Book Review: Irrational Mechanics: Narrative Sketch of a Futurist Science & A New Religion by Giulio Prisco

This review critically engages Giulio Prisco’s Irrational Mechanics, a speculative and ambitious attempt to synthesise futurist science and metaphysical inquiry into a new religious vision. Prisco’s narrative reimagines Newtonian rationality through a quasi-theological framework that champions transcendent technologies—time travel, resurrection, faster-than-light propulsion—as the metaphysical infrastructure of a post-scientific age. The review situates Prisco’s work within the emerging discourse of space religions, drawing comparisons and contrasts with Astronism, particularly on issues of revelation, grace, morality, and institutional coherence. While praising the imaginative scope and cosmic ambition of Irrational Mechanics, the review critiques its lack of revelatory grounding, ethical orientation, and structural clarity, suggesting these as essential components for any enduring religious system. The review positions Prisco’s work as a provocative, if incomplete, contribution to the growing constellation of philosophies and theologies seeking to unite science, spirituality, and the human future in space.
