Recombinant DNA technology will soon allow physicians an opportunity to carry out both somatic cell- and Germ-Line gene therapy. While somatic cell gene therapy raises no new ethical problems, gene therapy of gametes, fertilized eggs or early embryos does raise several novel concerns. The first issue discussed here relates to making a distinction between negative and positive eugenics; the second issue deals with the evolutionary consequences of lost genetic diversity. In distinguishing between positive and negative eugenics, the concept of malady (...) is applied as a definitional criterion for identifying genetic disorders that could qualify for Germ-Line therapy. Because gene replacement techniques are currently unavailable for humans, and because even if they were possible the number of people involved would be quite small, the loss of diversity concern seems moot. Finally, we dissuss the issue of iatrogenic disorders associated with gene therapy and discuss several ‘real world considerations.’. (shrink)

Electroencephalography-neurofeedback has become a valuable tool in the field of psychology, e.g., to improve cognitive function. Nevertheless, a large percentage of NF users seem to be unable to control their own brain activation. Therefore, the aim of this study was to examine whether a different kind of visual feedback could positively influence NF performance after one training session. Virtual reality seems to have beneficial training effects and has already been reported to increase motivational training aspects. In the present study, we (...) tested 61 young healthy adults to investigate, whether 3D VR-based NF training has a more beneficial effect on the sensorimotor rhythm power increase than a mere 2D conventional NF paradigm. In the 3D group, participants had to roll a ball along a predefined path in an immersive virtual environment, whereas the 2D group had to increase the height of a bar. Both paradigms were presented using VR goggles. Participants completed one baseline and six feedback runs with 3 min each, in which they should try to increase SMR power over Cz. Half of the participants received real feedback whereas the other half received sham feedback. Participants receiving 3D VR-based feedback showed a linear increase in SMR power over the feedback runs within one training session. This was the case for the real as well as for the sham 3D feedback group and might be related to more general VR-related effects. The 2D group receiving the conventional bar feedback showed no changes in SMR power over the feedback runs. The present study underlines that the visual feedback modality has differential effects on the NF training performance and that 3D VR-based feedback has advantages over conventional 2D feedback.

Rationale: Deep brain stimulation (DBS) of the hippocampus is proposed for enhancement of memory impaired by injury or disease. Many pre-clinical DBS paradigms can be addressed in epilepsy patients undergoing intracranial monitoring for seizure localization, since they already have electrodes implanted in brain areas of interest. Even though epilepsy is usually not a memory disorder targeted by DBS, the studies can nevertheless model other memory-impacting disorders, such as Traumatic Brain Injury (TBI). Methods: Human patients undergoing Phase II invasive monitoring for (...) intractable epilepsy were implanted with depth electrodes capable of recording neurophysiological signals. Subjects performed a delayed-match-to-sample (DMS) memory task while hippocampal ensembles from CA1 and CA3 cell layers were recorded to estimate a multi-input, multi-output (MIMO) model of CA3-to-CA1 neural encoding and a memory decoding model (MDM) to decode memory information from CA3 and CA1 neuronal signals. After model estimation, subjects again performed the DMS task while either MIMO-based or MDM-based patterned stimulation was delivered to CA1 electrode sites during the encoding phase of the DMS trials. Each subject was sorted (post hoc) by prior experience of repeated and/or mild-to-moderate brain injury (RMBI), TBI, or no history (control) and scored for percentage successful delayed recognition (DR) recall on stimulated vs. non-stimulated DMS trials. The subject’s medical history was unknown to the experimenters until after individual subject memory retention results were scored. Results: When examined compared to control subjects, both TBI and RMBI subjects showed increased memory retention in response to both MIMO and MDM-based hippocampal stimulation. Furthermore, effects of stimulation were also greater in subjects who were evaluated as having pre-existing mild-to-moderate memory impairment. Conclusion: These results show that hippocampal stimulation for memory facilitation was more beneficial for subjects who had previously suffered a brain injury (other than epilepsy), compared to control (epilepsy) subjects who had not suffered a brain injury. This study demonstrates that the epilepsy/intracranial recording model can be extended to test the ability of DBS to restore memory function in subjects who previously suffered a brain injury other than epilepsy, and support further investigation into the beneficial effect of DBS in TBI patients.

