What are the four fundamental dogmas of conceptual art?

a) The work of art is an idea or concept before it is a material object.
b) Conceptual artists deliberately blur the boundary between art and language by defining the artwork as an idea or concept. For them, the authentic work is the idea, and this influences the materials used.
c) They censor the commercialization of art since they defend the work of art as the idea and not as the material.
d) Conceptual artists try to disrupt the process by which the possibility of buying art translates into social position and cultural authority.
