لا شيء من ج ب، وكل أ ب
No C is B, and every A is B.
The minor is universal negative and the major universal affirmative. The conclusion is “No C is A.”
The minor keeps C outside B, whereas the major puts every A inside B. No C can therefore be A: otherwise it would both belong to B and be outside B, a contradiction.