Background Regulations on research ethics in France have evolved considerably over the past four years: the implementation of the Jardé law and of the General Data Protection Regulations have changed the landscape of research ethics for research involving or not involving human persons. In a context of creation of an Institutional Review Board at the University of Bordeaux, France, we sought to explore research ethics practices and perceptions in the medical community of our University Hospital. Methods A short questionnaire was (...) sent to all physicians of the University Hospital of Bordeaux. The questionnaire included closed questions and main topics were: physicians’ education in research ethics, ethics practices concerning researches non implying human persons, and physicians’ perceptions about current regulations. Results 86 questionnaires were sent back. If a majority of physicians have validated Good Clinical Practices trainings, there was a low rate of specific training on fundamental references in research ethics and a high proportion of responders do not consider themselves as educated in research ethics after completion of GCPs. Regulations on research ethics have many implications on medical research, especially by inducing changes in protocols in order to alleviate ethical requirements. Malpractices were acknowledged like false mention of positive opinion from an ethics committee. If If a majority of responders considers regulations as a positive answer to research ethics, a large majority considers it as a constraint and a complexification of research process. For 58%, regulations in research ethics are perceived as a hindrance for research initiatives. Conclusion Because of their impact on research process, regulations seem to constitute a scarecrow for physicians. Lack of training, bad representations and questionable practices highlight the need to improve education and to propose concrete guidance for medical researchers. (shrink)

The author presents and defends three theses: (1) "the first is that it is not profitable for us at present to do moral philosophy; that should be laid aside at any rate until we have an adequate philosophy of psychology." (2) "the second is that the concepts of obligation, And duty... And of what is morally right and wrong, And of the moral sense of 'ought', Ought to be jettisoned if this is psychologically possible...."

With increased visibility of trans people comes increased philosophical interest in gendered language. This chapter aims to look at the research on gendered language in analytic philosophy of language so far, which has focused on two concerns: (1) determining how to define gender terms like ‘man’ and ‘woman’ such that they are trans inclusive and (2) if, or to what extent, we should use gendered language at all. We argue that the literature has focused too heavily on how gendered language (...) can harm trans people, and has not considered how trans people use gendered language to create meaning and joy for ourselves. Pulling from the literature in sociolinguistics, we look at examples of how trans people use language to make their lives better by gaining recognition, playing with gendered language, finding joy in gendered language, and taking control of definitional power, concluding that debates about gendered language need to consider not only how such language harms trans people but also how trans people use it for our own liberation.

As a preliminary step to beginning to assess the usefulness of clinical vignettes to measure ethical sensitivity in undergraduate medical students, five clinical vignettes with seven to nine ethical issues each were created. The ethical issues in the vignettes were discussed and outlined by an expert panel. One randomly selected vignette was presented to first, second and third year students at the University of Toronto as part of another examination. The students were asked to list the issues presented by the (...) patient problem. Responses from 281 students were obtained. These students identified an average of 2.72 ethical issues per vignette. Each response was classified under the domains of autonomy, beneficence and justice. Comparisons were made between classes and between vignettes. There was considerable variation between classes and the responses to different vignettes seem to indicate that different vignettes measure the various domains in different ways. It does appear that the use of vignettes is one way to measure aspects of ethical sensitivity in medical students but more study is required to clarify exactly what is being measured. (shrink)

An instrument to assess 'ethical sensitivity' has been developed. The instrument presents four clinical vignettes and the respondent is asked to list the ethical issues related to each vignette. The responses are classified, post hoc, into the domains of autonomy, beneficence and justice. This instrument was used in 1990 to assess the ethical sensitivity of students in all four medical classes at the University of Toronto. Ethical sensitivity, as measured by this instrument, is not related to age or grade-point average. (...) Sensitivity increases between the 1st and 2nd year and then decreases throughout the rest of undergraduate medical training, such that the 4th-year students identify fewer issues than those entering medical school. Students expressing a career choice of family medicine identify more issues than their peers. Several problems with the use of the instrument and the interpretation of the data were found. Nonetheless, these findings, if reproducible, are important and their meaning needs further discussion. (shrink)

