This is the first time that a seminal collection of fourteen essays by Martin Heidegger (originally published in German under the title Wegmarken) has appeared in English in its complete form. It includes new or first-time translations of seven essays, and thoroughly revised, updated versions of the other seven. Amongst the new translations are such key essays as 'On the Essence of Ground', 'Hegel and the Greeks' and 'On the Question of Being'. Spanning a period from 1919–61, these essays have become established points of reference for all those with a serious interest in Heidegger. Now collected for the first time in translations by an experienced Heidegger translator and scholar, they will prove an essential resource for all students of Heidegger.
