Modern man is asked by the zeitgeist of the times to live life open-minded and accepting of multiple possible world views and perspectives. In today's pluralistic culture of the West, to believe that there is one correct view on life and morals is considered closed-minded. Relativism in the West opens our minds to multiple simultaneous and contradicting truths. Multiple perspectives on life and truth are valued even if contradicting. This type of mindset can be confusing, but confusion is the home of the modern mind. Instead of confusion one can call it possibility, potential, freedom. In this state though, our perspective on life is much like this painting by Picasso, The Poet. Its hard to know what we are looking at, but one is supposed to be ok with that and find the beauty in ambiguity. This is the mind of modern man, he doesn't know what we are or where we are going but isn't that kind of pretty in itself, just the weird wonder of it? Concrete meaning and definite truths are blurred and blended. What is truth? What is man? What is God? What is reality?
Cubism paints reality from multiple perspectives at once, after all one perspective can't be right. All perspectives at once are true even if this leads to no perspective. This type of painting can be a metaphor for the mental state of how reality appears to the modern man who is open to all-truths since no truth is absolutely true to everyone. Being open to all-truths, even contradictory truths is like having no truth.
Representational art traditionally has one viewpoint. Traditionally societies have had a majority viewpoint. Art tended to have meaning and represented real things and ideas. As in cubism, the modern liberal mind tends to shun a single narrative of truth unless that narrative is that there is no one truth. Ambiguity, open-mindedness, pluralism, "tolerance", is the ideal. I think that is why modern art is so ambiguous and hard to understand. Modern Western society thinks life should be hard to understand, at least a life with meaning. It tends to say that each person makes his or her own personal meaning and no one narrative encompasses all as true.
Then we have abstract expressionism. This type of art seems to promote the idea that meaning is not important in life, only self-expression and freedom to do whatever you feel. The need to communicate ideas and connect to others in a rational way is not important. What seems to be encouraged is the expression of the self at the expense of a shared experience with others with actual understood meaning. Can you think of any people in your life that live this way?
Am I reading to much into art and what its style promotes or can you see that values of a society materialized in the artworks it creates?
