My definition of vague music: Aaron Copland

Composers follow concepts and principles; theorists find and follow rules alone by themselves.

Composers follow more concepts and principles than rules; rules are followed principaly by theorists who neglect the philosophical way to decompose a piece in concepts and principles, without breaking its soul.

Oftentimes those who you call  « undisciplined «  are being disciplined according to their own principles, or other people. Discipline , as the faculty to follow rules through, is not an absolute value, it’s just a value..

It’s not about treating her like a princess or not; 
it’s about being first a king, for this story get some sense.

When we say we create the reality we are not using the language in the same sense as when we say that the reality is absolute in itself.

Philosophy, as the foundation of science,  does not require scientific experiments;
but in order to be a philosopher it will be scientifically  necessary 
that you become your own lifetime experiment.
