The book by Graham Harman (b. 1968), one of the key figures in the “speculative realism” movement, is an attempt at a holistic and consistent presentation of his own teaching, “object-oriented ontology.” What is the world of objects independent of human presence in the world? Why is art vital to the practice of philosophy? How do objects help us understand what is happening in the world of society and politics? What is the impact of object-oriented ontology on architecture? Finally, how does object-oriented ontology differ from other influential movements: archeology of knowledge, genealogy, deconstruction, actor-network theory and “new materialism”? The influential American philosopher tries to answer these and other questions in his popular introduction to the “metaphysics of objects.” The publishing layout is saved in PDF A4 format.
