Joshua Greene and Peter Singer argue, on the basis of empirical evidence, that deontological moral judgments result from emotional reactions while dispassionate reasoning leads to consequentialist judgments. Given that there are good reasons to doubt these emotionally driven intuitions, they argue that we should reject Kantian ethics. I argue that the evidence does not support the claim that consequentialism is inherently more reason-based or less emotion-based than Kantian ethics. This is partly because the experiments employ a functional definition of ‘deontological’ (...) that is so broad as to include any non-consequentialist theory, including virtue ethics, divine command theory, and even rule-utilitarianism. Thus the experiments failed to capture the reasons behind the judgments. Also, the results of the experiments are partly due to the extensive use of moral dilemmas like the footbridge version of the trolley scenario. The options in these dilemmas involve different levels of moral thinking. The consequ.. (shrink)

Recently, empirically minded philosophers have employed evidence of widespread, fundamental moral disagreement to argue against moral realism. I argue that the empirical evidence does not refute realism because the disagreement is consistent with certain pluralistic versions of moral realism that posit a set of pro tanto normative principles. Others have appealed to pluralism in defense of moral realism but have used pluralism to attack the empirically based approach to ethical theory. Although I argue that the empirical argument against moral realism (...) fails, I defend the approach and suggest better ways that (pluralist) moral realism could be tested empirically. (shrink)

Cognitive neuroenhancement involves the use of medical interventions to improve normal cognitive functioning such as memory, focus, concentration, or willpower. In this paper I give a Kantian argument defending the use of CNE in science, scholarly research, and creative fields. Kant’s universal law formulation of the categorical imperative shows why enhancement is morally wrong in the familiar contexts of sports or competitive games. This argument, however, does not apply to the use of CNE in higher education, scholarly or scientific research, (...) or creative endeavors such as visual art, fiction or poetry, or musical composition. This is because performance in these areas is embedded within practices that differ in morally significant ways from competitive practices. This important difference provides good reason to think that there is nothing morally wrong with the use of CNE in these areas. My approach is not simply to assume a full-fledged Kantian ethical theory and apply it straight away to the enhancement issue but to establish a reflective equilibrium between our moral intuitions, moral principles that support those intuitions, and the nature of the practices involved.

I defend a strong version of the Kantian claim that actions done solely from duty have moral worth by (1) considering pure cases of acting from duty, (2) showing that love and sympathy, unlike a sense of duty, can often lead us to do the wrong thing, (3) carefully distinguishing moral from non-moral virtues, and (4) by distinguishing pathological sympathy from practical sympathy. Not only is acting purely from a sense of duty superior to acting from love and sympathetic feelings, (...) but the cold-heartedness found in Kant’s examples should be thought of as a virtue rather than a vice.

In deriving his moral code, Hobbes does not appeal to any mind-independent good, natural human telos, or innate human sympathies. Instead he assumes a subjectivist theory of value and an egoistic theory of human motivation. Some critics, however, doubt that his laws of nature can be constructed from such scant material. Hobbes ultimately justifies the acceptance of moral laws by the fact that they promote self-preservation. But, as Hobbes himself acknowledges, not everyone prefers survival over natural liberty. In this essay (...) I show that Hobbes can argue that the desire for self-preservation is rationally required by modifying his subjectivist theory of the good to equate what is good for an agent only with the satisfaction of desires (for her own life) that she has at the time that they are satisfied. It is thus irrational to prefer postmortem glory over survival since an agent must be alive for glory to have any value for her. (shrink)

Most of the philosophical work written on environmental issues focuses on notions such as rights, consequences, duties, etc. And most of the theoretical philosophy done in environmental ethics focuses on questions of whether animals, plants, or ecosystems have inherent value or moral standing independently of their usefulness to humans. A character-based approach has been largely neglected (despite a few important works). In this paper, I consider what a plausible environmental virtue ethics would look like. Specifically, I argue (pace Sandler) that (...) it would not require any distinct eco-virtue but would involve merely widening the scope of traditional virtues to include the non-human world. I further argue that a successful environmental virtue ethics would have to be pluralistic (involving more than one virtue) and would require the formulation of prima facie (rather than absolute) v-rules. Finally, borrowing from Naess, I suggest a way that eco-friendly character could be acquired. (shrink)

Empirical evidence indicates that much of human behavior is unconscious and automatic. This has led some philosophers to be skeptical of responsible agency or personhood in the moral sense. I present two arguments defending agency from these skeptical concerns. My first argument, the “margin of error” argument, is that the empirical evidence is consistent with the possibility that our automatic behavior deviates only slightly from what we would do if we were in full conscious control. Responsible agency requires only that (...) our actions more or less express our conscious goals and values. My second argument is a non-realist defense of moral agency. If we are willing to reject metaethical realism about agents, then there may be good reasons why we should retain the concept of agency in our moralizing, even if automaticity undermines the belief that we are really in conscious control of our behavior. We can do this by adopting a “reactive attitudes” approach to moral responsibility. On this view, agency is determined not by actual features of human psychology but by the attitudes and practices that we ought to adopt in response to the actions and motivations of individuals.

Some of the methods for data collection in experimental psychology, as well as many of the inferences from observed behavior or image scanning, are based on the implicit premise that language use can be linked, via the meaning of words, to specific subjective states. Wittgenstein’s well known private language argument (PLA), however, calls into question the legitimacy of such inferences. According to a strong interpretation of PLA, all of the elements of a language must be publicly available. Thus the meaning (...) of words is not fixed by reference to our private experiences, and so data from subjective state claims indicates nothing about our subjective experiences. Application of PLA to psychological studies based on descriptions of the experience of orgasm offers support for the strong version of the conclusion of PLA. We show that PLA has deep implications for data collection methods and inferences in experimental psychology. In particular we critique two contemporary research projects in neuroscience: one studying the ability to remember emotionally loaded words and the other studying experience of attraction. Both of these projects attempt to link subjective experiences and thought processes to particular observable brain states. The research methods appeal to (implicit) inferences from linguistic usage to subjective states. Application of PLA will show that such inferences cannot be made because the meaning of a word is not determined by any subjective state of the speaker. (shrink)
