Hundred Schools of Thought: Peer Review, Disciplinary Silo, and the Institutionalization of Epistemic Arrest

The Spring and Autumn period and its successor Warring States era produced, across roughly four centuries of political fragmentation, an intellectual output that has not been matched in density or cross-domain synthesis by any subsequent period in the civilizational history that followed it. The Hundred Schools of Thought — 百家諸子 — competed openly, without institutional gatekeeping, without disciplinary silos, and without any mechanism for enforcing paradigmatic consensus. The Han institutionalization of Confucianism as state orthodoxy in 136 BCE ended that competition. The intellectual output of the following two millennia, in the domain of political and social philosophy, reflects the architecture of closure more faithfully than it reflects the architecture of the period it claims to continue. This paper argues that modern peer review and the disciplinary silo system constitute the Han institutionalization of the Qin conquest in epistemic form: a consolidation of institutional authority that ends open competition by replacing it with a gatekeeping mechanism whose primary function — whatever its stated purpose — is the maintenance of paradigmatic consensus within defined domains. The paper examines the mechanisms through which peer review produces this effect: paradigm enforcement, consensus bias, anonymous-review accountability deficit, and citation-cartel dynamics. It traces the parallel architecture through which disciplinary silos convert the natural organization of knowledge into hard boundaries that arrest cross-domain synthesis. It then argues that the combination produces a specific failure mode — epistemic arrest — in which knowledge accumulates rapidly within domains while synthesis across them becomes structurally impossible rather than merely difficult. The preprint revolution (arXiv, bioRxiv, PhilArchive, SSRN, Zenodo) is identified as the first structural rupture in this system since its consolidation in the early twentieth century. It is not a solution. It is the first condition for one.
