I want to know the answer to the following question:
What philosophy combined with Descartes to push quantum activity in the 20th century?
All the background I'm provided with is that "With the acquiescence of Cartesian mechanical philosophy to the "brute fact" of action at a distance, and at length, its successful reification by force fields and ever more sophisticated geometric structure, the anachronism of empty space widened until "a seething ferment" of quantum activity in the 20th century filled the vacuum with a virtual pleroma.". Is that enough to answer the question?
Answer: yes
