Neighboring houses of worship on Fifth Avenue in Oakland use art to express faith. Some art is an act of individual expression. Perhaps the poet tries to describe an elusive emotion using a particularly evocative combination of words. A dancer or musician may convey emotion without using words at all. The painter or photographer captures a single frame of time and lets others in the world see the image as it appeared in their own mind's eye.
Some artists intentionally exaggerate an image.
This is called caricature. They reshape it, augment it, to emphasize the emotions the image inspired in them. Some of the Modernists chose to forego realistic images completely in favor of colors and shapes that inspire emotions on a visceral level. In every part of our lives . . . in more forms than we can imagine . . . spanning time, geography, and social class . . . artwork exists. And each work of art helps us wash away a little more of the dust from our everyday lives, and celebrate the soul that lies underneath.
