Knowledge has evolved from our cluelessness. Humanity has come a long way from an ape species learning how to survive on the Savanna. Our knowledge about the world is now quite stupendous, but there is still much to learn. The greater paradigms within the Knowledge megaparadigm are Technology, Gnosis, Philosophy, and Science. Technology and Gnosis dominated Knowledge at first, but Philosophy, and later Science, have both come to dominate this megaparadigm.
Technology is the ability to manipulate the material world through the utilization of tools.
Humanitys mental evolution would not have been possible without tools. Our ancient ancestors survived by continually fashioning more complex and specialized tools, thus beginning our mental co-evolution with them. But instead of simply reacting to the environment, we started to affect the environment for our own benefit. From the axe to the computer chip, from setting fires to digging canals, from the wheel to nuclear power, we have certainly learned how to manipulate the material world. Our technology has become quite spectacular in recent times.
