The question of being? A senseless querying of what must be an absolute presupposition. If treated as a question there is no way of answering it ... Heidegger has displays of surprising ignorance, unscrupulous distortion and what can fairly be described as charlatanism.
British analytic philosopher A.J. Ayer in 1982
Heidegger's writings contain the last despairing glimmer of German romantic philosophy. His major work Being and Time is formidably difficult - unless it is utter nonsense, in which case it is laughably easy. I am not sure how to judge it, and have read no commentator who even begins to make sense of it.
British conservative philosopher Roger Scruton in 1992
