The Constrained Nature of Human Imagination as Evidence for the Physicality of the Psyche

This paper contends that the limits of human imagination provide strong evidence that the psyche operates as a physical mechanism. Although imagination is often viewed as boundless, it is in fact constrained by the mind’s structural and functional capacities. These constraints appear in our inability to conceive ideas beyond fundamental boundaries—such as imagining “beyond nothingness”—or to form concepts entirely detached from empirical or neurocognitive grounding. By analyzing how imaginative capacity depends on empirical input and cognitive architecture, the study argues that these limitations expose the physical substrate of mental processes, challenging metaphysical conceptions of the psyche.
