My stance on Heidegger is in line with Paul Celan's one - I appreciate the level of thinking (its hard not to), but have serious issues with his **** sympathies, which he never renounced, as far as I know.
("The other N-word" doesn't exist here.) It isn't entirely clear; at one point H was drafted into a work camp. There are also issues with his relations with students. That aside, his original thinking was, or could have been if more accessible, a corrective to 2,000+ years of European philosophy, which reduced reality to "physical objects" and "other." H came along and explained that we don't live that way. When perception enters in, things aren't just things. I think his work has implications for visual presentations.
