Abstract
The Spanish philosopher Gustavo Bueno coined the expression “substantive arts” to refer to those arts that do not serve any immediate, mundane or practical purpose. In this paper, I briefly present this idea and put forward a definition of the substantive arts as an alternative to those used until now. Starting from the assumption that since the end of the 18th century there has been a set of arts that have their own substantivity, I expound on certain criteria widely used as distinctive features to define the substantive arts. I subsequently put forward an alternative intensional criterion to characterize the substantive arts. To end, I draw some corollaries following from the application of this criterion.
