UNIT 3 HANDOUT 4 STRUCTURE OF SYLLOGISM DR. S. DEO STRUCTURE OF SYLLOGISM Syllogism is composed of three propositions. It is a mediate inference in which the conclusion is deduced from the two given premises. The given propositions are called the premises. The proposition which follows is called the conclusion. (Basantani, K.T. Introduction to Logic, 4 th edition.) e.g. All ornaments are highly priced. All highly priced items are valuable. Hence All ornaments are valuable. Syllogism is a deductive inference hence its conclusion cannot assert more than what is asserted by the premises. If the premise is particular, the conclusion cannot be universal. The constituents propositions of the syllogism are analysed into terms. The predicate of the conclusion is called, major term, Subject of the conclusion is called, Minor tem and the term which occurs in both the premises but not in the conclusion is called Middle term. The relation between the middle term and the other two terms may be that of affirmation or negation.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
