the quality, production, expression, or realm, according to aesthetic principles,
of what is beautiful, appealing or of more than ordinary significance
to begin to grow or develop into a plant or individual, as a seed, spore or bulb
to sprout, pullulate
to come into existence; create
When in doubt, look in the dictionary, right? I wouldn't necessarily agree with the thesaurus law on the matter of art as only elevating that which is not ordinary, hence beautiful, but anyone attempting to define this word deserves a listen (at least because of their valiant attempt to try).
The quest for what is inside our heart, that ambivalent art we seek and the call to arms to sprout, create, begin!
