The concept comes from structuration theory, where Giddens distinguished three levels of consciousness: discursive consciousness (what actors can articulate), practical consciousness (what they know how to do without articulation), and the unconscious. Practical consciousness is the largest and most consequential layer for social action — most of what people do, they do on the basis of practical knowledge they could not fully explain.
The concept draws on the phenomenological tradition, particularly Merleau-Ponty's work on embodied perception and Michael Polanyi's tacit knowledge. What all three frameworks share is the insight that the most important kinds of human knowing are not propositional but practical — embedded in the body's trained capacities rather than in explicit beliefs that could be written down.
AI disrupts practical consciousness in a specific way. The engineer who directs an AI tool to generate code does not develop the same embodied relationship to the code that the engineer who wrote it by hand developed. The outputs may be functionally equivalent, but the experiential process — the debugging, the failure, the gradual accumulation of habits and sensibilities — is absent. Over time, the practical consciousness that traditional workflow produced as a free byproduct ceases to accumulate.
The ascending friction framework from the You On AI suggests that the response is to locate practical consciousness at a higher level — to develop embodied familiarity with architectural judgment, quality discrimination, and the direction of AI rather than with implementation. Whether this higher-level practical consciousness can substitute adequately for the lower-level practical consciousness it replaces is among the central empirical questions of the AI transition.
Giddens developed the concept in The Constitution of Society (1984) as part of structuration theory. It synthesized phenomenological insights from Merleau-Ponty, hermeneutic insights from Hans-Georg Gadamer, and sociological insights from Erving Goffman on the tacit structure of everyday interaction.
Three levels of consciousness. Discursive consciousness (articulable), practical consciousness (embodied know-how), and the unconscious form a stratified model of the acting subject.
Embodied and tacit. Practical consciousness is embodied rather than propositional and tacit rather than explicit.
Developed through practice. The only way to develop practical consciousness is to engage in the practice sufficiently for the embodied familiarity to accumulate.
AI short-circuit. AI produces outputs without requiring the practice that develops practical consciousness, creating a workflow in which embodied expertise can no longer be developed as a free byproduct.
Ascending alternative. Practical consciousness can be cultivated at higher levels — architectural judgment, quality evaluation — but this requires deliberate attention to what AI workflows no longer produce automatically.
Whether practical consciousness at higher levels is an adequate substitute for the embodied knowledge at lower levels, or whether the higher-level expertise is structurally thinner in ways that matter, is a question the AI transition is empirically resolving.
