The term "qualitative" has been used in literature to denote distinctions based on inherent characteristics or kinds rather than mere numerical measures. For example, Kant juxtaposed “quantitative (material)” and “qualitative (formal)” aspects in his discussion of perfection [1], while various authors contrast qualitative differences with quantitative ones to underscore change or variation in kind [2, 3, 4, 5, 6]. In both scientific and philosophical writings, qualitative observations are used to describe differences apprehended by the senses—whether in the context of sensory content organization [7], the lack of significant variety in nature [8], or the health status of an individual as revealed through analysis [9]. Moreover, thinkers like John Dewey have linked qualitative aspects to the completeness of a situation’s appeal [10], and sociologists have defined qualitative differences as the presence or absence of specific traits among individuals [11]. Even in more abstract treatments, such as in Plato’s Timaeus, phenomena are sometimes imagined without their qualitative differences, reduced entirely to mathematical abstractions [12].
