The word "egoist" appears in literature with a variety of nuanced connotations, ranging from ethical analysis to vivid character portrayal. Philosophers like Schopenhauer depict the egoist as trapped in a self-centered world, where external hostilities are met only by an inward focus on personal good ([1], [2]). Similarly, ethical and existential discussions by Henry Sidgwick and Nietzsche question the merits of deferring present pleasures for greater future gains and highlight human tendencies to prioritize habitual self-interest ([3], [4], [5]). On the literary front, Dostoyevsky employs the term both playfully and critically as his characters acknowledge or condemn self-interest, while Chekhov uses it to underline the complexity of individual nature ([6], [7], [8], [9], [10]). Furthermore, titles such as Meredith’s The Egoist indicate that the concept has long been a subject of both literary intrigue and scholarly discussion ([11], [12], [13]).
