"Peter Trawny knows Heidegger's manuscripts from the 1930s and 1940s better than anybody. This essay offers a thoughtful and illuminating introduction to the issues they raise that will be of value to specialists as well as beginners. I highly recommend it.? Robert Bernasconi, Penn State University

?A beautifully-written text, not only a brilliant discussion of why Heidegger published the Black Notebooks, but also a deeper and more lasting philosophical discussion about Heidegger?s views on truth, ethics, tragedy and failure.? Eduardo Mendieta, Stony Brook University
