Kearns and Star have previously recommended that we measure the degree to which a reason supports a conclusion, either about how to act or what to believe, as the conditional probability of the conclusion given the reason. I show how to properly formulate this recommendation to allow for dependencies and conditional dependencies among the considerations being aggregated. This formulation allows us to account for how considerations, which do not themselves favour a specific conclusion, can modify the strength of a reason (...) for that conclusion, and thus to explain the intensifiers and attenuators described by Dancy. The formulation also accounts for the workings of partial undercutters in epistemology. I then show how my account avoids the counterexamples that Brunero levied against probability-based theories of the strengths of reasons. My account supports the theory, suggested by Kearns and Star, that the strengths of reasons are measured by conditional probabilities. If my account is successful, then it will count in favour of the idea that the strengths of reasons are measured on the same scale as are conditional probabilities. (shrink)

Liberal political philosophy emphasizes the benefits of membership in a cultural group and, in the opinion of this challenging book, neglects its harmful, oppressive aspects. Andrew Kernohan argues that an oppressive culture perpetuates inegalitarian social meanings and false assumptions about who is entitled to what. Cultural pollution harms fundamental interests in self-respect and knowledge of the good and is diffuse, insidious, and unnoticed. This cultural pollution is analogous to environmental pollution, and though difficult to detect, is nonetheless just as real. (...) The book's conclusion is that a liberal state committed to the moral equality of persons must accept a strong role in reforming our cultural environment. (shrink)

The philosophical tradition has given rise to many competing moral theories. Virtue ethics encourages the flourishing of the person, theories of justice and rights tell us to act according to principles, and consequentialist theories advise that we seek to bring about good ends. These varied theories highlight the morally relevant features of the problems that we encounter both in everyday personal interactions and on a broader social scale. When used together, they allow us to address moral conflicts by balancing a (...) plurality of reasons in order to reach nuanced ethical decisions. In _Ethical Reasoning: Theory and Application_, Andrew Kernohan guides the reader through the basics of these moral theories, showing their strengths and weaknesses and emphasizing the ways in which competing moral reasons can be collectively employed to guide decision-making. Throughout, the focus is on practical applications and on how each theory can play a role in solving problems and addressing issues. Numerous questions and exercises are provided to encourage active reflection and retention of information. (shrink)

A popular model of normative decision-making under uncertainty suggests choosing the option with the maximum expected moral choice-worthiness, where the choice-worthiness values from each moral theory, which are assumed commensurable, are weighted by credence and combined. This study adds descriptive uncertainty about the non-moral facts of a situation into the model by treating choice-worthiness as a random variable. When agents face greater descriptive uncertainty, the choice-worthiness random variable will have a greater spread and a larger standard deviation. MEC, as a (...) decision rule, is sensitive only to the expected value of the random variable and not to its standard deviation. For example, MEC is insensitive to cases where an option with a large degree of descriptive uncertainty may have a higher probability of being below some threshold of impermissibility than does an option with less dispersion, even though the latter has a higher expected choice-worthiness. When applied to the same situation, similar moral theories will have statistically correlated choice-worthiness values. This correlation affects the dispersion of the credence-weighted sum of the random variables but not its expected value. Thus, MEC is insensitive to aspects of the normative situation to which a good decision-rule should be sensitive. (shrink)

This book explains the basic concepts of environmental ethics and applies them to global environmental problems. The author concisely introduces basic moral theories, discusses how these theories can be extended to consider the non-human world, and examines how environmental ethics interacts with modern society’s economic approach to the environment. Online multiple-choice questions encourage the reader’s active learning.

When there is only one source of pollution, the language of rights is adequate for justifying solutions to pollution problems. However, pollution is often both a public and an accumulative harm. According to Feinberg, an accumulative harm is a harm to some person brought about by the actions of many people when the action of no single person is sufficient, by itself, to cause the harm. For example, although no single car emits enough exhaust to do any harm, the emissions (...) from many cars can accumulate to an unhealthy level. In this paper, I argue that rights, understood in terms of the will theory of Hart and the interest theories of Lyons and Raz, cannot justify protecting people from public, accumulative harms. I conclude that pollution regulation should focus not on protecting people’s rights, but on preventing harm to people’s interests. (shrink)

