 The sixth question (fols. 175r-185r) is whether continuity and contrariety of motion (continuitas et contrarietas motuum) are present only in the categories of quantity, quality, and where. Sharpe thinks it is so, as only these three categories are properly characterized by the existence in them of distance. As a matter of fact, in these three categories are present sequences of items such that in order to move from one term to the other of the series, it is necessary to pass through intermediate terms.
