This volume investigates the intersection of phenomenology and posthumanism by rethinking the human and nonhuman specifically with regard to boredom, isolation, loneliness, and solitude.  By closely examining these concepts from phenomenological, philosophical, and literary perspectives, this diverse collection of essays offers insights into the human and nonhuman in the absence of the Other and within the postapocalyptic. Topics of interest include modalities of presence and absence with regard to body, time, beast, and things; the phenomenology of corporeity; ontopoiesis and the sublime; alienation, absurdity, and phenomenology of existence; memory, posthistoricity, posthuman nihilism, and posthumanity; speculative cosmology, cosmic holism, and consciousness; ecophenomenology; and the philosophy of the aesthetic.  These essays parse and probe distinct aspects of the posthuman condition and what it means to exist in a posthuman world, thereby furthering the vast,rich scope of phenomenological research and study.  This text appeals to students and researchers working in these topics and fields.
