Validation- an interaction between Art and Language

Validity is the property of anything that obeys to the rules of logic. Unlike truth which is the correspondence between a certain statement and reality (or more or less aparently verified facts), to define something as valid one only needs language and a set logical criteria to qualify the interaction between statements as valid. The process of validation as a consequence implies the definition of the language and a set of rules (criteria). To classify a text as valid one doesn’t need to know the meaning of each concept, just the language and its most basic elements. If something is valid it means that whatever it is saying it says that according to the rules of the pre-existing system.
Generally there are two general methods of validation of a statement: the classical and the scientific. The classical method is deductive (it starts stating generally accepted premisses) originating specific (usually obvious) conclusions. The scientific method of validation is experimental. It consists on verifying that a certain phenomena happens in a particular case and, through the repetition of that experience in a controled environment, concludes that those properties verified in those particular situations are actually generally applyable.
Baring this in mind I would like to explore the process of validation of Art via art school, criticism, curation and philosophical (or any other external) references.
