Some Fundamental Issues in “Design” Definitions of design Normative logics (modal logics) –predictive models inherently risky not usually quantifiable learning by failure (Petroski) Complexity - “bounded rationality” –(Simon) ‘the meaning of rationality when the complexity of the environment is immensely greater than the computational powers of the adaptive system…’

Hierarchy - composition - “independence” –“emergence” in complex systems? (Systems Theory) examples –$10 worth of chemicals in jars vs. human being –buffer overflow –courseware –…… –“ontogeny recapitulates phylogeny” reduce complex problems to those previously solved

Social Values –we can => we will ? descriptive vs. normative argumentation science vs. ethics –larger social implications and consequences deskilling –economic implications, family structure and crime the “AI” metaphor –spiritual implications?
