"Liberal" things (4)

I believe the answer is:
arts
'liberal things' is the definition.

This is all the clue.
(Other definitions for arts that I've seen before include "Aesthetic pursuits for rats" , "'Poetry, music, painting (4)'" , "Eg, painting, sculpture" , "Products of human creativity" , "Non-science subjects" .)
