AESTHETICS OF ARCHITECTURE 103 As long as the process of economic production, which was simply the procurement of items of survival, was on some sort of communistic basis, competition was non-existent because the tribe as a whole and each individual were directly experiencing the struggle for survival that existed between man and nature in their day-to-day life. Marx has observed that in order to produce, the people enter into definite connections and relations with one another and only within these social connections and relations, does action on nature, production, take place. The development of feudalism and capitalism isolated man from the community and from his life support system. Advanced capitalism utilizes technology and labour to extract, from the life support system, its own profit. The community's access to its own life support system is thus taken over by individual groups. A communist culture must restore the balance. The role of a communist culture will be to ensure the community's existence as a group which is pitched against nature for survival and not against parts of itself. It is necessary to replace patterns of ownership so that all indispensable resources belong to the community at large. The paired family must cease to be the basic unit of social organization. Ideal of the Future These assumptions govern the fundamental assumptions about the architecture, of the future, just as they governed the history of architecture of the past. The map of the human settlements of the ages in the past and future are a physical representation, a symbol, a photograph of man's mode of survival and how the culture of each age has regulated the basic tripartite relationship between man, community and nature. In order to illustrate this principle across a span of time, three settlements symbolizing the past, present and the future have been selected. The past is symbolized by a tribal village layout, the present by the capitalist city of today and the distant future by Ultimate City which is also the last city on earth, a symbol of an entity which is constantly developing as part of the dialectical process. It is conceived as the last city because it is also an ideal which undergoes a qualitative change to become something else other than an urban settlement or city. In applying the term aesthetics to architecture, it has to be interpreted in the historical context to show how a particular society, depending upon its stage of development, generates its own architectural forms and that changes in the base of a society cause
