In literature, "cogency" is frequently employed to denote the clear, persuasive, and logically powerful quality of an argument or discourse. Writers use the term to describe reasoning that not only appears coherent but also carries a compelling force that can win over an audience, as seen when an argument’s underlying thought is said to give it cogency [1] or when a critic notes the irresistible cogency of certain reasoning [2]. It is also deployed to highlight the strength or validity of thought, whether in debates about abstract principles [3] or in more practical scenarios like assessing evidence or conduct [4, 5]. Moreover, the word often serves to distinguish arguments that combine both logical clarity and original insight, lending a robust and dynamic character to the narrative or rhetorical style [6, 7]. Overall, cogency in literature marks the intersection of clarity, logical structure, and persuasive efficacy.
