This essay contextualizes the Dantean figure of Ulysses, as conceived by Yuri M. Lotman, and draws this key figure of modernity into a network of mutually interconnected discourses: primarily transhumanist visions of the human future in space, which nevertheless arise from the specifically modern epistemic dimension of “restlessness,” and intertwine with post-war astronautics, cyborg visions of human re-engineering, and revolutionary considerations of speculative realism. The key is Lotman’s emphasis on Ulysses as a figure of “energy of thought”; in this regard, (...) the essay shows how the original poetic “decision,” embodied by the Ulysses figure, advocates implicit cruelty in the name of the future (treated as an inevitable fate), and how this decision generates a logical and progressively unfolding series of “inhuman” images of man situated in the universe as an event of saturation of matter with merciless intelligence.
