You will never get to the irreducible definition of anything because you will never be able to explain why you want to explain, and so on. The system will gobble itself up.
You want accuracy, but not representation. If you know how to make the figuration, it doesn't work. Anything you can make, you make by accident. In painting, you have to know what you do, not how, when you do it.
They will always tell you that you can't do what you want to do, but you can do what you want to do. You just have to believe in yourself. The system is to bring you down, but you can rise up.
