 John Buridan was another logician of the 14th century holding a theory of the insolubles similar to Bradwardine’s and the modified Heytesbury solution. However, there may have been no direct influence. Like Rimini, Buridan also taught at the University of Paris, but unlike Rimini, rather unusually remained a teaching master in the Arts Faculty for his entire career, from the 1320s until at least 1358. We can trace the development of his approach to the insolubles from his early Quaestiones Elencorum, dating from the 1330s, and Treatise on Consequences, through his commentaries on Aristotle’s Posterior Analytics, Sophistical Refutations, and Metaphysics, to the various treatises of the Summulae de Dialectica, which was repeatedly revised over twenty years. His final view is described in the ninth and last treatise of the Summulae, with the independent title Sophismata, in a version from the mid-1350s (see Pironet 1993).
