The noosphere can be seen as the "sphere of human thought" being derived from the Greek νους ("nous") meaning "mind" in the style of "atmosphere" and "biosphere". Just as the biosphere is composed of all the organisms on Earth and their interactions, the noosphere is composed of all the interacting minds on Earth. The word is also sometimes used to refer to a transhuman consciousness emerging from these interactions. This is the view proposed by the theologist Pierre Teilhard de Chardin, who added that the noosphere is evolving towards an ever greater integration, culminating in the Omega Point—which he saw as the ultimate goal of history.