Over the past few years, over a dozen states have proposed, and almost as many have passed, something referred to as the Pain-Capable Unborn Child Protection Act, a piece of legislation that makes abortion impermissible once fetal pain is possible and that further stipulates the fetus can feel pain at or before 20 weeks of gestation. Some very important questions immediately relevant to the abortion debate, perhaps even to the more complex issue of fetal rights, are raised by this legislation, (...) especially because it would impinge on the second-trimester abortion rights guaranteed by Roe. We first inquire whether the claim of fetal pain perception at or before 20 weeks is true and how such a claim should be substantiated. Next, we inquire whether the fetal capacity to experience pain, at whatever stage of development, reflects on the morality of abortion and whether it should be at all relevant to determining its legality. Finally, we would like to explore the implications that a commitment to a pain-related or sentience criterion of rights might have for a pro-life agenda. (shrink)

There is a curious phenomenon where people from marginalized populations are taken to be arrogant when they show no signs of superiority. In effect, their actions are misconstrued, and their attitudes are rendered unintelligible. Given that arrogance is standardly taken to be a flaw in one’s moral character, understanding such misattributions should give us insight into the affective marginalization many people face. This talk aims to give a thorough exploration of arrogance under oppression. I argue that arrogance is a kind (...) of self-preoccupation that involves projecting one’s values, goals, and concerns onto others as if they were objective values, goals, and concerns. When the affectively marginalized communicate their self-respect through things like protest, people mistake that self-respect as self-preoccupation given how the affectively marginalized are constructed. Furthermore, given how affective marginalization not only inhibits how the marginalized are understood by others, but inhibits their own affective lives, I argue that taking up an arrogant attitude is not always morally vicious, but can be a beautiful form of political resistance but all things considered good.

Philosophers of race and other writers in the Black and Latinx intellectual traditions have remarked on what it is like to live under “the racial gaze,” to be shaped and limited by the way whites perceive us. However, little work has been spent developing how the racial gaze functions in whites’, and other racially privileged people’s, moral psychology. I argue in this paper that there is a morally objectionable way of perceiving people of color. This claim builds on an insight (...) from Iris Murdoch that our perception can be morally evaluable and extends it to issues of race. I articulate how racial stereotypes and misvaluing distort one’s perception of people of color and that these distortions are organizing around a dominant conception for race that plays an important role in the oppression of people of color. I believe understanding racist perception lays a foundation for understanding the moral dimensions of interpersonal (as opposed to structural) racism. (shrink)

