Abstract
In this lucid and insightful study, Stephen Makin investigates a form of argument widespread in ancient Greek philosophy, where the absence of a reason for one alternative to be the case rather than another is used to establish substantive conclusions—where the alternatives are “indifferent”. Examples abound: Anaximander engages in such reasoning to show that the Earth does not move; Zeno of Elea to show that what is cannot be divided; Democritus to argue for finite divisibility, on the one hand, and the infinite variety of atoms and worlds, on the other; not to mention the extensive use of such arguments in ancient skepticism.
