This article aims at calling on conventional social science and economics to reflect on their past conducts, which have never considered the human itself-the voluntary agent creating a system-in stugying the socio-economic system. I have declared for years that every human being can become an entrepreneur, namely economic agent. If everyone is entitled to capital resources that would support him or her for life, everyone could enjoy economic liberty throughout their lives. Recently, while the science of complex systems has been introduced into economics, there is another radical and innovative idea called 'internal observation' in the science of complex systems. I recently discovered that my idea has almost the same logical structure as 'internal observation.' This idea fundamentally gets over the Cartesian cut such as materials and mind, body and consciousness, and then approves the 'internal observation' of a material itseif: its voluntary and emergent property. This theoretical approach can explain such a 'mystery' as the generation of materials, evoiution of the cosmos, emergence and evolution of the life, and generation of human consciousness, not treating them separately but continuously and unitarily. Once one applies internal observation to social science and economics, it is obvious that he inevitably finds out the dynamical emergent property of the individual human creating the system voluntarily and requires a new academic system that can secure and ensure its voluntary property to the fullest.
