Across literature, "inseparable" is employed with both literal and metaphorical nuance to emphasize bonds that are unbreakable or conceptually united. Philosophers and political theorists use the word to denote the essential unity of abstract concepts, as when Rousseau [1, 2, 3, 4] and Plato [5, 6, 7] argue that justice, happiness, or duty are inherently connected, or when Kant [8] and Schopenhauer [9, 10, 11] insist on the indivisibility of certain existential or metaphysical elements. In contrast, novelists and poets often describe personal or emotional ties that cannot be severed, whether in enduring friendships and companionable relationships noted by Tagore [12], Poe [13, 14, 15], and Guy de Maupassant [16, 17], or in the delicate interplay of beauty and melancholy in Poe’s work. Even in more scientific or analytical texts, "inseparable" signifies components that cannot be meaningfully isolated, as seen in Locke’s [18, 19, 20, 21] discussion of spatial parts or in Darwin's anatomical observations [22]. Thus, "inseparable" serves as a versatile literary device that unites diverse realms of thought—from the concrete bonds of human companionship to the abstract necessities of philosophical argumentation.
