As a legacy of the Modern Movement, there is still resistance to the idea that architecture should offer aesthetic satisfaction. Historically cities provided emotional satisfaction through symbolism and aesthetic pleasure. Aesthetic experience is related to the principle of rhyme, a principle which can be expressed through pattern, symmetry and harmony. These concepts are possible in the visual milieu because the mind attributes 'weight' to visual phenomena. The interaction of perceptual weights may result in one of these aesthetic systems. This paper suggests that it is time to return to a systematic consideration of aesthetics in architectural and urban design.
