ABSTRACT
This chapter provides a detailed look at the ideas of some of the most important panpsychist philosophers of the 1800s. Schopenhauer, Fechner, and Nietzsche are examined in depth, and commentary is provided on the work of Lotze, Clifford, Butler, Mach, Haeckel, Prince, Royce, and Peirce. The wide acceptance of panpsychism in this century makes for notable contrast with its decline in the 20th century.
