A syllogism (Greek: ÏÏÎ»Î»Î¿Î³Î¹ÏÎ¼ÏÏ â syllogismos â  conclusion ,  inference ) is a kind of logical argument that applies deductive reasoning to arrive at a conclusion based on two or more propositions that are asserted or assumed to be true. Minor premise: These books are from that store. 2  The major premise of a syllogism makes a general statement that the writer believes to be true. 3  The minor premise presents a specific example of the belief that is stated in the major premise. 4  If the reasoning is sound, the conclusion should follow from the two premises.
