Art is a nuanced term that can be difficult to define in concise terms. One possible antonym for "art founded" would be "mechanical" or "impersonal." This suggests a lack of creativity or soul in the artistic process, and a reliance on formulaic or routine techniques. Other antonyms might include "random," "haphazard," or "unstructured," which imply a lack of coherence or purpose in the work. Alternatively, one could use the antonyms "unimaginative" or "dull," which suggest a lack of inspiration or flair in the creative process. Ultimately, the opposite of "art founded" will depend on the specific context and meaning of the term.
