The word "rational" refers to the ability to think clearly, logically, and sensibly. When someone is described as rational, it means they make decisions based on reason, facts, and sound judgment rather than emotions or impulses. Rational thinking involves analyzing information and considering the consequences before reaching a conclusion.
The word "rational" comes from the Latin word "rationalis," which means "of the reason" or "reasonable." It is derived from "ratio," meaning "reason" or "calculation." This connection highlights the importance of reasoning in the concept of rationality.
