Some marginal markings and notes, mostly in pencil, otherwise a fine copy. (8), 174, (1) pp. First edition of one of the most important and influential works of the later Heidegger, which presents us with his unravelling of science, technology, Metaphysics and thinking (Denken), "What is Called Thinking?"The work contains the lectures given on this subject in the Winter of 1951-52 and the Summer of 1952.Heidegger here poses the question of what it is, that which is called thinking. A further question asked is, weather there is a "thinking", which has its purpose in itself and an aim that is not without itself, i.e. a thinking, which is self-sufficient and fulfilled through itself. We are thus confronted with two ways of thinking; one, which allows us to see the thing or nature in itself; the other, which challenges nature and thereby makes it appear to us in a certain way, which we can deduct and calculate our way to, -in this way nature remains a system of information, within which we will never experience what it might really be.
