It's ironic that with this post you literally just made the point that beauty is actually objective. Classical art actually had objective standards (Or an "agreed" truth) based on natural phenomenon your brain finds interesting. When you break many
classic pieces down, symmetry and other geometric qualities are evident. Post modernism, which began in the 1880's, right when Picasso was coming up? Was an ideology meant to destroy these 'restrictive' beliefs, because they believed all reality was subjective, that human views are crafted and that by admitting anything was objective that you are 'privileging' logic, and thus certain people who are logical.
That's not true though,
not entirely. There is subjectivity in beauty, for sure. But there can easily be objective standards we can agree upon for beauty. Ranking a Figure Skating match might be subjective, but
anyone who scores
well in an Olympic match will appear very pleasing to
most people. Because there are AGREED upon standards--and standards which promote things that are pleasing to the majority of people who see them. (And when you dig down into why certain things seem to have these universal qualities of being pleasing? You often find its because, as said above, humans are really just meat machines and a certain part of your brain evolved to find certain things in nature pleasing because those things correlate to something that used to help previous versions of meat machines survive.)
In any case, again, just pointing out the irony that you enjoy art that relied upon objective (Agreed upon) standards for beauty, many of which actually began to develop fairly complex geometry to map why people enjoyed the art. This is why MOST people can see a classical painting and say "that does look interesting/pretty", even if its not their cup of tea (IE not mind blowing, which is where the subjectivity comes in.)....But only a small subset of people who understand the history of Pollock can look at it and even tell its not literal garbage, some mat that painters left their brushes on. (Because Pollock's 'beauty' is based on knowledge of the person and history--ergo, essentially the problem that always arises when people attempt to destroy objectively agreed upon truths, 2+2=5, and what not. Once objectivity is gone, then what's good simply becomes a matter of what the most influential people say is good.)
