Marking the Seam - What a Sentence Is Doing

Accounts of consciousness routinely borrow vocabulary from physics — field, phase, coherence, superposition — and the borrowing carries an unpaid debt: a term imported from a discipline arrives with that discipline's warrant attached. This essay defends a compositional practice I call the seam, the requirement that a work mark, in its sentences, whether a given claim is formal, empirical, or interpretive. Each register has its own condition of failure, and a claim that migrates between them unmarked acquires an immunity that resembles strength and is not. Drawing on Levine's relocation of the mind–body problem from metaphysics to explanation, and on Atmanspacher's separation of quantum formalism from quantum metaphysics, I argue that the seam is a disclosure practice rather than a demarcation criterion, and that it therefore survives Laudan's objection to demarcation: it makes no ruling on what counts as science, but supplies the precondition for assessing the credentials Laudan says we should assess. Because the seam exists only insofar as it is realized in prose, I locate its mechanism in the metadiscourse literature. I close with its cost — the seam renders underdeveloped ideas legible as underdeveloped, which is the practice working rather than failing.
