Tautologies are important in logic because they reflect principles of logical necessity. Symbolic Representation One common tautology is: p ∨ ¬p This
What is the Middle Term in Logic? In a categorical syllogism, the middle term is the term that appears in both premises but not in the conclusion. Its purpose is to link the subject and predicate of the conclusion logically. Structure Consider the syllogism: Premise 1: All mammals are warm-blooded. (Middle term: mammals) Premise 2:

It is symbolized by the “∧” sign and is commonly known as the logical AND. Structure If p and q are two propositions, then their conjunction is written as:
What is Deductive Reasoning? Deductive reasoning is a logical process in which a specific conclusion is drawn from a set of general premises. If the premises are true and the reasoning is valid, the conclusion must also be true. This method is commonly used in mathematics, science, and philosophy. Structure Deductive reasoning often follows the

What is Existential Instantiation? Existential instantiation is a logical rule used in predicate logic. It allows us to take a general existential statement and infer a specific instance of it. This is helpful in logical proofs where we need to work with a particular example from a general statement. Definition From the statement “∃x P(x)”
