Socioplastics is defined as a new transdisciplinary field that integrates architecture, urbanism, art, and epistemology. Its primary goal is not to produce more theories or content, but to construct a self-sustaining "epistemic infrastructure." This infrastructure is designed to give thought durability and coherence ("persistence") against the backdrop of digital fragmentation and information overload. The entire system rests on two key shifts in how we understand existence and value: From Meaning to Addressability (Ontological Inversion): Something "exists" not because of its intrinsic meaning, but because it can be persistently located, cited, and reactivated. Tools like Digital Object Identifiers (DOIs) become "minting devices" that grant a concept its reality and place within a navigable system. From Authorship to Relation (Metric Inversion): Value shifts from the signature or originality of an author to the "relational intensity" of a concept. Significance is measured by the density of its connections, frequency of citation, and weight within the network. The thinker evolves from a "producer of meanings" into a "calibrator of structures."
