 With respect to so-called ‘physical sophismata,’ special attention should be paid to certain fourteenth century English authors known as the “Oxford Calculators”, e.g., Richard Kilvington, William Heytesbury, Thomas Bradwardine, Richard and Roger Swineshead. These philosophers developed a distinctively “English-style” of sophismata. Based on the theological doctrine of the absolute power of God, the distinction between what is physically possible and what is logically possible (where non-contradiction is the only limit) allowed these authors to devise imaginary thought experiments. For example, suppose that A is a distance to be traversed which Socrates cannot traverse, and that his power is increased until Socrates can traverse distance A completely, and that Socrates’ power is not increased further: Is the sophisma ‘Socrates will begin to be able to traverse distance A’ true or false? (Richard Kilvington, Sophismata, sophisma 27, in Kretzmann 1990, p.60). Thought experiments such as these led these authors to develop, among other things, a theorem for uniformly accelerated motion (e.g., Thomas Bradwardine’s Mean Speed Theorem).
