Until recently, philosophers tended to be suspicious of the concept of need. Contributors to this volume build on recent work establishing its philosophical importance. David Wiggins, Gillian Brock and John O'Neill propose remedies for some mistakes made in ignoring or marginalising need, for example in need-free theories of rationality or justice. Christopher Rowe, Soran Reader and Sarah Miller highlight insights that emerge when the concept of need is explored through Plato, Aristotle and Kant - and others that emerge when historical (...) work is seen through the lens of need. Jonathan Lowe and Garrett Thomson consider the role need plays in the philosophies of action and mind. Bill Wringe, David Braybrooke and Sabina Alkire debate how our obligations relating to need are best understood and articulated, and how we can best ensure they are fulfilled, exploring for example how talk of need is related to talk of rights, well-being or capability.

In recent years there has been a good deal of discussion of equality’s place in the best account of distribution or distributive justice. One central question has been whether egalitarianism should give way to a principle requiring us to give priority to the worse off. In this article, I shall begin by arguing that the grounding of equality is indeed insecure and that the priority principle appears to have certain advantages over egalitarianism. But I shall then claim that the priority (...) principle itself is ungrounded and that the priority principle should itself give way to a sufficiency principle based — indirectly, via the notion of an impartial spectator — on compassion for those who are badly off.

In this paper I argue that needs are tremendously salient in developing any plausible account of global justice. I begin by sketching a normative thought experiment that models ideal deliberating conditions. I argue that under such conditions we would choose principles of justice that ensure we are well positioned to be able to meet our needs. Indeed, as the experiment aims to show, any plausible account of distributive justice must make space for the special significance of our needs. I go (...) on to offer some empirical support for this view by looking at the important work of Frohlich and Oppenheimer. I then present an account of our basic needs that can meet a number of goals: for instance, it provides a robust theoretical account of basic needs which can enjoy widespread support, and it can also provide an adequate framework for designing policy about needs, and thus help us to discharge our global obligations. I then briefly discuss the relationship between basic needs and human rights, arguing why the basic needs standard is more fundamental than—and required by—the human rights approach. Finally, I tackle a few important sets of objections to my view, especially some objections concerning distributing our responsibilities for meeting needs. (shrink)

Need-claims are ubiquitous within moral and political theory. However, need-based theories are often criticized for being too narrow in scope and too focused on the material preconditions for leading a decent life for grounding a substantial theory of social justice. The aim of this paper is threefold. Firstly, it will investigate the nature and scope of needs by analysing existing conceptualizations of the idea of needs. In so doing, we will get a better understanding of needs, which will help us (...) to carve out the importance and singularity of basic need claims. Secondly, on the basis of the analysis of needs, it will argue for the concept of a fundamental interest in free social agency, which is much better suited than the idea of basic needs actually to ground a theory of social justice, as it highlights the social and institutional conditions for free agency. Thirdly, using the distinction between basic needs and fundamental interests, it will clarify their respective role in and importance for grounding moral principles. Overall, the paper offers a friendly critique of need-based theories, while arguing for a shift of focus to the idea of fundamental interests. (shrink)

Plausibly, when we adopt a probabilistic standpoint any measure Cb of the degree to which evidence e confirms hypothesis h relative to background knowledge b should meet these five desiderata: Cb > 0 when P > P < 0 when P < P; Cb = 0 when P = P. Cb is some function of the values P and P assume on the at most sixteen truth-functional combinations of e and h. If P < P and P = P then (...) Cb ≤ Cb; if P = P and P < P then Cb ≥ Cb. Cb – Cb is fully determined by Cb and Cbe – Cbe; if Cb = 0 then Cb + Cbe = 0. If P = P then Cb = Cb. (shrink)

This paper considers the goals and methods of theoretical sociology. The chief goal of theoretical work is a theory in two parts-postulates and predictions-the key challenge being to minimize the number of postulates and maximize the number and variety of predictions. The paper discusses the distinctive character of the sentences in each part of the theory and, in light of that bipartite structure, the two main activities of theoretical analysis: (i) speculative thinking, whereby the theorist identifies the starting ideas for (...) the postulates; and (ii) formal reasoning, whereby the theorist constructs the postulates and derives predictions from them. To illustrate the features of a theory and the tasks of theoretical analysis, the paper briefly sketches the theory of the distributive-justice force. (shrink)

