This shift to cubism was very important because it gave one a medium in which to present a non-objective representation with cubic forms. It gave a freedom to render reality in a way that fit each individual person. It also represented the notion that reality was not a fixed thing to be rendered, like naturalism thought, but rather reality is how we perceive it. If we render reality a certain way then that is how we perceive and interpret reality. Cubism gave one the freedom to portray reality as they have interpreted it which is fundamental to artistic freedom.
