“Teilhard went on to argue that there have been three major phases in the evolutionary process. The first significant phase started when life was born from the development of the biosphere. The second began at the end of the Tertiary period, when humans emerged along with self-reflective thinking. And once thinking humans began communicating around the world, along came the third phase. This was Teilhard’s “thinking layer” of the biosphere, called the noosphere (from the Greek noo, for mind). Though small and scattered at first, the noosphere has continued to grow over time, particularly during the age of electronics. Teilhard described the noosphere on Earth as a crystallization: “A glow rippled outward from the first spark of conscious reflection. The point of ignition grows larger. The fire spreads in ever-widening circles, he wrote, “till finally the whole planet is covered with incandescence.”His picture of the noosphere as a thinking membrane covering the planet was almost biological – it was a globe clothing itself with a brain. Teilhard wrote that the noosphere “results from the combined action of two curvatures – the roundness of the earth and the cosmic convergence of the mind.”Marshall McLuhan was drawn to the concept of the noosphere. Teilhard’s description of this electromagnetic phenomenon became a touchstone for McLuhan’s theories of the global “electric culture.” In The Gutenberg Galaxy, McLuhan quotes Teilhard: “What, in fact, do we see happening in the modern paroxysm? It has been stated over and over again. Through the discovery yesterday of the railway, the motor car and the aeroplane, the physical influence of each man, formerly restricted to a few miles, now extends to hundreds of leagues or more. Better still: thanks to the prodigious biological event represented by the discovery of electromagnetic waves, each individual finds himself henceforth (actively and passively) simultaneously present, over land and sea, in every corner of the earth.” This simultaneous quality, McLuhan believed, “provides our lives again with a tribal base.” But this time around, the tribe comes together on a global playing field.We stand today at the beginning of Teilhard’s third phase of evolution, the moment at which the world is covered with the incandescent glow of consciousness. Teilhard characterized this as “evolution becoming conscious of itself.” The Net, that great collectivizer of minds, is the primary tool for our emergence into the third phase. “With cyberspace, we are, in effect, hard-wiring the collective consciousness,” says Barlow.”
A globe clothing itself with a brain- a n interesting proposition. The Net is collective conscious,the wiring of millions of neurons .Each individual finds himself everywhere across space and time. When I am sitting here and typing away I am not merely in my local space but am spread everywhere -a noosphere which dominates the world ,the sky and the space.
