Deductive Reasoning

Save

Deductive reasoning is a form of logical reasoning that involves making a conclusion based on a set of premises. The premises are assumed to be true, and the conclusion must follow logically from the premises. Deductive reasoning is often used in mathematics, philosophy, and law.

Understanding Deductive Reasoning

Deductive reasoning is based on the principle of syllogism, which is a logical argument that consists of three parts: a major premise, a minor premise, and a conclusion. The major premise makes a general statement about a class of things. The minor premise makes a specific statement about a member of that class. The conclusion draws a specific conclusion about the member of the class based on the two premises.

Validity and Soundness

A deductive argument is valid if the conclusion follows logically from the premises. A deductive argument is sound if the premises are true and the conclusion follows logically from the premises. It is important to note that a deductive argument can be valid even if the premises are false. However, a deductive argument is only sound if both the premises and the conclusion are true.

Uses of Deductive Reasoning

Deductive reasoning is used in a wide variety of fields, including:
