Counterfactuals is David Lewis' forceful presentation of and sustained argument for a particular view about propositions which express contrary to fact conditionals, including his famous defense of realism about possible worlds and his theory of laws of nature.

Philosophically, the most interesting objection to the reliance on advance directives to guide treatment decisions for formerly competent patients is the argument from the loss of personal identity. Starting with a psychological continuity theory of personal identity, the argument concludes that the very conditions that bring an advance directive into play may destroy the conditions necessary for personal identity, and so undercut the authority of the directive. In this article, I concede that if the purpose of a theory of personal (...) identity is to provide an answer to the question What is it for a person to persist over time?, then reflection on personal identity poses a potentially serious threat to the moral authority of advance directives. However, as Marya Schechtman observes, questions about how a single person persists through change are not what most of us are interested in when we think about who a person is. Rather, we are interested in what it means to say that a particular set of actions, experiences, and characteristics is that of a given person rather than someone else. (shrink)

The substituted judgement principle is often recommended as a means of promoting the self-determination of an incompetent individual when proxy decision makers are faced with having to make decisions about health care. This article represents a critical ethical analysis of this decision-making principle and describes practical impediments that serve to undermine its fundamental purpose. These impediments predominantly stem from the informality associated with the application of the substituted judgement principle. It is recommended that the principles upon which decisions are made (...) about health care for another person should be transparent to all those involved in the process. Furthermore, the substituted judgement principle requires greater rigour in its practical application than currently tends to be the case. It may be that this principle should be subsumed as a component of advance directives in order that it fulfils its aim of serving to respect the self-determination of incompetent individuals.

I discuss conditions for the validity of proxy consent to treatment on behalf of an incompetent person. I distinguish those incompetents who, when previously competent, expressed an opinion on the treatment in question from those who were never competent or who, though previously competent, never expressed an opinion on the proposed treatment. In the former case valid proxy consent usually requires respecting the stated wishes of the patient. The latter case is more difficult. I consider a widely-held principle which appeals (...) to the counterfactual wishes of the incompetent person. I argue that it is unacceptable and propose in its place a principle having to do with the best interests of the patient.

Despite clear legislative and judicial support, a well established ethical consensus, and increased efforts at information dissemination and education, proxy decision making for incapacitated patients continues to produce moral muddle and poor resolutions in end-of-life care.In her analysis of the proxy-doctor relationship, Nancy Dubler spells out the institutionalized patterns that keep the promise of proxy directives so often unrealized. Facing medically complex care of an incapacitated patient, health care teams are apt to view the proxy as a potentially indecisive or (...) unrealistically demanding decision-maker, less a stand-in for the patient than an interloper whose improper, misguided, or self-interested decisions will work against the patient's best interests. So perceived, proxies are routinely relegated to the edges of care planning discussions, left relatively uninformed and unconsulted, and then suddenly thrust center stage to face decisions they find overwhelming. Confronting such decisions, proxies need support and compassion. What they often find is isolation and distrust, a web of professional and institutional practices that trammel their efforts to understand and execute their role. (shrink)

In the literature three mechanisms are commonly distinguished to make decisions about the care of incompetent patients: A living will, a substituted judgment by a surrogate (who may or may not hold the power of attorney ), and a best interest judgment. Almost universally, the third mechanism is deemed the worst possible of the three, to be invoked only when the former two are unavailable. In this article, I argue in favor of best interest judgments. The evermore common aversion of (...) best interest judgments entails a risk that health care providers withdraw from the decision-making process, abandoning patients (or their family members) to these most difficult of decisions about life and death. My approach in this article is primarily negative, that is, I criticize the alleged superiority of the living will and substituted judgment. The latter two mechanisms gain their alleged superiority because they are supposedly morally neutral, whereas the best interest judgment entails a value judgment on behalf of the patient. I argue that on closer inspection living wills and substituted judgments are not morally neutral; indeed, they generally rely on best interest judgments, even if those are not made explicit.

Philosophers such as Dan Brock believe that surrogates who make health care decisions on behalf of previously competent patients, in the absence of an advance directive, should make these decisions based upon a substituted judgment principle. Brock favours substituted judgment over a best interests standard. However, Edward Wierenga claims that the substituted judgment principle ought to be abandoned in favour of a best interests standard, because of an inherent problem with the substituted judgment principle. Wierenga's version of the substituted judgment (...) principle and his counterexample to the principle's successful interpretation of valid surrogate consent is presented. A new version of what is meant by the substituted judgment principle is advanced. The new version is not beset with the problems Wierenga initially ascribed to the substituted judgment principle.
