J. B. Schneewind's The Invention of Autonomy has been hailed as a major int
erpretation of modern moral thought. Schneewind's narrative, however, elide
s several serious interpretive issues, particularly in the transition form
late medieval to early modern thought. This results in potentially distorte
d accounts of Thomas Aquinas, Hugo Grotius, and G. W. Leibniz. Since these
thinkers play a crucial role in Schneewind's argument, uncertainty over the
ir work calls into question at least some of Schneewind's larger agenda for
the history of ethics.
