Information and Communication Technologies (ICT) have created best conditions for grows of knowledge societies. An emerging global information society serves to building global knowledge societies as source for further development. Conventional paradigms of sciences starts to be more blemish and prone to redefinition of there foundations, understood as scientific knowledge. The perspective of knowledge and ideals of rationality are both heavily influenced by a new contemporary scientific thinking, through tools, inherent of autonomy and uncertainty. A new understanding of the world in terms of open dynamic heterogeneous uncertain systems is needed. Among the conclusions: classical rational reasoning is mainly aiming at effectiveness, not at uncertain knowledge processing, because of its temporality (mainly its ineffectiveness in dealing with future events); a bounded-rationality approach enables both, better economic models and better modelling, being based on trends in economic modelling as well as on agent-oriented software engineering
