There are several different forms of comparability involving prudential values. Comparisons of values in the abstract, of realizations of some value, and of options which realize values, are distinct, and related, though not mutually exclusive. Furthermore, if rough equality is thought of as an evaluative relation in terms of which comparisons can be made, it does not imply incomparability. If it involves epistemic vagueness, this does not imply incomparability, since our not knowing which relation holds does not imply that no (...) relation holds. Finally, if it is true to some degree that some relation holds, there may be some fuzzy ordering. Given that we may not be able coherently to talk about degrees of truth, I propose an open-ended comparability condition, which takes account of rough equality, epistemic vagueness and fuzziness.

A recurring question about cost - benefit analysis concerns its scope. CBA is a decision-making method frequently employed in environmental policy-making, in which things which have no market price are treated as if they were commodities. They are given a monetary value, a form of price. But it is widely held that some things cannot be meaningfully priced, thus substantially limiting the scope of CBA. The aim of this paper is to test some aspects of this broad claim, focusing on (...) problems of incomparability and incommensurability. In particular, the role of rough equality as a putative form of comparison is investigated. I argue that while an assessment of the full significance of rough equality for practical decision-making awaits resolution of a number of important technical questions, it does not provide a strong enough form of comparison to support CBA.

In this article, we present a contextually embedded choice theory. Using concepts and tools of poset mathematics, we show how to include in rational choice theory cultural and social effects. Specifically, we define some choice superstructures, seen as choice set transformations imposed by cultural and social norms. As we shall argue, these transformations can be of help to explain choice behavior within different contexts. Moreover, we show that, once choice superstructures are taken into account, some well-known results about maximizing and (...) optimizing behavior are easily confirmed and some insights on intransitive choices may be phased out.

This essay examines D. G. Ritchie's claim that Principally, it endeavours to determine what Ritchie means by and what kind of utilitarianism he thinks evolutionary theory vindicates. With respect to the kind of utilitarianism vindicated, I will show how he tries to fortify Millian liberal utilitarianism with new liberal values such as self-realization and common good. Ritchie's intellectual debts were eclectic and included mostly Mill, T. H. Green, Hegel and Herbert Spencer.
