Rationale vs. Reason: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Rationale refers to the underlying logic or explanation for something, while reason is a cause or a motive for an action or belief.
Key Differences
Rationale is a term that denotes a set of reasons or a logical basis for a course of action or a particular belief. It is often used in contexts where an explanation or justification is needed. Reason, on the other hand, refers to a cause or an explanation for something that happens or is done. It's more about the 'why' behind an action or a belief.

In practical usage, rationale often implies a more detailed and systematic explanation, particularly in professional or formal contexts. It is the reasoning behind a decision or theory. Reason, conversely, is more universally applied and can refer to simple, everyday explanations as well as complex justifications.

The word 'rationale' is typically used in scenarios requiring a more sophisticated level of discourse, such as academic, legal, or technical fields. It implies a comprehensive and coherent line of reasoning. 'Reason', in contrast, is a more general term that applies to motives or causes, ranging from personal feelings to logical arguments.

Another distinction lies in their connotations. Rationale often carries a sense of formality and thoroughness, suggesting a well-structured argument or explanation. Reason, while also used in logical arguments, has a broader application, including emotional or intuitive explanations.

Rationale is often used in a proactive sense, explaining the logic behind a decision before it's questioned. Reason, in contrast, can be reactive, providing an explanation or justification in response to a query.

Reason
The faculty or capacity of the human mind by which it is distinguished from the intelligence of the inferior animals; the higher as distinguished from the lower cognitive faculties, sense, imagination, and memory, and in contrast to the feelings and desires. Reason comprises conception, judgment, reasoning, and the intuitional faculty. Specifically, it is the intuitional faculty, or the faculty of first truths, as distinguished from the understanding, which is called the discursive or ratiocinative faculty.
We have no other faculties of perceiving or knowing anything divine or human, but by our five senses and our reason.
In common and popular discourse, reason denotes that power by which we distinguish truth from falsehood, and right from wrong, and by which we are enabled to combine means for the attainment of particular ends.
Reason is used sometimes to express the whole of those powers which elevate man above the brutes, and constitute his rational nature, more especially, perhaps, his intellectual powers; sometimes to express the power of deduction or argumentation.
By the pure reason I mean the power by which we become possessed of principles.
