Art is all about perspective and expression. Many artistic endeavors are the artists interpretation of nature is saying to them specifically; their immediate surroundings. Whether that be abstract or of a more conventional sense.
As artists come to the need to express this is born from their soul and what needs to get outside of them and into the world. What one artists sees and feels is needed to be created is has individual as that person is. Any one artists creation is a symbol of what surrounds that person in any given time.
I agree that “artistic” is sometimes an baseness of knowledge because said artist may not have the knowledge or talent to create a perfect circle, however they can certainly give my mind the illusion that they have.
Without art education is our main stream of education means not having a rounded education at all. what is the point of dampening a creative mind or a persons need to exploration? Art provides the avenue to make substantial who we are and why.
