What does it mean?

The person who wrote of a building bringing gladness
to the viewer reminds us of the importance of beauty in
human life. Biologists account for the human desire for art
in other terms. They explain that human beings have very
large brains that demand stimulation. Curious, active, and
inventive, we humans constantly explore, and in so doing
invent things that appeal to our senses?fine arts, fine food,
fine scents, and fine music. Art has mostly been considered
in terms of seeking beauty, but there are other reasons
deeply rooted in the human experience that create needs for
art. For one, humans also reflect on the nature of things
and the meaning of life. Visually and verbally, we
constantly communicate with each other; in our need to
understand and our need to communicate, the arts serve a
vital function.
