Literary notes about Functional (AI summary)
The term "functional" emerges in literature with a remarkable versatility, serving both as a descriptor of practical, measurable attributes and as an abstract concept denoting purpose or relationship. In some contexts, it is applied in medical and analytical settings to characterize conditions that are operational rather than structurally anomalous—for instance, describing a case with no discernible functional cause or distinguishing between organic and non-organic nervous disorders ([1], [2]). In philosophical and sociological discourse, the word often conveys an essential yet non-material quality that underpins experiential and rational relations, as seen in discussions of mind and body or social devolution ([3], [4], [5]). Moreover, in literary portrayals of design and aesthetics, "functional" is employed to highlight simplicity and purpose, imbuing objects and structures with a purity of form that is both utilitarian and symbolic ([6], [7], [8]).
