Our awareness of brain functions and ecological systems has increased greatly during the last century and literally extend the 'self' to inner and outer boundaries which demand a revision of our approach to concepts of social value. Ideas of social reproduction and growth can now be compared more globally and value systems are less likely to resist the creative intervention of individuals and ideas from other cultures. Disciplines which were built upon fixed social values, such as good taste in architecture, must continue to re-appraise their relationship to other cultures and become transdisciplinary rather than simply 'good communicators', as with multidisciplinarity approaches in the past.