This paper considers the question ‘How should institutions enable people to meet their needs in situations where there is no guarantee that all needs can be met?’ After considering and rejecting several simple principles for meeting needs, it suggests a new effectiveness principle that 1) gives greater weight to the needs of the less well off and 2) gives weight to enabling a greater number of people to meet their needs. The effectiveness principle has some advantage over the main competitors (...) including a principle suggested by David Miller in Principles of Social Justice. Miller argues that his principle accounts for the existing data on individuals’ intuitions about meeting needs. The effectiveness principle better accounts for this data. Furthermore, this paper presents a new experiment on intuitions about meeting need that is consistent with the effectiveness principle but not Miller’s principle. (shrink)

In their 1983 article, Popper and Miller present an argument against inductive probability. This argument is criticized by Redhead in his 1985 article. The aim of the present note is to state one form of the Popper-Miller argument, and defend it against Redhead's criticisms.

In two experiments, participants had to choose between a sure and a risky option. The sure option was presented either in a gain or a loss frame. Need was defined as a minimum score the participants had to reach. Moreover, choices were made under two different time constraints and with three different levels of induced need to be reached within a fixed number of trials. The two experiments differed with respect to the specific amounts to win and the need levels. (...) The $$2 \times 2 \times 3$$2×2×3 design was a within-subject design. Data were evaluated on an overall and on a group level, the latter based on participants’ stated risk preference and on revealed preferences using cluster analysis across subjects. Overall, the results showed riskier behavior when the choice options were presented as losses as compared to gains and when the induced need was highest. Time limits enhanced the framing effect.

This book presents an entirely new answer to the question: “What is fair?” In their radical approach to ethics, Frohlich and Oppenheimer argue that much of the empirical methodology of the natural sciences should be applied to the ethical questions of fairness and justice.

Need considerations play an important role in empirically informed theories of distributive justice. We propose a concept of need-based justice that is related to social participation and provide an ethical measurement of need-based justice. The β-ε-index satisfies the need-principle, monotonicity, sensitivity, transfer and several »technical« axioms. A numerical example is given.

Verteilungsgerechtigkeit befasst sich mit der Verteilung von Gütern innerhalb einer Gruppe, wobei verschiedene Verteilungsprinzipien und -ergebnisse als mögliche Ideale einer solchen Verteilung verhandelt werden. Diese normativen Ansätze sind oft rein verbal formuliert, wodurch ihre Anwendung auf unterschiedliche konkrete Verteilungssituationen, die hinsichtlich ihrer Gerechtigkeit beurteilt werden sollen, häufig schwer fällt. Eine Möglichkeit, fein abgestufte Gerechtigkeitsbeurteilungen verschiedener Verteilungen präzise erfassen zu können, besteht in der formalen Modellierung solcher Ideale durch Maße oder Indizes. Die Auswahl eines geeigneten Maßes, das ein gewisses Ideal abbilden (...) soll, muss ihrerseits eine Fundierung erfahren, was durch die Forderung von begründeten Axiomen erreicht werden kann, denen ein Maß genügen soll. In der vorliegenden Arbeit werden solche Axiome für Maße der Verteilungsgerechtigkeit am Beispiel von Bedarfsgerechtigkeit eingeführt. Ferner werden exemplarische Maße der Bedarfsgerechtigkeit vorgestellt. Damit wird für die Beurteilung und Modellierung von Maßen der Verteilungsgerechtigkeit eine erste diskutable Grundlage gelegt.

Distributive justice deals with allocations of goods and bads within a group. Different principles and results of distributions are seen as possible ideals. Often those normative approaches are solely framed verbally, which complicates the application to different concrete distribution situations that are supposed to be evaluated in regard to justice. One possibility in order to frame this precisely and to allow for a fine-grained evaluation of justice lies in formal modelling of these ideals by metrics. Choosing a metric that is (...) supposed to map a certain ideal has to be justified. Such justification might be given by demanding specific substantiated axioms, which have to be met by a metric. This paper introduces such axioms for metrics of distributive justice shown by the example of needs-based justice. Furthermore, some exemplary metrics of needs-based justice and a three dimensional method for visualisation of non-comparative justice axioms or evaluations are presented. Therewith, a base worth discussing for the evaluation and modelling of metrics of distributive justice is given. (shrink)
