وهو أن يدخل شيئان في معنى ويفرق بين جهتي الإدخال
It brings two things under one meaning but distinguishes the respective ways in which they are included.
The figure combines two movements:
Gathering: two objects share one descriptive category or image.
Differentiation: each object shares a different aspect of that category.
Unity and difference do not cancel each other here. The same image is used twice, but the specific property motivating its application changes from one item to the other.
