[Goguen, 1969]Finally, let us mention the so called principle of incompatibility. The essence of this principle is that as the complexity of a system increases, our ability to make precise and yet significant statements about its behaviour diminishes until a threshold is reached beyond which precision and significance (or relevance) become almost mutually exclusive characteristics. It is in this sense that precise quantitative analyses of the behaviour of humanistic systems are not likely to have much relevance to the real-world societal, political, economic, and other types of problems which involve humans either as individuals or in groups [Zadeh, 1973].It isn't difficult to intuit how the limits and complexity of our present culture tend to displace our attention from the conceptual area of production to that of transformation. Design, as much in the overall specifications for a project as in the design of the details, presents itself with reference to knowing displacements, that is, the conveying of multiplicities, contradictions and differences to temporary equilibriums. Actual realizations and designs on papers are the place where reflections consist; the reflections matured in several technological ambits appear in terms of sums of experiences and solutions "shifted" from their own place of origin to the detailed synthesis that rules the assembling. [De Rubertis, 1994].We pose the final question: how can fuzzy logic, which finds its reason for existence in the interpretation of the reality and exalts the "shifts", point towards the architectural process?...
