As we perceive reality as a network of relationships, our descriptions, too, form an interconnected network representing the observed phenomena. In such a network there will be neither hierarchies nor foundations. Shifting from the building to the network also implies abandoning the idea of physics as the ideal against which all other sciences are modelled and judged, and as the main source of metaphors for scientific descriptions. The Cartesian paradigm was based on the belief that scientific knowledge could be achieve absolute certainty. In the new paradigm, it is recognised that all concepts, theories, and findings are limited and approximate.
Science can never provide any complete and definitive understanding of reality.
