Cleaning my bookshelf (and eliminating some items), I found a book the title of which ran: "How to read Heidegger" --- My reply: In no way! Do not do that. --- I did it, and I wrote long ago that I had not found in Heidegger anything which seemed to me (1) understandable, (2) true, (3) relevant and (4) new at the same time. --- Why is Heidegger considered a great philosopher? His exotic language does have a poetic dimension, but it looks empty at the level of content.
