Abstract

1. In the Essay, Locke’s most controversial claim, which he slipped into Book IV almost as an aside, was that matter might think (Locke1975:IV.iii.6;540-1).i Either because he was genuinely pious, which he was, or because he was clever, which he also was, he tied the denial that matter might think to the claim that God’s powers are limited, thus, attempting to disarm his critics. It did not work. Stillingfleet and others were outraged. If matter can think, then for explanatory purposes the immaterial soul might be dispensable. But throughout the eighteenth century explanatory purposes were at the top of the agenda. And what had always made the soul so handy for proving immortality - that it is non-composite, static, and inaccessible to empirical examination - is also what made it so useless for investigating human nature. By contrast, consciousness is multifaceted, dynamic, and open to empirical investigation. Early in the century a Clarke might take the high road and resist descent into the merely probable and contingent. But when it came to investigating persons, the emerging science of human nature was the only game in town. One either played it or took oneself out of the action.