Given the tremendous burst of activity in the philosophy of science during the last quarter century, the number of books by trained philosophers dealing with the logic of biology is surprisingly small. Simon’s book resembles Morton Beckner’s The Biological Way of Thought in its comprehensive ambitions: "trying to discover what, if anything, is distinctive about biological science, its concepts, and its mode of explaining." The most obvious difference of the two books is Simon’s long central chapter on "Theories, Models, and (...) the Concept of the Gene," which deals with the history of genetics from Mendel’s predecessors to the successors of Watson and Crick. Beckner paid little explicit attention to the history of biology. Another difference lies in Beckner’s dogged assessment of all problems in the logic of biology from the perspective of what he called the Humean Pattern of Explanation—a detailed and difficult variant of the approach of Hempel, Oppenheim, and Nagel. Simon’s philosophical position is more flexible than Beckner’s. He provides an acceptable review of the literature of the last decade and a half; some of his conclusions are most interesting—even when incompletely supported by his arguments; and the utility of his book is insured by the fact that it is necessary to go back over twelve years to find another with which it can be compared. The first chapter contains a very effective critique of J. J. C. Smart’s thesis that biology is no more an autonomous science than is electrical engineering, but is merely applied physics and chemistry. Smart had argued from the grounds that all biological generalizations implicitly refer to terrestrial evolution and are not truly universal, and Simon demonstrates the general lack of success of all efforts to demonstrate a difference in kind between so-called laws of nature and empirical generalizations of the sort found in biology. The second chapter continues in this same vein, drawing an interesting contrast between phylogenetic explanation in biology and the explanation of individual events in human history, and claiming that ‘explanatory’ status may be granted to accounts which do not meet the requirements of the deductive-nomological model, as in the case of Darwin’s theories of the geographical distribution of plants and animals and the persistence of rudimentary organs. The author’s negative reaction to much of the recent philosophical literature concerning the role of functional analysis in biology seems particularly well placed. Following Hempel, most philosophers writing in the past ten years have regarded the occurrence of the item whose function is in question as the event to be explained. Simon correctly points out that in the biological literature, statements indicating the presence of this item are part of the explanans, usually one component in an explanation of the normal functioning of the organism. He also insists that functional or teleological statements cannot effectively be replaced by nonteleological ones. A functional account is one that relates an entity to the role it plays in an organized system. In the first of several serene non-sequiturs which mar the latter half of this book, Simon insists that the above account shows that the notion of function is essentially an "extrinsic" one and that teleological principles generally cannot be used to account for experience. No better argument than an appeal to Kant’s authority backs up this conclusion. The third chapter deals with the recent history of genetics; its summary makes the claim that "at no time during this history was it correct to say that one model was replaced by another one; rather, the development appears to have been one involving successive correction and refining of earlier conceptions. There has been no revolution: geneticists have always succeeded in either repelling or accommodating critical attacks on the model." The evidence presented earlier in the chapter confers some plausibility on this conclusion, but no more: Simon takes no notice of the controversy surrounding Kuhn and the notion of scientific revolutions, and provides no criteria by which to distinguish "revolutions" from "accommodations." The precise nature of the methodological continuity to be found in the history of genetics is crucial for the view that "biology, or at least genetics, must be regarded as incapable of yielding a complete explanation of the phenomena that come within its purview; if the ultimate principles appealed to are not those of chemistry and physics and hence essentially nonbiological, the explanation cannot be regarded as complete." The text does not clearly indicate the extent to which the author agrees with the statement just quoted; perhaps he only attributes it to "many biologists" impressed by the successes of molecular genetics. It is clear the Simon regards something he calls the "Cartesian attitude" as pervasive in biology. "Biologists are committed to attempting to explain the phenomena of life in terms of the nonliving... The property of being alive or being associated with a living system is simply not treated as a logical primitive within biological science." But this seems to take us back full circle—to the position of Smart, that biology is no more than applied physics and chemistry. Simon disagrees with Smart. How does he stand vis-a-vis this last statement of the Cartesian spirit he finds so pervasive in biology? I think he disagrees with it, but it is very hard to tell. Perhaps the answer is that the resolution of the issue of the autonomy of biology is a pragmatic matter, relative to a complex set of needs and commitments: the sorts of things that determine life styles, political attitudes, and religious points of view, as well as the growth of scientific understanding. The question of the precise configuration of Simon’s pragmatism remains very vague indeed—a consequence of his over use of the style of impersonal attribution rather than direct assertion. Simon says generally sane and familiar things about Biology and the Idea of Progress and about Biology and Ethics. The really startling assertion of the penultimate chapter, that "consciousness" is neither a biological nor a behavioral predicate, and that its foundations are essentially moral and legal, is unfortunately supported by no argument whatsoever. Instead, the reader is urged to examine two of the author’s previous articles.—E. M. (shrink)

Is God's foreknowledge compatible with human freedom? One of the most attractive attempts to reconcile the two is the Ockhamistic view, which subscribes not only to human freedom and divine omniscience, but retains our most fundamental intuitions concerning God and time: that the past is immutable, that God exists and acts in time, and that there is no backward causation. In order to achieve all that, Ockhamists distinguish ‘hard facts’ about the past which cannot possibly be altered from ‘soft facts’ (...) about the past which are alterable, and argue that God's prior beliefs about human actions are soft facts about the past.

Two experiments examine the effects of unreportable hints on anagram solving performance and on solvers' subjective experience of insight. In Experiment 1, after seeing a hint presented too briefly to identify, participants solved anagrams preceded by the solution fastest and solved anagrams preceded by unrelated hints slowest. Participants' “warmth” ratings for solution hints were more insight-like than those for unrelated hints. In Experiment 2 a hint, or no hint, was presented at one of three different exposure durations . Participants benefited (...) from solution-relevant hints that were either unreportable or reportable, but showed a cost only for unrelated hints that were reportable. Participants' ratings of their insight experiences showed that unreportable solution and semantically related hints produced more insight-like experiences than did unrelated hints. The results suggest that unreportable processing of solution-related information is important for the insight experience. (shrink)
