The noosphere (/ˈnoʊ.əsfɪər/; sometimes noösphere) is the sphere of human thought. The word derives from the Greek νοῦς (nous “mind”) and σφαῖρα (sphaira “sphere”), in lexical analogy to “atmosphere” and “biosphere”. It was introduced by Pierre Teilhard de Chardin in 1922 in his Cosmogenesis
Teilhard perceived a directionality in evolution along an axis of increasing Complexity/Consciousness. For Teilhard, the noosphere is the sphere of thought encircling the earth that has emerged through evolution as a consequence of this growth in complexity / consciousness. The noosphere is therefore as much part of nature as the barysphere, lithosphere, hydrosphere, atmosphere and biosphere. As a result, Teilhard sees the “social phenomenon the culmination of and not the attenuation of the biological phenomenon.” These social phenomena are part of the noosphere and include, for example, legal, educational, religious, research, industrial and technological systems. In this sense, the noosphere emerges through and is constituted by the interaction of human minds.
The noosphere thus grows in step with the organization of the human mass in relation to itself as it populates the earth. Teilhard argued the noosphere evolves towards ever greater personalisation, individuation and unification of its elements. He saw the Christian notion of love as being the principal driver of noogenesis. Evolution would culminate in the Omega Point – an apex of thought/consciousness – which he identified with the eschatological return of Christ.
Jose Arguelles, author and artist, evolved Teilhard’s thinking elaborating the concept of a noosphere a global work of art. Specifically, he envisioned a “rainbow bridge” encircling the Earth.
