 Aesthetic value. Finally, epistemic values of unity may rely on subsidiary considerations of aesthetic value. Nevertheless, consideration of beauty, elegance or harmony may also provide autonomous grounds for adopting or pursuing varieties of unification in terms of simplicity and patterns of order (regularity of specific relations) (McAllister 1996, Glynn 2010 and Orrell 2012). Whether aesthetic judgements have any epistemic import depends on metaphysical, cognitive or pragmatic assumptions.
