This philosophical reflection delves into the ontological nature of unity, making a strict distinction between true unity, which is independent of any observer, and unity that finds its source solely within the observer’s perception. The author argues that a mere plurality remains a disorganized heap unless it is unified into an organic whole through the establishment of a "subject." This subject acts as the singular source of the whole’s integrated activities. Crucially, the process of unification cannot be achieved through the external arrangement of parts; it must engage the internal dimensions of its sub-components. Consequently, these components cannot be inert or "dead" elements but must themselves function as unities on a lower level. The text critiques classical atomism for its mechanistic assumption that elements connect via external hooks or surfaces. Instead, it posits that higher unity emerges through the active involvement of the subjects of lower-level components. The inquiry concludes by identifying the unresolved question of the origin of such subjects at the most fundamental level.
