Deductive reasoning is a logical thinking method that derives specific conclusions from general propositions. Specifically, it refers to logically deriving “individual propositions” from “universal propositions”.
For example, from the premise that “all humans die (universal proposition)”, the conclusion that “Socrates is human, so Socrates will die (individual proposition)” is derived. This is deductive reasoning.
A characteristic of deductive reasoning is its “truth-preserving” nature. If the premise is true, the conclusion is also necessarily true. However, it is difficult to gain new knowledge, as the conclusion is already contained in the premise, which poses a problem in that new knowledge cannot be obtained.
Furthermore, while deductive reasoning can be utilized as a communication tool in business scenes, care must be taken as the logic can break down if uncertain grounds or subjectivity are introduced. Thus, deductive reasoning is an important method for logical thinking and discussion.
