What does cosmism mean?
Cosmism is a philosophical movement that emerged in late-nineteenth-century Russia, built on the conviction that humanity is not confined to Earth but destined to evolve, spread through, and ultimately transform the cosmos. Its early exponents — notably Nikolai Fyodorov, who imagined resurrecting past generations so they might join the cosmic venture, and Konstantin Tsiolkovsky, the schoolteacher whose rocketry equations made him a founding figure of astronautics — blended Orthodox spirituality, utopian politics, and scientific speculation. Cosmism later influenced Soviet space culture and continues to resonate in modern debates about transhumanism, space settlement, and technology-driven futures. Today the word most often appears in scholarly and journalistic contexts discussing these ideas, frequently as "Russian cosmism." Its tone is ambitious and idealistic, sometimes invoked ironically for Silicon Valley projects like Mars colonization.
nounA philosophical and cultural movement, originating in 19th-century Russia, which holds that humanity's destiny is to explore, inhabit, and ultimately transform the cosmos. It also denotes more generally any worldview that regards human evolution as inseparable from the conquest of space.
- A late-19th-century Russian philosophical and cultural movement holding that humanity must actively pursue its evolution, mastery of nature, and expansion into the cosmos — associated with figures such as Nikolai Fyodorov, Konstantin Tsiolkovsky, and Vladimir Vernadsky.
- By extension, any modern worldview or ideology that frames humanity's future in terms of space exploration, technological transcendence, and the colonization of other worlds.
"Russian thinkers such as Nikolai Fyodorov and Konstantin Tsiolkovsky laid the intellectual foundations of cosmism long before the first rockets flew."
"The Soviet space program owed more to cosmism than to pure engineering ambition; Tsiolkovsky saw rocketry as a step toward humanity's cosmic destiny."
"Silicon Valley's enthusiasm for Mars settlement has led some critics to call it a secular revival of nineteenth-century cosmism."
Rarely pluralized; the plural may appear when contrasting different varieties or interpretations of cosmism.
"Historians distinguish several distinct cosmisms, from Fyodorov's religious vision to Tsiolkovsky's materialist one."
Long before SpaceX, a Russian mystic argued we must resurrect all our dead ancestors so they could colonize the stars together — that's cosmism.

Etymology of cosmism
Cosmism derives from the Greek noun kosmos, meaning "order," "world," or "universe," combined with the English suffix -ism denoting a doctrine or movement. The term arose in the second half of the nineteenth century within Russian intellectual circles to describe the new current of thought linking humanity's fate to the wider universe. It shares its Greek root with words such as cosmos, cosmic, and cosmology, and its coinage parallels other -ism formations of the era that named emerging worldviews.

How cosmism is actually used
Cosmism is a relatively specialized term found chiefly in academic writing on intellectual history, science fiction studies, and contemporary discussions of transhumanism and spaceflight. When used unqualified it most often refers specifically to the Russian tradition, so writers usually say "Russian cosmism" when that is what they mean. It carries connotations of utopian optimism and grand historical ambition, sometimes tinged with irony when applied to modern tech-industry ventures.
