Human social life is constrained by various norms: Some prescribe and others prohibit actions. Some do so in a context-dependent manner, others universally. Norms that fundamentally question how people ought to live are usually called ethical norms. They are distinguished from cultural norms such as customs and manners, or institutional norms such as laws and school rules. Ethics is often treated as a classic example of problems that cannot be resolved from the perspective of science and technology. In this chapter, however, we examine how it might be placed within the symbol emergence systems theory.