This book aims to apply recent thinking in philosophy to the age-old problem of the meaning of life, and to do so in a way that is useful to atheists, agnostics, and humanists. The book reorients the search for meaning away from a search for purpose and toward a search for what truly matters, and criticizes our society's prevailing theory of value, the preference satisfaction theory of the economists. It next argues that emotions are our best guides to what matters (...) in life, and shows how emotional judgments about what matters can be true. Finally it discusses how a meaningful life can be lived, describes the role of justice, freedom, identity, and culture in its construction, and compares the meaningful with the happy life. Andrew Kernohan has a Ph.D in philosophy from the University of Toronto and is an Adjunct Professor at Dalhousie University. He is the author of Liberalism, Equality, and Cultural Oppression (Cambridge University Press, 1998) and various articles in professional philosophy journals. (shrink)

From the standpoint of libertarian ideology, capitalism is a form of liberation. In contrast to the slave, whose productive powers are wholly owned by his master, and the serf, whose productive powers are partially owned by his lord, the worker under capitalism is presented as possessing the fullest possible self-ownership. That capitalism fosters self-ownership is a false and stultifying myth. Exposing its errors from within capitalism's own conceptual framework requires a careful analysis of the concept of a person's “ownership” bodh (...) of his or her productive powers and of the means of exercising these productive powers. This analysis will show that, in certain plausible circumstances, the capitalist economic system can make full self-ownership impossible. Since capitalism's supposed nurturing of self-ownership provides one of the major justifications for its moral legitimacy, capitalist ideology has a serious internal inconsistency. (shrink)

In a recent series of papers, Donald Davidson has put forward a challenging and original philosophy of mind which he has called anomalous monism. Anomalous monism has certain similarities to another recent and deservedly popular position: functionalist cognitive psychology. Both functionalism, in its materialist versions, and anomalous monism require token-token psychophysical identities rather than type-type ones. Both deny that psychology can be translated into, or scientifically reduced to, neurophysiology. Both are mentalistic theories, allowing psychology to make use of intentional descriptions (...) in its theorizing. Anomalous monism uses a belief/desire/action psychology; cognitive science makes use of information-bearing states. But these similarities must not be allowed to conceal an essential difference between the two positions. Cognitive psychology claims to be a science, making interesting, lawlike generalizations for the purpose of explaining mental activity. Anomalous monism denies that psychology is a science by denying that psychological laws can be formulated. Davidson has other ideas for psychology connected with his work on meaning and truth. Hence, the title of one of his essays on anomalous monism is “Psychology as Philosophy”. (shrink)

In two passages of A Theory of Justice Rawls suggests that, as a consequence of his egalitarian theory, the natural talents of persons are common property.We see then that the difference principle represents, in effect, an agreement to regard the distribution of natural talents as a common asset and to share in the benefits of this distribution whatever it turns out to be. The two principles are equivalent, as I have remarked, to an undertaking to regard the distribution of natural (...) abilities as a collective asset so that the more fortunate are to benefit only in ways that help those who have lost out.

How can we lead a good life in a world without God? This clear, concise book applies recent thinking in philosophy to the age-old question of what gives meaning to our lives. The prose is simple, the arguments precise, the ideas powerful and thought-provoking. The book deals with many questions: Why does death not destroy the possibility of meaning? In what way is the search for purpose misleading? Why is there not just one thing that is the meaning of life? (...) Why do pleasures and satisfied desires often seem meaningless? What role do our emotions play in discovering that which truly matters? What is the nature of truth? How do our choices and commitments play a part in leading a meaningful life? Is a meaningful life necessarily a happy one? (shrink)

_Business Ethics: An Interactive Introduction_ connects the academic to the practical, extracting the basic elements of rigorous philosophical ethics into a format that can be understood and applied in the business world. Concepts such as utility, duty, and sustainability are given practical value and connected to examples and methods familiar to business people. Classical ethical theories are surveyed, as are modern perspectives on justice, equality, and the environment. Where possible, quantitative examples and methods are used to show that ethics need (...) not be subjective or vague. Kernohan provides an overview of the basic tools of ethical decision-making and shows how each can be used to resolve moral problems in business environments. Readers are then invited to apply those tools by completing a series of online exercises, receiving immediate objective feedback on their success. The book and its accompanying exercises thus work in concert, offering a unique opportunity for interactive self-directed learning. (shrink)

Recent proposals by Taylor, Bennett, Wright and Cohen to identify teleological systems as systems governed by teleological laws and teleological laws as laws of a certain logical form are discussed. Suggested logical forms are treated with both extensional and simple non-extensional models of nomic necessity and shown to generate problematic entailments not derivable from the causal form alone.
