"...a fuller, deeper meaning..."
A quote from Henry Moore that I stumbled upon several months ago, and then saw again yesterday, that really accentuates things I believe in:
"All art is an abstraction to some degree. Abstract qualities of design are essential to the value of a work, but to me of equal importance is the psychological human element. If both abstract and human elements are welded together in a work, it must have a fuller, deeper meaning."
Henry Moore, from Henry Moore: Writings and Conversations, A. Wilkinson.
