Sculpture is not a fixed term that applies to a permanently circumscribed category of objects or sets of activities. It is, rather, the name of an art that grows and changes and is continually extending the range of its activities and evolving new kinds of objects. The scope of the term was much wider in the second half of the 20th century than it had been only two or three decades before, and in the fluid state of the visual arts at the turn of the 21st century nobody can predict what its future extensions are likely to be.

He is simply pouring out his own inner illness; it is helpful for himself, it is therapeutic.
The sculpture is of an ancient Greek disc thrower, right before the man is about to circle, to throw the disc. It is objective because it clearly shows the activity the man is doing, which no one can debate as it is a sport/activity that most people today would recognize, and would not be confused with any other sport. The man’s physical features and body placement are also objective, and inarguable.
