This text examines why perception and sensory experiences are problematic starting points for philosophical inquiry. It argues that sensory organs respond only to minute external stimuli, such as energy quanta or chemical ions, which are subsequently processed into information. A crucial role in this process is played by the active intervention of reason and understanding, through which we perceive the world as a collection of objective realities. Consequently, the world as it appears to us is, to a significant extent, our own construct. The author emphasizes that a vital philosophical task is the ability to distinguish between mere heaps or aggregates of elements—which may be organized or socialized within a biotope—and genuine wholes characterized by internal unity. This distinction leads to further fundamental philosophical problems. By highlighting the complexity of the relationship between the external environment and human consciousness, the text challenges naive empiricism and calls for a deeper investigation into the cognitive processes that shape our experience of reality.
