The Impossible Message: Embodiment, Form of Life, and the Ontological Limits of Interstellar Communication

This paper investigates whether the impossibility of communication with radically alien intelligence is technological, a problem of insufficient signal strength, encoding ingenuity, or detection sensitivity, or whether it runs deeper, into the ontological conditions under which communication, meaning, and recognition are constituted. The dominant assumption in the search for extraterrestrial intelligence holds that mathematics constitutes a universal language decodable by any sufficiently advanced cognition. This assumption rests on a series of philosophical commitments, commitments about the nature of mathematical truth, the structure of perception, the ontology of meaning, and the conditions of communication, that have been systematically challenged across the history of twentieth-century thought but whose refutation has not penetrated the scientific programmes that presuppose them. Through sustained engagement with Wittgenstein's concept of form of life, Merleau-Ponty's phenomenology of embodied perception, Lakoff and Nunez's cognitive science of mathematical cognition, Heidegger's analysis of Zuhandenheit and the constitutive role of language in the disclosure of being, Husserl's theory of perspectival manifestation, and Stiegler's concept of originary technicity, this paper traces what happens when the universalist assumption is subjected to the scrutiny these traditions provide. The investigation proceeds through the embodied foundations of mathematical thought, the dimensional architecture of cognition, the conditions under which language operates as an intranet of shared meaning, the ontological incoherence of the view from nowhere, the status of mathematics as a language game whose rules presuppose a shared form of life, and the question of whether the distinction between signal and noise is discovered in phenomena or drawn by the practices that classify them. What emerges from this investigation, and how far the consequences reach, the reader is invited to discover in the argument that follows.
