Peters combines a chaos/complex systems framework with the Austrian school of economic thought to explain our lack of market understanding. He develops a strong case that the most pressing problem for investors is not a matter of specific models but of determining how to assess risk in a complex and uncertain world. Peters draws important distinctions between risk, uncertainty, ignorance, vagueness, and ambiguity, and in doing so, shows how the subtle meanings of words can provide immense value in explaining the market environment. He also resurrects the Austrian school's emphasis on subjectivism and makes it come alive within finance. (Financial Analyst's Journal)
