Definition: Vernadsky, a Russian geochemist, defined the noosphere as the sphere of human reason, where scientific thought and rational activity transform the biosphere and geosphere. He saw consciousness as the driving force behind humanity’s ability to manipulate natural processes (e.g., agriculture, nuclear energy), creating a new geological epoch dominated by human intelligence.
Consciousness Connection: For Vernadsky, consciousness is primarily individual and collective human cognition, expressed through scientific discovery, technology, and resource management. The noosphere emerges as these conscious activities become globally coordinated, amplifying humanity’s impact on Earth. It is less about metaphysical consciousness and more about practical, rational thought shaping the planet.
Example: The development of the internet, enabling global knowledge-sharing, reflects the noosphere as a product of collective rational consciousness.
