Structuralism

This focus's on the opposites such as black and white, yet demonstrating the idea that there is more to just black and white, such as good and evil, it's not as determined to be just one or the other. Its how we make meaning of the word, Life and death, is there and in-between? hot and cold not everything is one or the other, what would we describe as hot? maybe as hot as the sun, or as cold as the north pole, warm is the in-between, the same with light and dark, when is a room completely dark or completely light, in reality complete light would be blinding and humans would not be able to function.
