Devant le constat du déclin toujours plus rapide de la diversité biologique et les limites des res- sources disponibles pour l’enrayer, il est nécessaire de déterminer quels moyens devraient être engagés dans sa protection. Pour ce faire, une méthode efficace serait d’évaluer les bénéfices tirés de la biodiversité afin d’estimer rationnellement les coûts légitimes de sa protection. L’évaluation économique, qui se présente d’emblée sur un mode quantitatif, serait alors un outil précieux. Dans ce texte, nous présentons différentes méthodes d’évaluation économique (...) de la biodiversité ainsi que certaines de leurs limites méthodologiques. Par la suite, nous montrons qu’en dépit de ses avantages pratiques, l’évaluation économique échoue à représenter l’ensemble des valeurs en jeu dans la protection de la biodiversité. Nous décrivons alors trois types de valeurs incommen- surables avec des bénéfices économiques : la valeur de legs, qui renvoie aux obligations de trans- mission du patrimoine naturel dont nous avons hérité ; la valeur d’existence, qui renvoie à la considération morale d’intérêts autres que ceux des êtres humains ; la valeur de transformation, qui renvoie à la capacité d’examiner et de critiquer nos préférences et inclinaisons afin d’inclure celles-ci dans une vision du monde rationnelle et cohérente. Pour conclure, nous plaidons en faveur de l’élaboration de méthodes de concertation et d’évaluation participatives et pluralistes permettant de rendre compte de la diversité et de l’hétérogénéité des valeurs de la biodiversité.

Despite being increasingly available to us all, retirement pensions remain unequally distributed: between rich and poor, young and old, men and women, and possibly different generations. As this topic receives little attention in moral and political philosophy, the articles in this thesis aim to deliver an original account of justice in retirement pensions along liberal egalitarian lines. The first part defends retirement pensions as a distribution of free time. It shows that including free time in the list of goods that (...) liberal egalitarians prioritise is plausible and avoids problems that would otherwise arise with other candidates, most notably leisure. Retirement as free time is an essential feature of liberal egalitarian societies by (re)distributing the means to pursue any life project, and especially valuable for the poor who work and contribute the longest. The second part makes a case for 'libertirement', a proposal to increase the freedom to enjoy free time across life, as a matter of justice between those who live long and those who die early. Specifically, I propose adding reverse pensions and sabbaticals on top of old-age retirement. Besides showing the importance of longevity for age-group justice, I also draw implications for distributing unconditional basic income and income taxes across life, which I suggest may offer alternative paths to libertirement. Finally, the third part discusses the cases of pension inequality between genders and generations, pushing us to refine our account further. I conclude that there is often a mismatch between liberal egalitarian justice and the design of retirement schemes. The solution is often but not always to reform these systems. Sometimes, we have reasons to revise our very own principles of justice. (shrink)

The aim of this paper is to determine whether the present generation should preserve non-human living things for future generations, even if in the future all the contributions these organisms currently make to human survival in decent conditions were performed by adequate technology and future people's preferences were satisfied by this state of affairs. The paper argues it would be wrong to leave a world without non-human living plants, animals and other organisms to future generations, because such a world would (...) fail to secure one of the conditions of future people’s autonomy, that is, availability of adequate options. Building upon Joseph Raz’s account of autonomy, the paper shows that the presence of non-human living organisms is part of an adequate range of options insofar as, to be adequate, options must meet a test of variety. According to Raz, options pass this test if they enable human agents to exercise a set of physical, affective, imaginative and cognitive capacities humans normally have an innate drive to exercise. The paper discusses empirical findings as well as psychological theories that provide support to the hypothesis that interactions with non-human living organisms enable human beings to develop and exercise these capacities by shaping these capacities in a special way, different from the way interactions with other environments do.

This paper assesses employees’ moral agency within corporate capitalism from a politically liberal standpoint. While political liberalism has spelt out its key institutional implications at state level, it has neglected moral agency at work, assuming that a rights-based state that secures freedom of contract, free choice of occupation and a free labour market within a fair context would protect it sufficiently. Yet two features of corporate capitalism constrain employees’ moral agency: the relation of authority that forms part of the work (...) contract and organisations’ fragmented decision-making processes. Both seem at odds with the liberal ideal of allowing people to live by their own conception of the good. Consequently, this paper examines whether political liberalism should recommend greater safeguards for protecting workers’ moral agency. It proposes a criterion for assessing corporate capitalism: the ‘moral space’ defined as the socially shaped opportunities for action that can be enacted or endorsed from a comprehensive perspective. It argues that liberals should favour arrangements that widen workers’ moral space and suggests institutional designs that may achieve this while remaining within liberal boundaries. (shrink)

