The history of philosophy is a history of moral circle expansion. This history correlates with a history of expansionism about consciousness. Recently, expansionism about consciousness has exploded: to invertebrates, to plants, to logic gates, and to fundamental entities. The last of these expansions stems from a surge of interest in panpsychism. In an exploratory spirit, this paper considers some largely uncharted territory: the ethical implications of panpsychism. Our conclusion is that while panpsychism probably does significantly expand our moral circle, it's (...) also probably short on anything of practical significance. (shrink)
