There is different art for different people. Some art is not for us but for someone else. Sometimes it not for us yet but it will be the art we need and admire in the future.
Art is a tool that can be used in the same practical manner.
If loneliness catches busy city people a Hopper might help out. We can see that other people are lonely too and we may find the courage to say “Hello” and connect to feel less lonely together.
Same for all other great art. While some will remember us that uncertainty is part of human existence, some bottle enough happiness to bring us through bad times.
Art is there for all of us in one way or the other.
