This article described three heuristics that are employed in making judgements under uncertainty: representativeness, which is usually employed when people are asked to judge the probability that an object or event A belongs to class or process B; availability of instances or scenarios, which is often employed when people are asked to assess the frequency of a class or the plausibility of a particular development; and adjustment from an anchor, which is usually employed in numerical prediction when a relevant value (...) is available. These heuristics are highly economical and usually effective, but they lead to systematic and predictable errors. A better understanding of these heuristics and of the biases to which they lead could improve judgements and decisions in situations of uncertainty. (shrink)

The principle of legal paternalism justifies state coercion to protect individuals from self-inflicted harm, or in its extreme version, to guide them, whether they like it or not, toward their own good. Parents can be expected to justify their interference in the lives of their children on the ground that “daddy knows best.” legal paternalism seems to imply that since the state often can know the interests of individual citizens better than the citizens know them themselves, it stands as a (...) permanent guardian of those interests in loco parentis. Put in this blunt way, paternalism seems a preposterous doctrine. If adults are treated as children they will come in time to be like children. Deprived of the right to choose for themselves, they will soon lose the power of rational judgment and decision. Even children, after a certain point, had better not be “treated as children,” else they will never acquire the outlook and capability of responsible adults. (shrink)

Immanuel Kant's Groundwork of the Metaphysics of Morals ranks alongside Plato's Republic and Aristotle's Nicomachean Ethics as one of the most profound and influential works in moral philosophy ever written. In Kant's own words its aim is to search for and establish the supreme principle of morality, the categorical imperative. Kant argues that every human being is an end in himself or herself, never to be used as a means by others, and that moral obligation is an expression of the (...) human capacity for autonomy or self-government. This edition presents the acclaimed translation of the text by Mary Gregor, together with an introduction by Christine M. Korsgaard that examines and explains Kant's argument. (shrink)

This is a new revised version of Dr. Laslett's standard edition of Two Treatises. First published in 1960, and based on an analysis of the whole body of Locke's publications, writings, and papers. The Introduction and text have been revised to incorporate references to recent scholarship since the second edition and the bibliography has been updated.

Psychiatric ethics spans several overlapping domains, including the guidelines for ethical research in psychiatry, the professional ethics required in the practice of psychiatry, and a broader set of moral and ethical problems and dilemmas distinctive to, or at least magnified by, the mental health care setting. Reviewed here are selected issues arising in the last two domains, some seemingly inevitable components of mental disorder and its cultural history and others resultant from recent changes and discoveries. Even as science explains and (...) demystifies mental disorder, it is concluded, new ethical problems will continue to arise in psychiatry and certain recalcitrant problems will likely persist.

In celebration of the fortieth anniversary of the publication of Beauchamp and Childress’s Principles of Biomedical Ethics, a review is undertaken to compare the lists of principles in various bioethical theories to determine the extent to which the various lists can be reconciled. Included are the single principle theories of utilitarianism, libertarianism, Hippocratism, and the theories of Pellegrino, Engelhardt, The Belmont Report, Beauchamp and Childress, Ross, Veatch, and Gert. We find theories all offering lists of principles numbering from one to (...) ten. Many of the differences can be reconciled, but some critical differences remain. (shrink)
