Tool-Being offers a new assessment of Martin Heidegger's famous tool-analysis, and with it, an audacious reappraisal of Heidegger's legacy to twenty-first-century philosophy.

Every reader of Being and Time is familiar with the opposition between readiness-to-hand (Zuhandenheit) and presence-at-hand (Vorhandenheit), but commentators usually follow Heidegger's wishes in giving this distinction a limited scope, as if it applied only to tools in a narrow sense. Graham Harman contests Heidegger's own interpretation of tool-being, arguing that the opposition between tool and broken tool is not merely a provisional stage in his philosophy, but rather its living core. The extended concept of tool-being developed here leads us not to a theory of human practical activity but to an ontology of objects themselves.

Tool-Being urges a fresh and concrete research into the secret contours of objects. Written in a lively and colorful style, it will be of great interest to anyone intrigued by Heidegger and anyone open to new trends in present-day philosophy.
