Aristotle - The Organon - index for ANALYTICA PRIORIA Book 1 Part 11

The third figure with one necessary premiss

  
Paragraph 1 In the last figure when the terms are related universally to the middle, and both premisses are affirmative, if one of the two is necessary, then the conclusion will be necessary.
Paragraph 2 Again let AC be negative, BC affirmative, and let the negative premiss be necessary.
Paragraph 3 If, then, the premisses are universal, we have stated when the conclusion will be necessary.
Paragraph 4 But if one premiss is affirmative, the other negative, whenever the universal is both negative and necessary the conclusion also will be necessary.
