I spent almost a lifetime trying to understand art. I read many books and spoke to many experts and I still did not understand it. I eventually realised, that this was a good thing.
If it is art, it will stimulate. Otherwise, it is just some colours, noise, an assembly of inconsequential objects or just movements of the body. When we look at something objectively we use the mind.
The mind feels nothing for it’s a cold analytical thing. Art touches our being, and that is a matter of the heart. Matters of the heart cannot be understood, merely experienced.
What a dreary place our world would be without artists.
