Predicate Logic Although Propositional Logic is complete... It is still inadequate. All men are mortal. Socrates is a man. Socrates is mortal. VALID

Predicate Logic VALID All A are B n is A n is B Although Propositional Logic is complete... It is still inadequate. All men are mortal. Socrates is a man. Socrates is mortal.

Predicate Logic VALID To capture what makes this form valid we need to notate the subject and predicate of a proposition. All A are B n is A n is B Although Propositional Logic is complete... It is still inadequate. All men are mortal. Socrates is a man. Socrates is mortal.
