Introduction

What is a Syllogism? A syllogism is a deductive argument relating two premises and a conclusion, all of which are quantified propositions, i.e. propositions joining concepts by using words such as ‘some’ and ‘all’. In simple terms, Syllogism is a deductive argument that is primarily composed of 3 propositions. One of the propositions is used as the conclusion of the syllogism and the other two propositions are used as the premises of the syllogism. Deductive Logic is used to derive conclusions from premises where the truth of the conclusion must always be contained in the truth of the premises.
