 Aristotle, in the sixth book of the Physics, develops several arguments against the idea that continua are composed of atoms or indivisibles. The majority of medieval philosophers accepted Aristotle’s position, but by the end of the thirteenth century there developed a minority opinion that supported indivisibilism. The most famous proponents of indivisibilism were Robert Grosseteste (d. 1253), Henry Harclay (d. 1317), Walter Chatton (d. 1343), Gerard Odon (d. 1349), William Crathorn (fl. 1330s) and Nicholas Bonet (d. 1360). The divisibilists/indivisibilist debate in the fourteenth century was concerned with the philosophical status of space and time. Spacial-temporal reality, according to the traditional Aristotelian view, was infinitely divisible. Thus, authors like Thomas Bradwardine and Adam Wodeham follow Aristotle and Averroes in defending the view that the continuum is composed of divisible parts without end, and not of atoms. This view (divisibilism) is the one defended by Adam Wodeham in his magisterial Tractatus de indivisibilibus.
