Cognitive division of reality is effectively the basis of all abstract ideas.
This is largely hidden within everyday thinking, but our ideas are inherently based on the mind dividing, categorizing and labeling the world. No conceptualizations of reality would be possible without such cognitive acts – albeit they are so deep within the mind’s operations that they almost never surface as conscious thoughts. Even the idea of their existence is possibly nothing more than the outcome of conventional reasoning; it seems likely that we have never consciously reflected on the matter, having uncritically assimilated cultural perspectives of reality since birth.
