    SYNONYMS reason, intuition, understanding, judgment. These nouns refer to the intellectual faculty by which humans seek or attain knowledge or truth. Reason is the power to think rationally and logically and to draw inferences: “Mere reason is insufficient to convince us of its [the Christian religion's] veracity” (David Hume). Intuition is perception or comprehension, as of truths or facts, without the use of the rational process: I trust my intuitions when it comes to assessing someone's character. Understanding is the faculty by which one understands, often together with the resulting comprehension: “The greatest dangers to liberty lurk in insidious encroachment by men of zeal, well-meaning but without understanding” (Louis D. Brandeis). Judgment is the ability to assess situations or circumstances and draw sound conclusions: “At twenty years of age, the will reigns; at thirty, the wit; and at forty, the judgment” (Benjamin Franklin).

    If you follow reason far enough it always leads to conclusions that are contrary to reason. — Samuel Butler

    Reason involves the ability to think, understand and draw conclusions in an abstract way, as in human thinking. The meaning of the word "reason" overlaps to a large extent with "rationality" and the adjective of reason in philosophical contexts is normally "rational", not "reasonable".

    In action, reasoning involves a conscious attempt to discover what is true and what is best. Reasoning thought follows a chain of cause and effect, and the word "reason" can be a synonym for "cause".

    As one way of coming to conclusions, reason is often contrasted to emotion, tradition and faith—the "rationalist" argument being that reason is the more reliable way to arrive at that truth.

    The concept of reason is closely related to the concepts of language and logic, as reflected in the multiple meanings of the Greek word "logos", the root of logic, which translated into Latin became "ratio" and then in French "raison", from which the English word "reason" was derived. In contrast to reason more generally, language refers not to the thinking as such, but to the communication or potential communication of rational thoughts.
