This text explores the fundamental distinction between human adaptation to adverse external circumstances and the genuine sense of being "at home." The author argues that merely adjusting to harsh conditions does not equate to domestication or internal acceptance; circumstances remain external factors that either permit or exclude existence. The concept of "osvětí" (umwelt) is introduced as an environment adopted for survival, yet the author identifies a profound gap between this functional adaptation and the creation of a true home. This philosophical reflection extends to a cosmological scale, questioning the very nature of life within the universe. It ponders whether life is merely an "exotic" intruder—an outsider spreading through spores and surviving in rare, hospitable niches—or if life is fundamentally "at home" in the cosmos. Ultimately, the document examines whether the potential for life is an essential, intrinsic property of the universe rather than a secondary, accidental phenomenon occurring in isolation.
