Creativity without which our world would be what? (3)

I believe the answer is:
art
'creativity' is the definition.
(creative work)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for art that I've seen before include "Works of creative imagination" , "''... is long and life is short''" , "are old-fashioned" , "Skill, craft" , "Creative works; skill" .)
