Mach and Panqualityism

The chapter discusses the rejuvenation of an interest in Mach in the recent metaphysics and philosophy of mind. In the early twentieth century, Mach had been interpreted as a phenomenalist, but phenomenalism fell out of favor in the 1950s. In the later decades, he received praise for his naturalism, but his contributions to metaphysics or philosophy of mind were regarded as misbegotten or irrelevant. With the search for a monistic alternative to both materialism and dualism in the recent philosophy of consciousness, however, Mach attracts a fresh attention. For example, the contemporary philosopher Sam Coleman develops a version of a monistic metaphysic called “panqualityism,” which resembles Mach’s view to a large extent. Like most contemporary monists, however, Coleman works much more closely from Russell’s The Analysis of Matter, than Mach’s The Analysis of Sensations. The chapter details the circumstances that have led to the recent rise of monism; the varieties of Russellian monism; Coleman’s panqualityism; and the similarities and differerences between panqualityism and Machian monism.
