قلنا لأن الكلام في الجوهر الفرد يتعلق بأمور هندسية يطول القول في حلها. ثم ليس فيه ما يدفع الإشكال فإنه يلزم أن تكون القدرة والإرادة أيضا في ذلك الجزء فإن للإنسان فعلا ولا يتصور ذلك إلا بقدرة وإرادة ولا يتصور الإرادة إلا بعلم وقدرة الكتابة في اليد والأصابع، والعلم بها ليس في اليد إذ لا يزول بقطع اليد ولا إرادتها في اليد فإنه قد يريدها بعد شلل اليد وتتعذر لا لعدم الإرادة بل لعدم القدرة.
