Heidegger on Technology

This is an excellent tutorial explaining Heidegger's essay on technology, "The Question Concerning Technology".

The key word to understand the essay, as the tutorial explains it, would be "enframing" which as I understood it, means approaching the world through predefined categories rather than letting the world reveal or unconceal the truth on its own terms (which is actually the domain of art and poetry). This essay can also be seen as a critique of science itself though I think it is more valid in social sciences where methodologies and categories are more suspect and subject to constant questioning. Although it is also true that even in so-called "pure" sciences like Physics, modern advances have shown that previous categories are no longer valid or useful. The essay also makes it clear that techonological approach to the world precedes science and reverses the idea of technology as applied science. Somewhat related, an essay on environmental ethics which uses Heideggerian terminologies. I haven't read it in full but it looks interesting.
