This paper is a critique of Kenneth Arrow's thesis concerning the logical impossibility of a constitution. I argue that one of the premises of Arrow's proof, that of the transitivity of indifference, is untenable. Several concepts of preference are introduced and counter-instances are offered to the transitivity of indifference defined along the standard lines in terms of these concepts. Alternate analyses of indifference in terms of preference are considered, and it is shown that these do not serve Arrow's purposes either. (...) Finally, it is argued that in the single special case in which indifference could plausibly be held to be transitive, Arrow's thesis is innocuous. (shrink)

Since its publication in 1965, Brian Barry's seminal work has occupied an important role in the revival of Anglo-American political philosophy. A number of ideas and terms in it have become part of the standard vocabulary, such as the distinction between "ideal-regarding" and "want-regarding" principles and the division of principles into aggregative and distributive. The book provided the first precise analysis of the concept of political values having trade-off relations and its analysis of the notion of the public interest has (...) also been significant.

The central purpose of this paper is to sketch the logic of being a democrat. That is, what is involved in being a democrat will be defined and delineated. I shall proceed by first examining Richard Wollheim's alleged paradox of democratic theory. Wollheim's solution to the paradox will then be shown to be unsatisfactory. Next, the concept of being a democrat will be clarified. The stage will then be set for showing that Wollheim's alleged paradox of democratic theory dissolves upon (...) discerning what a democrat qua democrat is committed to believe. In the process of clarifying what is involved in being a democrat and dissolving the alleged paradox of democratic theory, it will become evident that one popular argument often levelled against resistance to democratic law is without foundation. This is the argument that any democrat who conscientiously disobeys valid democratic law is necessarily behaving inconsistently with his democratic principles; and, therefore, if someone does conscientiously disobey valid democratic law, it proves he is not ‘really’ a democrat after all.

A new possible world semantics for deontic logic is proposed. Its intuitive basis is that prohibitive predicates (such as "wrong" and "prohibited") have the property of negativity, i.e. that what is worse than something wrong is itself wrong. The logic of prohibitive predicates is built on this property and on preference logic. Prescriptive predicates are defined in terms of prohibitive predicates, according to the wellknown formula "ought" = "wrong that not". In this preference-based deontic logic (PDL), those theorems that give (...) rise to the paradoxes of standard deontic logic (SDL) are not obtained. (E.g., O(p & q) → Op & Oq and Op → O(p v q)) are theorems of SDL but not of PDL.) The more plausible theorems of SDL, however, can be derived in PDL. (shrink)

A possible world semantics for preference is developed. The remainder operator () is used to give precision to the notion that two states of the world are as similar as possible, given a specified difference between them. A general structure is introduced for preference relations between states of affairs, and three types of such preference relations are defined. It is argued that one of them, actual preference, corresponds closely to the concept of preference in informal discourse. Its logical properties are (...) studied and shown to be plausible. (shrink)

Giving ‘facts’ and ‘truth’ their ordinary senses, can one resist equating truth with correspondence to fact? For, with every variation in facts, there would necessarily be a corresponding variation in what propositions were true. But there would likewise be a corresponding variation in which they were false. Moreover, for any true proposition, the Correspondence Theory is committed also to denying that the existence of the fact believed normally follows just from the existence of the belief.
