Book excerpt: Heidegger's major be-ing-historical treatise, Beiträge zur Philosophie (Vom Ereignis), opens up the full depth and final range of his experience of thinking. It has a substantial bearing on the understanding, assessment, and appropriation of his lifework, not just on the interpretation of his later writings. The exploration of this unique work raises basic questions about the nature and task of thinking, not simply about Heidegger’s claims and insights. "Thinking and Be-ing in Heidegger's Beiträge zur Philosophie (Vom Ereignis)” by George Kovacs is a questioning confrontation with the main issues at stake in Heidegger’s thought. In contending with Heidegger's venture, George Kovacs clearly demonstrates that the re-thinking of the entire question of Being, of the ubiquitous and indispensable "is," is at the same time a re-thinking of the way of thinking, of thinking itself; it is a rediscovery of and an experience with language. This comprehensive, focused research contributes to the reawakening of the sense of wonder and curiosity about Being, beings, and human being's dwelling in the world, the primordial concern of Heidegger’s thought.
