In 1922, Teilhard wrote in an essay with the title 'Hominization': "And this amounts to imagining, in one way or another, above the animal biosphere a human sphere, a sphere of reflection, of conscious invention, of conscious souls (the noosphere, if you will)" (1966, p. 63)It was a neologism employing the Greek word noos for "mind". (Teilhard de Chardin, "Hominization" (1923), "The Vision of the Past" pages 71, 230, 261)
