From a certain point of view

How does our perspective shape our outcome when it comes to the input in creating something? In my opinion, our thoughts, experiences, memories, and various surroundings stimulate our imaginative properties and perceptions on what one thinks about life and how best to express this through the artistic process and outcome. It is the wonder and mystery of the human condition, the uniqueness of each individuals' perception on a given experience as well as an audience and as a contributor which makes the creative process fascinating. But how can one measure the aesthetical benchmark, if indeed there is one? If aesthetics represent beauty, the beauty and magnificence of creation, is there a measurement for an objective agreement on what is truly significant to our civilisations needs? 

In other words, in a world of individuals, human beings with unique experiences and environments, the idea that there is truly an artwork and something significant that all agree upon must be absurd! Surely in our modern day society of the 21st century, the response of the individual, in part, is dictated by the internet and the exposure to popular culture? My question is: does the artwork contribute to a higher ideal, one that is noble, reflecting a moment in time and history, either as a documentation or inspiration of one's surroundings? 

Is the art work moving us as an individual to respond? My answer and argument is that the human condition will respond in one way or another regardless, and so, this cannot be a criterion for artistic product to be of value. So what is the criterion for the artwork to be worthy of our attention and considered a contribution to our civilisation (in the hope that it adds to the positive, creative evolution of the human species)? I can only assume that 'beauty is in the eye of the beholder'. That is, perspective plays a great role in what an individual deems to be a valid cause and contribution. That said, how does this process work collectively on a global scale?
