Contradictions in the world


The universality of contradiction. According to Mao Zedong “contradiction exists in the process of development of all things.” Lenin followed the same way of reasoning by stating that there are mutually exclusive, opposite tendencies in all phenomena and processes of nature. Does this mean that things come into being/ are referred to/ are defined only as opposites to other things? 

This way of reasoning is related to the anthropologist’s Claude Levi-Straus, who emphasized the binary oppositions between elements, at the language and culture levels, present in 187 myths of societies around the world. 

My question here is: If this kind of reasoning is correct, then which was the first element to be defined on its own, not as an opposite to something else?
