Intermediate Parts of Motion According to Ramon Llull: Some Remarks About His Medieval Background

Following Aristotle, Averroes rejects atomism and the infinite division of geometric lines. Thus, his arguments dealt with the continuity and contiguity of the non-atomic parts of motion. He vindicates the perceptual aspect of physical movement that shows itself like in-progress-path between two edge points A and B, in which there are middle parts where qualitative, local, or quantitative changes occur. Ramon Llull took the lines’ geometrical points as “motion parts.” Points are intermediate divisions that represent physical phenomena by the continuity of geometrical lines, surfaces, and figures. Also, he appeals to relational logic to spot the middle parts between A and B into the in-progress-path of motion. Those middle parts are signified by a dynamic vocabulary, called: correlative language. This contribution focuses on the conceptual environment of Llull’s assumptions, in which Averroes’ Latin readers explored the geometry and the vocabulary of motion intermediate parts.
