This text examines the fundamental significance of concepts and conceptual constructions in defining scientific disciplines. The author argues that although concepts allow for precise differentiation between similar phenomena, they lack inherent boundaries within their logical interconnections. For science to function effectively, it must rely on constructed models that are intentionally isolated and indifferent to one another. This neutrality of thought constructions allows for the establishment of clear boundaries of competence between various fields of study. Since the natural world contains no sharp divisions but only continuous transitions, any scientific classification must be based on human consensus and convention. While everything in the actual universe is interconnected, connections within the modeled world of science must be deliberately constructed through conceptual contexts. This isolation of models prevents uncontrolled overlap and ensures methodological stability. The study emphasizes that without these intentionally built constructions, professional specialization would be impossible, as natural reality offers no fixed guidelines for the systematic categorization of knowledge about the world.
