A biológia fogalomrendszerének néhány problémája 3. rész. A fogalmi konstrukciók fontossága

Juhász-Nagy, P. Some problems of a conceptual system in biology. Part 3. Importance of conceptual constructions. The starting statement is that the concept "environment" (incl. ecological environment) is still essentially undefined, and, therefore, several important questions (e.g., how habitat, niche and environment are related to one another) cannot be answered properly. The only way to find a better résolution is to follow strictly the series of scientific activities ("what does de facto the scientists do?"), i.e., to study carefully the relations between scientific manipulations (e.g. observation, sampling, data-processing, etc.) and rather well-defined concepts (e.g., observational unit, topographical neighborhood, sampling space, etc.), by which a number of fairly acceptable "operation - concept" constructions can be established. In conclusion: the "purely verbal pseudo-definitions" of textbooks are hopeless; instead, useful conceptual constructions are needed.
