"If the technical product does not carry the principle of movement within itself but draws from another--often allowing for the judgement that such and such a product is the means of which another product is the end--nevertheless, insofar as it effects a passage from a concealed state to a nonconcealed state, one of disclosure, this bringing-forth that is particular to technics constitutes a mode of truth. This means that the final cause is not the efficient operator but being as growth and unfolding: phusis and being are synonyms, the unconcealing of phusis is the truth of being as growth and bringing-forth (poeisis). Tekhne qua poiesis is thus submitted to the final cause that phusis, working through the efficient cause, constitutes, without the efficient cause being in any way confused with the final cause."
--Bernard Stiegler, Technics and Time vol. 1.
The scary thing is, I think I might understand this stuff.
