In one interview, filmmaker Margaret von Trotta compared Heidegger and Arendt and stated that the former withdrew into the solitude of lonely thinking while the latter decided to think publicly and with the people. Von Trotta's view is also Arendt's view, at least as it is seen in "Heidegger the Fox," where Heidegger is portrayed as a fox who is an expert at trapping people because he himself lives in a trap all the time.
How would Heidegger respond to von Trotta and Arendt? Heidegger would say that speaking "with the people" and "in public" might easily end up reproducing the dominant ideology through "idle talk." If one really wants to say something, then one needs to withdraw from the public and the people, as Descartes, Kant, Collingwood, and many others withdrew.
