Interiorization of Technology
The process by which an artificial tool becomes so naturalized it is experienced as <em>self</em> rather than <em>other</em>—writing as thought, the car as mobility.
Interiorization is Ong's term for the absorption of a technology into consciousness so complete that the technology becomes invisible. A fully interiorized tool is not experienced as a tool. It is experienced as an extension of the self, a natural capability, the way thinking simply works. The literate person does not experience writing as a technology she is using; she experiences it as thought itself. The driver does not experience the car as a machine she operates; she experiences it as mobility. The boundary between self and tool has dissolved. This dissolution is not a metaphor—it is a measurable cognitive and phenomenological event, documented through the restructuring of neural circuits, the automation of motor patterns, and the shift from effortful to automatic processing. Ong argued that interiorization is the endpoint of every successful technology: the tool is internalized, the effort disappears, and the capability remains—experienced as nature rather than artifact. The paradox is that interiorization's success produces blindness. The more completely a technology is absorbed, the less visible its effects become.
