. ‘Concept’ and ‘space’ are ideas.
Barrett argues that reifying ‘concept’ as a discrete brain entity commits the same category error as treating ‘space’ as a physical container — both are theoretical ideas instantiated as dynamic, population-level patterns.

Your brain learned these regularities as concepts long ago, and it uses those concepts now to categorize your continually changing visual input. Without concepts, you’d experience a world of ever-fluctuating noise.
Barrett establishes concepts as the brain’s learned statistical regularities that impose perceptual stability on otherwise undifferentiated sensory flux.

Any given concept is not represented in the information flow among one single set of neurons; each concept is itself a population of instances, and these instances are represented in different patterns of neurons on each occasion. The concept is constructed in the moment, ad hoc.
Barrett defines a concept as a degenerate, ad hoc population of neurally distributed instances rather than a fixed representational structure, with implications for how emotion concepts are constructed.

What exactly is a concept? That depends on which scientists you ask, which is business as usual in science. We must expect a certain amount of controversy around a topic as fundamental as ‘how knowledge is organized and represented in the human mind.’
Barrett frames the definition of ‘concept’ as a live scientific controversy central to understanding how emotions are constructed, rejecting the classical view of necessary-and-sufficient features.

Energy includes these in a higher concept of relation, and it cannot express anything else than the relations between psychological values.
Jung insists that the concept of psychic energy is a relational concept irreducible to any qualitative specification such as libido or drive, marking his methodological distance from reductive monisms.

A qualitative concept is always the description of a thing, a substance; whereas a quantitative concept deals with relations of intensity and never with a substance or a thing.
Jung draws a fundamental epistemological distinction between qualitative and quantitative concepts, arguing that energy as a psychological concept must remain quantitative to avoid collapsing into vitalism or sexualism.

The general concept, we may conclude, absorbs characteristic features of all three types of noun — proper, concrete, and abstract — ; we may go so far as to say that rational thought, or logic, is the product of a combination of all three.
Snell traces the phylogenesis of the general concept in Greek linguistic history, showing how it synthesises proper, concrete, and abstract noun functions to become the vehicle of rational thought.

The new product which the crucible gave forth was the rational, the concept. It needs only to be added that, as regards the history of language, the noun conquered more and more territory.
Snell identifies the rational concept as the emergent product of Greek linguistic evolution, specifically the progressive nominalization that made abstract philosophical thought possible.

From the emotional experience the infant abstracts certain elements… thus a vocabulary is established. The theory I abstract is: ‘Daddy’ is the name of an hypothesis.
Bion’s genetic account holds that concepts originate as hypotheses — names for patterns of constantly conjoined emotional elements — giving concept formation a fundamentally relational and inferential character.

Emotion words hold the key to understanding how children learn emotion concepts in the absence of biological fingerprints and in the presence of tremendous variation.
Barrett argues that emotion words are the primary vehicle by which children acquire emotion concepts, positioning language as constitutive rather than merely expressive of conceptual content.

You need a word to teach a concept efficiently. Collective intentionality requires that everyone in a group shares a similar concept… For all practical purposes, this learning requires a word.
Barrett argues that while some concepts precede their verbal labels, the social transmission of concepts — especially emotion concepts with no perceptually fixed referent — depends constitutively on shared words.

German has three distinct ‘Angers’ and Mandarin has five. If you were to learn any of these languages, you’d need to acquire these new emotion concepts to construct perceptions and experiences with them.
Barrett uses cross-linguistic variation in emotion vocabulary to demonstrate that emotion concepts are culturally constructed rather than biologically universal, with direct consequences for affective experience.

The sounds of the words introduce statistical regularity that speeds concept learning… words invite an infant to form a concept, but only when adults speak with intent to communicate.
Barrett reviews developmental evidence showing that linguistic input from communicating adults accelerates concept formation in infants, establishing the social-communicative matrix as essential to conceptual development.

Your brain combined bits and pieces of knowledge of previous apples you’ve seen and tasted, and changed the firing of neurons in your sensory and motor regions to construct a mental instance of the concept ‘Apple.’
Barrett illustrates simulation as the neural mechanism by which concepts are instantiated, showing that conceptual activity recruits the same sensorimotor systems as direct perception.

Concepts like ‘Excitement,’ ‘Fear,’ and ‘Exhaustion’ are tools for you to regulate other people’s body budgets, not just your own.
Barrett extends the function of emotion concepts beyond self-regulation to social influence, arguing that shared conceptual categorisation is the mechanism by which affective states are communicated and leveraged interpersonally.

Goal-based concepts are super flexible and adaptable to the situation… you’ll construct instances of the concept ‘Fish’ that best suit your fish tank.
Barrett introduces goal-based concepts as a more flexible alternative to prototype and exemplar models, emphasising that conceptual content is dynamically recruited in service of present intentions.

From these concepts I have borrowed only the concrete character of the term, not the definition of the concept.
Jung clarifies his use of ‘libido’ by distinguishing the concrete character of the term from the substantive definitions of related historical concepts such as Schopenhauer’s Will or Bergson’s élan vital.

SECTION V THE CONCEPT OF DISEASE Dementia praecox comprises the majority of psychoses heretofore designated as functional. This very idea implies a special systematic conception of mental diseases.
Bleuler invokes the concept of disease as a classificatory and nosological problem, noting that any diagnosis of dementia praecox presupposes a theoretical conception of what mental disease is.

A sensory representation is thought to have a minimal amount of categorization; that is, input is registered in the brain with relatively little ‘top-down’ processing.
Siegel distinguishes raw sensory registration from conceptually mediated perception, implicitly supporting a hierarchical model in which concepts function as top-down categorising structures applied to incoming sensory data.
