Living in a certain place and time, we tend to think within a certain set of values and act upon them as if they are universal. And we use our critical skills to judge ‘everything’.
It is a set of values that is a sum of the whole society, and living by its rules is more or less part of the game. The game of a society that keeps a certain balance between individual desire and the common good.
But that does not mean those values are universal. That they apply everywhere. And in all times.
That just means they are good in a certain context. The context of that specific society. In that specific time in history.
Art is also criticized in the spirit of that age. But one of the characteristics of art is, that it is a search for new patterns that fit in a greater whole, which go beyond the context of that specific society in that specific time.
