The Common Sense Manifesto aims to contribute to sustainable development: the process aimed at creating a society that is economically and socially inclusive and environmentally sustainable. It offers the outlines of a Fourth Way: an alternative to right and left wing ideology that aims to rebuild economics to lead the global economy out of the 2007 economic and financial crisis, by using the world's productive potential for addressing society's social, environmental and economic problems. The manifesto summarizes the shortcomings of traditional economics and presents a framework for a new economics: a social science that gives better insight in how economies function. Moreover, a set of policies is sketched that will help unlock humanity's productive potential for meeting society's social, economic and environmental challenges.
