This book brings together a series of essays that examine the relationship between uncertainty, method, and the human impulse toward premature explanatory closure. Drawing on archaeology, technology, epistemology, and systems of meaning, it analyzes how the pursuit of early certainty can function as a narrative defense that stabilizes coherence at the expense of understanding. Rather than proposing alternative histories or speculative explanations, the work develops a constraint-based approach: it identifies the conditions under which consolidated explanatory frameworks become insufficient and argues for the ethical importance of explicitly acknowledging those limits. Through discussions of material precision, discontinuity, documentary silence, and technological prostheses, the book advances not-knowing as a disciplined and responsible intellectual position. The texts that compose this volume are available as individual papers within this repository. The book-format edition does not introduce new content; instead, it offers an editorial reorganization of the material, emphasizing argumentative continuity, reading flow, and a different discursive register aimed at a less fragmented reading experience.
