In literature, the term "training" appears in a remarkably versatile spectrum of contexts, reflecting diverse modes of human endeavor and development. It may denote the cultivation of artistic or practical skills, as in the refinement of a voice for performance or the development of musical aptitude ([1], [2]), or the disciplined regimen needed for physical, military, or even intellectual pursuits ([3], [4], [5]). Authors employ the word both in its literal sense—as in instructing a servant or soldier ([6], [3])—and metaphorically, to illustrate moral or cultural formation, as when training becomes a lifelong method of shaping one’s character and capacity for reason ([7], [8]). This dual usage underscores literature’s broader concern with the processes of education and self-improvement, whether through formal institutions, like colleges and academies ([9], [10]), or through the subtler, habitual exercises of daily life and thought ([11], [12]).
