This text explores the ontological and epistemological distinction between mere heaps of non-communicating components and integrated wholes that exhibit internal unity. The author examines the origins of human sensitivity to this "wholeness," identifying two primary sources for this perception. The first source is subjective impression, which may or may not accurately reflect objective reality. Even when a subjective perception of a whole is erroneous, it can remain functional within human reasoning and action. The second source relates to the ontological nature of things themselves—whether components truly engage in mutual interactions that form a higher unity. The reflection emphasizes that the ability to distinguish between a mere agglomerate and a structured whole is fundamental to our understanding of the world. By addressing the tension between the subjective experience of unity and the objective state of affairs, the text raises significant questions regarding the truthfulness and utility of our mental constructs in relation to reality.
