Rawls versus utilitarianism: the subset objection

This paper presents an objection to John Rawls’s use of the original position method to argue against implementing utilitarian rules. The use of this method is pointless because a small subset of the premises Rawls relies on can be used to infer the same conclusion

Multiple View Image Rectification

International audienceThis paper presents an extension of image rectification methods for an arbitrary number of views with aligned camera center. This technique can be used for stereoscopic rendering to enhance the perception comfort or for depth from stereo. In this paper, we first expose that epipolar geometry is not suited to solve this problem. Then we propose a non linear method that includes all the images in the rectification process. Our method only requires point correspondences between the views and can handle images with different resolutions. The tests show that the method is robust to noise and and to sparse point correspondences among the view

A Kantian Critique Of The Care Tradition: Family Law And Systemic Justice

Liberal theories of justice have been rightly criticized for two things by care theorists. First, they have failed to deal with private care relations’ inherent dependency, asymmetry and particularity. Second, they have been shown unable properly to address the asymmetry and dependency constitutive of care workers’ and care-receivers’ systemic conditions. I apply Kant’s theory of right to show that current care theories unfortunately reproduce similar problems because they also argue on the assumption that good care requires only virtuous private individuals. Giving up this assumption enables us to solve the problems regarding both private care relations and systemic injustice

Generalized Blockmodeling of Multi-Valued Networks

This research presents an extension to generalized blockmodeling where there are more than two types of objects to be clustered based on valued network data. We use the ideas in homogeneity blockmodeling to develop an optimization model to perform the clustering of the objects and the resulting partitioning of the ties so as to minimize the inconsistency of an empirical block with an ideal block. The ideal block types used in this modeling are null (all zeros), complete (all ones) and valued. Two case studies are presented: the Southern Women dataset and a larger example using a subset of the IMDb movie dataset

The demandingness of Nozick’s ‘Lockean’ proviso

Interpreters of Robert Nozick’s political philosophy fall into two broad groups concerning his application of the ‘Lockean proviso’. Some read his argument in an undemanding way: individual instances of ownership which make people worse off than they would have been in a world without any ownership are unjust. Others read the argument in a demanding way: individual instances of ownership which make people worse off than they would have been in a world without that particular ownership are unjust. While I argue that the former reading is correct as an interpretive matter, I suggest that this reading is nonetheless highly demanding. In particular, I argue that it is demanding when it is expanded to include the protection of nonhuman animals; if such beings are right bearers, as more and more academics are beginning to suggest, then there is no nonarbitrary reason to exclude them from the protection of the proviso

Personal Identity and Practical Reason: The Failure of Kantian Replies to Parfit

ABSTRACT: This essay examines and criticizes a set of Kantian objections to Parfit's attempt in Reasons and Persons to connect his theory of personal identity to practical rationality and moral philosophy. Several of Parfit's critics have tried to sever the link he forges between his metaphysical and practical conclusions by invoking the Kantian thought that even if we accept his metaphysical theory of personal identity, we still have good practical grounds for rejecting that theory when deliberating about what to do. The argument between Parfit and his opponents illuminates broader questions about the relationship between our metaphysical beliefs and ourpractical reasons.RÉSUMÉ: Cet article examine et critique un ensemble d'objections kantiennes à la tentative de Parfit, dans Reasons and Persons, d'ajuster sa théorie de l'identité personnelle à la rationalité pratique et à la philosophie morale. Plusieurs des critiques de Parfit ont essayé de rompre le lien qu'il tisse entre ses conclusions métaphysiques et pratiques en évoquant l'idée kantienne selon -laquelle, même si nous acceptons sa théorie métaphysique de l'identité personnelle, il existe cependant de bonnes raisons pratiques de rejeter cette théorie lorsque nous délibérons à propos de ce que nous devons faire. Le débat entre Parfit et ses adversaires nous éclaire sur un questionnement plus large à propos du rapport entre croyance métaphysique et raison pratique

Your money or your life: Comparing judgements in trolley problems involving economic and emotional Harms, injury and death: Natalie gold et al

There is a long-standing debate in philosophy about whether it is morally permissible to harm one person in order to prevent a greater harm to others and, if not, what is the moral principle underlying the prohibition. Hypothetical moral dilemmas are used in order to probe moral intuitions. Philosophers use them to achieve a reflective equilibrium between intuitions and principles, psychologists to investigate moral decision-making processes. In the dilemmas, the harms that are traded off are almost always deaths. However, the moral principles and psychological processes are supposed to be broader than this, encompassing harms other than death. Further, if the standard pattern of intuitions is preserved in the domain of economic harm, then that would open up the possibility of studying behaviour in trolley problems using the tools of experimental economics. We report the results of two studies designed to test whether the standard patterns of intuitions are preserved when the domain and severity of harm are varied. Our findings show that the difference in moral intuitions between bystander and footbridge scenarios is replicated across different domains and levels of physical and non-physical harm, including economic harms
