The term "periodicity" in literature has been employed to convey the idea of recurring or cyclic phenomena, albeit in differing contexts. In George Eliot's "Adam Bede" [1], the word is imbued with an almost philosophical nuance, referring to the recurring patterns of sensations in what is described as "post-time." This use emphasizes the rhythmic, inevitable reoccurrence within human perception or experience. In contrast, Émile Durkheim's reference in "The Elementary Forms of the Religious Life" [2] treats periodicity in a more analytical, causal manner, suggesting that these recurrent phenomena may be attributed to underlying, external factors. Together, these examples highlight the flexibility of the concept as both a poetic device and a scientific observation.
