As an academic, Paul Mattick has worked in three fields: philosophy of language/linguistics; aesthetics; and the critique of political economy. His book Art in Its Time explores the history of art theory as a guide to the history of art as a social institution. His most recent publication, Business as Usual, is a study of the capitalist economy in the light of its most recent difficulties. He was editor of The International Journal of Political Economy for 13 years, and is currently finishing a book, Theory as Critique, on Marx's Capital.
Outside of academia, Mattick has written art criticism for Art in America, Arts, and Artforum; he is the author or coauthor of a number of museum and gallery catalogue essays; and was a regular book reviewer for The Nation and The New York Times. He is currently the politics editor for The Brooklyn Rail.
