 In response to the classical divisibilist position supported by Aristotle, the indivisibilists held that there were “indivisibles” which constituted the composition of temporal and spatial continua, e.g., temporal instants and lines respectively. Such “indivisibles”, in the early 14th century, were understood to be an extended and simple ontological unit, but not physical atoms per se. It is helpful here to consider briefly an indivisibilist account, before turning to the divisibilism of Wodeham.
