Writers employ "fundament" in a variety of ways, stretching from the concrete to the abstract. In some works the term designates a physical base or anatomical part—for instance, it may refer to the buttocks, as when a dog's movement is described with its fundament trailing along [1] or in detailed medical and herbal treatises addressing warts, piles, or hemorrhoids [2, 3]. In contrast, other texts use the word metaphorically to denote the essential underpinning or moral base of systems and ideas, as seen in discussions of the foundation of morality and legal principles [4, 5, 6, 7]. Moreover, its usage appears in contexts of sensuality and corporeality, lending an erotic nuance that blurs the line between the physical and the conceptual [8, 9, 10].
