LessonsSemantic Fallacies: Defects of Matter, Form, and PredicationQuiz

الجالس في السفينة متحرك، وكل متحرك لا يثبت في موضع واحد
A person seated in a ship is moving, and whatever moves does not remain in one place.

The first statement attributes motion to the passenger through the ship and a relevant frame of reference. The second can take “moving” in another sense, as motion belonging to the subject in the intended respect.

Proper analysis asks relative to what reference point motion is asserted, and whether the motion is intrinsic to the person or attributed through the ship. The text’s example warns against merging these respects.
