Literary notes about Incidental (AI summary)
In literature, incidental serves as a term to denote elements that are secondary or peripheral yet possess a significant, albeit subtle, effect on the overall narrative or argument. It is frequently used to describe details or occurrences that, while not central to the main theme, contribute to color, context, or a broader understanding of the subject. For instance, a fleeting comment that enriches a character’s portrayal or an auxiliary process that underpins a primary event may be termed incidental ([1], [2]). In more analytical or philosophical writings, authors use the word to distinguish between what is essential and what happens merely as a by-product of more dominant phenomena ([3], [4]), highlighting that even non-essential elements may offer useful insights or have consequential impacts ([5], [6]).
