Heidegger defines essence using Platon's theory of the idea:
Technology had always been understood as objects that bring means to an end. Heidegger seeks to define the essence of Technology. and intents to find the threat in all technologies in order to better approach and question it in the future.
Heidegger deconstructs means and end. can't they be the same?
Technology is ∴ not a cause, it is a way of revealing (althea). Bringing into reality so as to make apparent and possible the means and end.
Technology is ∴ something that is not able to be created by its own.
Modern technology is not only a way of revealing, but now also a challenging of. Not exactly althea but a new value of the act of technology itself (techne) to describe its raw power, not what it does.
Whenever humans think or exchange ideas, we rely on the recognition of others (Hegel). When everything around us is reduced to less than objects, it affects our relationship with others and ourselves.
Participating in the logic of farming means seeing the world as something to order, instead of viewing it as an autonomous ecosystem. Humans now dominate the world.
The introduction of exact sciences was not the reason why technology became modern. In fact, it is the logic of framing accelerated the technology of sciences that made modern technology possible.
Technology is ever evolving. It is its nature to always try to go beyond what technology means at the moment. If the logic of framing goes too far, we will be doomed as a species who dominates the earth.
Heidegger defines freedom as the human capacity to respect the unknown of an object, and of human beings. He argues that if objects now are extracted as to only be reserves, then humans could share the same fate eventually.
Technology's capacity to reveal (althea) is bound in part by the impossibility of ever realizing the original idea. In this disconnection we are presented with a mystery of why we even do it at all. This is part of the essence of technology.
Keeping this mystery motivates creation and it's also why there's hope; we must always be critical of technology and always question wether it is being mobilized to retain the idea of the mystery or trying to put that mystery to death.
