Abstract
The severe accident at the Fukushima-Daiichi nuclear power plant caused by the March 11 Great East Japan Earthquake in 2011 was a typical disaster in the age of “trans-science,” which means the situation that science and politics are closely connected and inseparable. The stage of trans-science requires a philosophy of trans-science instead of a philosophy of science such as logical positivism. I would like to characterize norms for techno-scientists in the risk society as RISK, which includes Regulatory deliberation, Intergenerational ethics, Social accountability and Knowledge-product liability.
