Aesthetic is constantly remoulded by the brainwashing effect of advertising. After physiological perception all our interpretations enter the visualization process of an object to formulate the projection we call 'art'. Good art gives one a sense of self-containment and wholeness through its compelling integrated visual unity. Art is the symbolic expression of man's relationship with the Universe. Like anything else in life, art MUST change.
Art is the portal to other levels of human consciousness.
Nothing is more harmonious and tranquil than a circle. But yet we live in rectilinear cubicles. Our aesthetic preferences change throughout life along with our evolving personality maturation. Maybe someday I'll prefer Lawarence Welk to Disco. Color harmonies are seasonal.
