This chapter seeks to account for the nearly complete absence of warfare from medieval Iceland and its sagas. It argues that a single logic dictated both the embrace of feud as a socially constructive idea and the rejection of war as an abomination. Drawing on anthropological examples and analyses, war is defined by contrasting it with feud; the bond between war and state-formation is emphasized. War presupposes political centralization and differentiation, which Icelanders, committed to the reciprocal logic of feuding, resisted. According to the sagas, ideological opposition to war manifested itself in abortive attempts at political consolidation within Iceland, in confusion and substitution in the face of war elsewhere (in Norway, England, and North America), and in failure to contend with burgeoning warlike activity in thirteenth-century Iceland. Tensions between state-centric warfare and state-resistant feuding existed in historical reality, however, not only in saga accounts of this history; and in reality, tensions could not always be resolved. Uchronia provided a tool for creative, retrospective textual resolution of problems that could not be overcome in practice. As demonstrated by the Icelandic law code, Grágás, the past thus became the path-dependent product of the future. Uchronic ideology worked to emend any perceived historical ‘errors’: any symptoms of war that could not be suppressed in reality were, instead, overwritten and repressed in text

This paper studies the effect of fractional volatility on path-dependent options, which are highly sensitive to the volatility structure of a targeted underlying asset process. To this end, we propose an approximation formula for average and barrier options when volatility follows a fractional Brownian motion. Furthermore, using the analytical formula, we investigate the impact of the Hurst index on option prices. Overall, our important finding is that when the maturity is short and speed of mean-reversion is slow, the impact of the Hurst index strongly influences the option prices and that is non-negligible. This is an important lesson for practitioners who uses standard Brownian motion.

Abstract Reasoning is the iterative, path-dependent process of asking questions and answering them. Moral reasoning is a species of such reasoning, so it is a matter of asking and answering moral questions, which requires both creativity and curiosity. As such, interventions and practices that help people ask more and better moral questions promise to improve moral reasoning.