Résumé Partant du principe que la philosophie de la connaissance de Poincaré est cohérente, j’essaie de faire voir que son conventionnalisme en géométrie et en physique n’est qu’une conséquence de son intuitionnisme. Après avoir rappelé, dans la première section, ce qu’est l’intuitionnisme et décrit ce que l’intuitionnisme de Poincaré a de spécifique, je montre, dans la deuxième section, comment celui-ci retentit sur la conception de l’espace. Dans la troisième section, j’applique les conclusions précédemment établies à la question très controversée de (...) la découverte de la relativité restreinte en renvoyant dos à dos les historiens : il n’a rien manqué à Poincaré pour découvrir la relativité restreinte, car, cette théorie étant incompatible avec son intuitionnisme, il n’avait aucune raison d’y adhérer.Taking for granted that Poincaré’s epistemology is consistent, I attempt to show that his geometrical and physical conventionalism is no more than a consequence of his intuitionism. After having rehearsed the issues defining intuitionism and describing what is particular to Poincaré’s version in the first section of the paper, I show, in the second section, how Poincaré’s intuitionism influenced his conception of space. In the last section, I apply these now established conclusions to a very contested issue, the discovery of the special theory of relativity. Rejecting the view of historians on both sides of the issue, I argue that Poincaré had everything he would have needed to discover the special theory of relativity, but that since this theory is incompatible with his intuitionism, he had no reason to adopt it.

La présente contribution vise à offrir au lecteur une présentation de la doctrine suffisantiste de la justice, de ses justifications générales et spécifiques et de son articulation possible avec d’autres théories de la justice. Elle explore certains aspects plus particuliers tels que la place de la responsabilité en son sein, son applicabilité au domaine intergénérationnel ou son positionnement par rapport à la question des « vies-complètes ». Elle montre aussi en quoi, quelles que soient les faiblesses possibles de cette doctrine, (...) elle présente des caractéristiques la rendant non redondante, en particulier par rapport à l’égalitarisme du leximin.This paper aims at presenting sufficientarianism, its justifications, specificities and the ways in which it can be combined with other theories of justice. We also explore more specific dimensions such as the place of responsibility-sensitivity, the doctrine’s application to the intergenerational realm or its interest for « complete-life » questions. We show to what extent, despite some weaknesses, it is not redundant when compared to or combined with leximin egalitarianism. (shrink)

Social agreements, roughly put, are a focused and actual variant of social contracts. They are focused on the agreement of parties to co-operate and they pertain to basic aspects of living and living together; however, not comprehensively but focused on a specific theme or themes such as sanitation, water supply or energy provisions. Unlike hypothetical social contracts, social agreements can be empirically studied. So what is their implication for hypothetical social contract, and beyond that for justice and sustainability? This paper (...) introduces social agreement via a case study of social agreement in watershed development in an arid zone with low-income farmers. Watershed development in this context seeks to restore degraded land and simultaneously local democratic institutions. It is an ecological and social investment with medium-term and long-term benefits, i.e. for both present and future generations. Social agreement makes us rethink some issues in the theory and practice of justice and sustainability: how we frame the relation of generations in intergenerational saving, how we think about stability beyond the nation state, and how agreement is a dynamic process that creates the space for the capabilities required to support it in a just and sustainable way. On the global level, social agreement is a possibility for the affluent to discharge their responsibility via investments in such agreements. (shrink)

In this paper, the author offers a synoptic view of different theories of intergenerational justice, along two dimensions (savings/dissavings) and three modalities (prohibition, authorisation, obligation). After presenting successively the indirect reciprocity, the mutual advantage, the utilitarian and the Lockean approaches, special attention is given to the egalitarian theory of intergenerational justice. Two key differences between the egalitarian view on intergenerational justice and the sufficientarian interpretation of sustainability are highlighted.

This paper breaks with the sociological notion of ‘risk society’ and argues in favour of a philosophical view that sees the two planetary threats of late modernity, nuclear weapons and global warming, as ultimate challenges to morality and politics rather than risks that we can take and manage. The paper also raises the question of why we should feel responsible for the effects of these two global challenges on future generations and in this sense elaborates on the transgenerational chain of (...) parenthood rather than on considerations of justice.
