Morris Weitz, in his The Role of Theory in Aesthetics questions the art theorist project of 
defining and delineating the concept of art. He finds the search for a set of necessary and sufficient 
conditions for something to be defined as art problematic. Art is an open concept according to Weitz, 
and he states that: “the very expansive, adventurous character of art, its  ever-present changes and 
novel creations, makes it logically impossible to ensure any set of defining properties. We can, of 
course, choose to close the concept. But to do this with “art” or “tragedy” or “portraiture,” etc., is 
ludicrous since it forecloses on the very conditions of creativity in the arts.” He expounds his view 
by referring to Wittgenstein’s ideas about language-games from his Philosophical Investigations. We 
should shift our questions from what is art to how do we use the concept art? How is the word ‘art’ 
used in language? We should not look for the last and final definition of art but for how artworks 
resemble each other, looking for family resemblance. We could find some paradigm cases of art to 
use as a measuring stick, but that is not all-encompassing. 
Furthermore, Weitz mentions two ways of elucidating the usage of the concept of art. On the 
one hand, there are descriptive usages; when we describe something as 'art' which is analogous to 
describing something as a chair. The descriptive questions entail what we do when we might find 
similar conditions, properties that are present in most artworks, rather than necessary conditions for 
a work of art to be considered art. On the other hand, evaluative usage such as “is this good art?” 
concerns how we praise a work of art as a work of art, what conditions constitute an excellent work 
of art? In his view, these usages of art are often confused, and this creates problems for the definition 
of art. Weitz’s clarification is, however, not bulletproof since it is from 1956, and one could say that 
the descriptive usage no longer applies. If we can, in the year 2020, use the word art for anything, we 
have to rethink the open concept of art. 
If taken this way, theories of art are saved from pointlessness or inanity. Diving into the use 
of  the  concept  of  art,  therefore  opens  up  a  whole  world  of  possible  ‘living’  definitions  of  art, 
definitions that are ‘forthcoming’. The end of art is, according to my reading of Weitz, a false view 
of art: it entails looking at art as a closed concept, defined logically, which is impossible since art is 
an empirical concept.  
Is it the task of philosophy to define art? On Weitz’s view, yes – but in a different sense than 
before.  Art  might  be  more  active  than  ever  because  of  the  false  idea  of  sufficient  and  necessary 
conditions of art have been uncovered. The musician does not have to be a virtuoso, and visual art
