In this book, the founder of object-oriented ontology develops his view that aesthetics is the central discipline of philosophy. Whereas science must attempt to grasp an object in terms of its observable qualities, philosophy and art cannot proceed in this way because they don't have direct access to their objects. Hence philosophy shares the same fate as art in being compelled to communicate indirectly, allusively, or elliptically, rather than in the clear propositional terms that are often taken - wrongly - to be the sole stuff of genuine philosophy. Conceiving of philosophy and art in this way allows us to reread key debates in aesthetic theory and to view art history in a different way. The formalist criticism of Greenberg and Fried is rejected for its refusal to embrace the innate theatricality and deep multiplicity of every artwork.
