Within the depth-psychology corpus, 'abstract' and 'abstraction' occupy a tensioned conceptual space between cognitive necessity and psychological danger. Jung's foundational definition in Psychological Types treats abstraction as the mental operation of singling out a content from its unique contextual web — a form of differentiation that liberates meaning from the irrelevant, yet simultaneously severs that meaning from lived particularity. This Jungian axis sets the dominant register: abstraction is a tool of consciousness, but one that must be measured against what it costs in concrete reality. McGilchrist extends this critique neurologically and linguistically, arguing that the grammatical capacity for abstract nouns — absent in old Japanese, generated by the Greek definite article — enacts a cultural and cognitive 'thing-ness' with profound consequences for how Western minds apprehend the world. James, writing from the pragmatist-phenomenological tradition, advances a countervailing appreciation: abstractions are 'beings as real' as sensory objects, the very medium through which mind grasps the world at all. Grof contributes a phenomenological dimension by documenting abstract geometric and architectural visions as the first, most accessible layer of LSD-induced experience, implying a tiered depth-model in which pure abstraction is comparatively superficial relative to biographical or transpersonal content. Flores, drawing on Deweyan pragmatism, warns against the confusion of abstract theory with concrete reality in clinical contexts. Together, these voices construct a field in which abstraction is simultaneously indispensable to cognition, suspect as a retreat from embodied life, and diagnostic of a distinctly Western mode of consciousness.
Abstraction, therefore, is a form of mental activity that frees this content from its association with the irrelevant elements by distinguishing it from them or, in other words, differentiating it.
Jung defines abstraction as the differentiating act by which a psychic content is liberated from its unique, incomparable context, establishing the term's technical meaning within analytical psychology.

This absolute determinability of our mind by abstractions is one of the cardinal facts in our human constitution. Polarizing and magnetizing us as they do, we turn towards them and from them, we seek them, hold them, hate them, bless them, just as if they were so many concrete beings.
James argues that abstract objects command the same affective force as concrete realities, making the mind's susceptibility to abstraction a foundational fact of human psychology.

Japanese has far fewer abstract nouns than does English, and to a surprising degree… the Japanese have nothing that corresponds to the Platonic Idea, and in fact no true abstractions in general.
McGilchrist uses cross-linguistic evidence to argue that the capacity for abstraction is a grammatically and culturally conditioned feature of Western consciousness, not a universal cognitive given.

Thing-ness could even be seen as beginning in something as remote as a grammatical shift… It is an accident, or rather a characteristic, of Greek grammar that gave us the definite article. This has the potential to turn adjectives into nouns.
McGilchrist traces the genesis of mental abstraction to a specific grammatical affordance in Greek, linking linguistic structure to the reification of experience as abstract 'things'.

In the first few LSD sessions… there is usually a preponderance of abstract experiences of various kinds. With the eyes closed, most LSD subjects have incredibly colorful and dynamic visions of geometric designs, architectural forms, kaleidoscopic displays.
Grof positions abstract visual experience as the most accessible, relatively superficial stratum of psychedelic phenomenology, implying a depth-model in which pure abstraction precedes deeper psychological content.

there is usually a preponderance of abstract experiences of various kinds… incredibly colorful and dynamic visions of geometric designs, architectural forms, kaleidoscopic displays, magic fountains, or fantastic fireworks.
Corroborating his earlier account, Grof consistently identifies abstract geometric and architectural imagery as the characteristic inaugural layer of expanded-state phenomenology.

Abstraction consists then in detaching oneself from this 'contextual' richness, which, for the person speaking, is an essential richness.
Benveniste frames abstraction in the acquisition of written language as a developmental violence — a necessary detachment from the living situational richness that motivates speech.

The generic Form must be conceived, not as a bare abstraction obtained by leaving out all the specific differences determining the subordinate species, but as a whole, richer in content than any of the parts it contains and embraces.
The Platonic tradition, as mediated here, critiques reductive abstraction, insisting that the Form is a content-rich whole that exceeds, rather than diminishes, its instantiations.

Dewey felt that too many theorists retreat from the world of chance into a safe world of abstract thought… these abstractions frequently fail to materialize.
Flores, drawing on Dewey, warns that clinicians working with addicted populations fall into a characteristic error of sheltering in abstract theory at the cost of concrete therapeutic engagement.

One can only attempt to decide this question if one can differentiate in individual cases between a concrete and an abstract concept.
In his early experimental work, Jung flags the concrete/abstract distinction as a diagnostic crux in association research, though without yet developing the full theoretical framework of his later typology.

like the mind, the apeiron is an abstract imperceptible entity exercising unifying control over the concrete multiplicity of which it in a sense consists.
Seaford notes that the first Greek philosophical abstractions — Anaximander's apeiron — were modeled partly on the structure of money and mind as unifying, imperceptible controllers of concrete multiplicity.
