>The noosphere (from the Greek *nous* (mind) and *sfaíra* (sphere)) is a philosophical concept developed and popularized by the biogeochemist Vladimir Vernadsky and philosopher and Jesuit priest Pierre Teilhard de Chardin. Vernadsky defined the noosphere as the new state of the biosphere, and described it as the planetary "sphere of reason". The noosphere represents the highest stage of biospheric development, that of humankind's rational activities. ("Noosphere", 2025).
