• • • • • Lecture Summary Four examples of recent theoretical attempts focused on the form of cities are examined in this class. Unlike many of those discussed previously, these have a strong interest in the experience of physical place and have a more complex view of the contemporary city.

They see the city as a democratic institution, and require a systematic quality and a high degree of explicitness so that citizens can participate in constructing the city's form. Kevin Lynch's work follows a trajectory from his interest in the perception and cognition of city form and image (image, remember, is identity, structure and meaning) to setting out the elements of a theory in his later work.

In this work he aims to connect prescriptive, normative ideas to explanatory, descriptive propositions through a series of five performance dimensions: vitality, sense, fit, access and control; and two meta-criteria, efficiency and justice. He postulates these dimensions as ranges rather than standards which can be specified more precisely over time through experiment as in the development of modern science. This requires optimism about human beings' capacity to learn: 'the city is not the manifestation of some iron law but rather part of changing human culture and aspiration.' A glimpse of these performance dimensions in practice are detailed in 'A Place Utopia' within the collection of his last writings. In Christopher Alexander's work there is also a trajectory of ideas about city form passing through optimization, sustaining human contact, complex structures ('not a tree'), and patterns and rules of urban growth.

Alexander's normative view requires a city to be formed by the application of small-scale, commonly understood fields of spatial and social relations. Such patterns have lost their meaning in modern cities, he claims, only to be revived by an explicitly shared new language similar to the widely communicated language of science. Alexander provides the beginning documents for such a language to be built systematically by subsequent practice, experiment and learning.
