    Dos Santos, Miguel F. (University of St Andrews, 2013-11-30) - Thesis
    The first-order debate about the definition of art focuses on the ‘What is art?’ question and those who engage in it answer the question by putting forward definitions (or at least characterizations) of art. The second-order ...
