Ernst Mach (1838-1916) was an Austrian physicist and philosopher of science. In this 1906 English language translation of his work, Space and Geometry, Mach drew distinctions between physiological (or psychological) and geometric spaces. In a sense, Mach was joining in the controversies of his time involving conceptions of knowable space.
On these pages Mach discussed conceptions of space arrived at through “sensuous imagination.”
