No, it is not a syllogism. A syllogism has THREE terms. Your example has two. A syllogism is in the format of Major Premise Minor Premise Conclusion
All M is P S is M Therefore S is P -------------------------------------------------- Your example is in the form of Propositional Logic, or IF-THEN logic. If p then q p Therefore q Or, If A then C A Therefore C This is called the modus ponens. So, it would be IF A is true, then C is a matter of course [I surmise that] A is true Therefore, C is a matter of course. Edwina ----- Original Message ----- From: Jerry Rhee To: Peirce-L Sent: Saturday, April 23, 2016 7:12 PM Subject: [PEIRCE-L] Is CP 5.189 a syllogism? Hi everyone, I'm trying to figure something out. I've convinced myself but am not completely sure, so would like to work this out with the community. I haven't read Aristotle. Are there steadfast rules to syllogism one must never ever break or is there an essence? What is the intention of syllogism? Would you say the following is a syllogism? Why or why not? The surprising fact, C, is observed. But if A were true, C would be a matter of course. Hence, there is reason to suspect that A is true.
