Art is especially concerned with the development of visual perception and aesthetics. It is a means of communication and a means of expressing ideas and feelings. Art encourages personal expression, imagination, sensitivity, conceptual and critical thinking, powers of observation, an analytical ability and practical attitudes. It leads to greater understanding of the role of the visual arts in the history of civilisations. It will widen cultural horizons and enrich the individual. It complements literary, mathematical, scientific and factual subjects.
