The Essence

Hiedgger's essay asks us to ponder the essence of technology in a sense that is not only what technology is or how it works for us, but how it (as technology) remians through time as what it is. With this weeks question of how theory and history interact, you can gain some sort of answer from Heidegger.
It seems, to me, that through the history of our technology ("technology" for this post defined by McLuhan as extension of the human form and consciousness) it has been the goal of humans to expand our reach as individuals at a globular level... since the beginning of invention the reason for technology resides within the human drive to experience/know its surroundings.
It is only through history that human ( as a consciousness) can look back on what it has made and truly investigate the instinctual nature of these devices. Heidegger defines technology as ordering the revealing of something that was before contained. In terms of the natural, he uses a budding flower as an example, but had he been able to experience the internet as it is today I believe he may have made some deeper.
In a sense, the knowledge of our history is contained in the planet, and for human's to recognize and harness the ability of the planet's resources to collect, transmit and store that knowledge within a device like a computer, or the internet (which has no physical basis in "what is real") is truly a collaberation of human history and applying theory (be it the theory of knowledge or thought, or scientific theory) to the various resources available, and what we have created in time from them.
Technology pervades time in the sense that all form of creation is the application of theory. The essence of technology, to me, is human endeavor.
