The term "thinking" in literature functions as a versatile narrative tool, revealing characters' inner deliberations and shaping plot dynamics. In many texts it appears as a window into private reflection—for example, a character may internally dismiss an idea or plan, as seen in Melville’s rejection of association in [1] or Chekhov’s depiction of a man pacing the room lost in thought in [2]. At times “thinking” is used to signify casual musings or spontaneous plans, such as considering a future picnic in [3] or speculating over personal relationships in [4] and [5]. In other contexts, the word underscores a calculated or strategic moment of decision-making, evident in the subtle irony of thought in Carlyle’s commentary in [6] or in Pinocchio’s impulsive judgment in [7]. Across these examples—from Thucydides’s weighty reflections in [8] to John Dewey’s discussions of intellectual processes in [9] and [10]—“thinking” encapsulates the fluid interplay between conscious reasoning and the unbidden stirrings of the mind, making it a critical element in character development and thematic exploration.
