Natural Selection and Design: Comments on Michael Ruse's New Book

Is the adaptive complexity of living organisms the result of evolutionary processes alone? or does it give evidence of intentional design? Michael Ruse appears to argue that we can have it either way. As a scientist I find the argument from design unnecessary. Yet it has great appeal to humans, whose behavior is largely intentional and who look for patterns in events and for the intentions that may have produced them.     

Collective Guilt and Collective Guilt Feelings

Can collectives feel guilt with respect to what they have done? It hasbeen claimed that they cannot. Yet in everyday discourse collectives areoften held to feel guilt, criticized because they do not, and so on.Among other things, this paper considers what such so-called collectiveguilt feelings amount to. If collective guilt feelings are sometimesappropriate, it must be the case that collectives can indeed beguilty. The paper begins with an account of what it is for a collectiveto intend to do something and to act in light of that intention.According to this account, and in senses that are explained, there is acollective that intends to do something if and only if the members of agiven population are jointly committed to intend as a body to do thatthing. A related account of collective belief is also presented. It isthen argued that, depending on the circumstances, a group's action canbe free as opposed to coerced, and that the idea that a collective assuch can be guilty of performing a wrongful act makes sense. The ideathat a group might feel guilt may be rejected because it is assumed thatto feel guilt is to experience a ``pang'' or ``twinge'' of guilt –nothing more and nothing less. Presumably, though, there must becognitions and perhaps behavior involved. In addition, the primacy, eventhe necessity, of ``feeling-sensations'' to feeling guilt in theindividual case has been questioned. Without the presumption that it isalready clear what feeling guilt amounts to, three proposals as to thenature of collective guilt feelings are considered. A ``feeling ofpersonal guilt'' is defined as a feeling of guilt over one's own action.It is argued that it is implausible to construe collective guiltfeelings in terms of members' feelings of personal guilt. ``Membershipguilt feelings'' involve a group member's feeling of guilt over what hisor her group has done. It is argued that such feelings are intelligibleif the member is party to the joint commitment that lies at the base ofthe relevant collective intention and action. However, an account ofcollective guilt in terms of membership guilt feelings is found wanting.Finally, a ``plural subject'' account of collective guilt feelings isarticulated, such that they involve a joint commitment to feel guilt asa body. The parties to a joint commitment of the kind in question may asa result find themselves experiencing ``pangs'' of the kind associatedwith personal and membership guilt feelings. Since these pangs, byhypothesis, arise as a result of the joint commitment to feel guilt as abody, they might be thought of as providing a kind of phenomenology forcollective guilt. Be that as it may, it is argued the plural subjectaccount has much to be said for it.

Faith and reason and physician-assisted suicide.

Aquinas's conception of the relationship of faith and reason calls into question the arguments and some of the conclusions advanced in contributions to the debate on physician-assisted suicide by David Thomasma and H. Tristram Engelhardt. An understanding of the nature of theology as based on revelation calls into question Thomasma's theological argument in favor of physician-assisted suicide based on the example of Christ and the martyrs. On the other hand, unaided reason calls into question his assumptions about the nature of death as in some cases a good for the human person. Finally, if Aquinas is right about the relationship of faith and reason, Engelhardt's sharp contrast between "Christian" and "secular" approaches to physician-assisted suicide needs reconsideration, although his conclusions about physician-assisted suicide would find support.     

Weigh(t)ing for Awareness

We wished to learn if weight perception can be extinguished by studying two patients with right hemisphere brain damage. When lifting weights simultaneously, a patient with right frontal damage was not biased in her judgments of which weight was heavier. By contrast, a patient with right parietal damage reported left-sided weights as being lighter than those on the right. Psychophysical power functions revealed that her awareness of increasing weights on the left was dampened compared to the right when lifting weights individually on each side. Strikingly, her awareness of weight changes on the left was completely abolished when she lifted weights in both hands simultaneously. She demonstrated an unusual split in awareness, being motorically aware of and actively engaged with left-sided weights while being unaware of their incremental changes.

Traffic Offences: Planned or Habitual? Using the Theory of Planned Behaviour and habit strength to explain frequency and magnitude of speeding and driving under the influence of alcohol

This study addresses the socio‐cognitive determinants of traffic offences, in particular of speeding and drinking and driving. It has two aims: (1) to test the hypothesis of a direct effect of habits on offences (i.e., independent of intentions) by employing a specific measure of habits (i.e., the SRIH) and (2) to analyse the offences by taking account of three distinct parameters: Frequency, usual magnitude (i.e., the most frequent deviation from the law) and maximal magnitude (i.e., the greatest deviation occasionally adopted) in order to represent more accurately the variability of the offending behaviours. A total of 642 drivers replied to a questionnaire. The results corroborate the idea that intention and habit are distinct and direct determinants of offences. The use of the SRIH dismisses the criticisms made with regard to the measure of past behaviour. The distinction between the three behavioural parameters proves to be relevant, as their determinants are not exactly similar. Finally, attitude and subjective norm had direct effects on the maximal magnitude and/or on the frequency of the offence. The discussion concerns the contribution of this study to the analysis of offences as well as its limitations and addresses the theoretical plausibility of the direct effects of attitude and the subjective norm.     

Does retrieval intentionality really matter? Similarities and differences between involuntary memories and directly and generatively retrieved voluntary memories

Theories of autobiographical memory distinguish between involuntary and voluntary retrieval as a consequence of conscious intention (i.e., wanting to remember). Another distinction can be made between direct and generative retrieval, which reflects the effort involved (i.e., trying to remember). However, it is unclear how intention and effort interacts. For example, involuntary memories and directly retrieved memories have been used interchangeably in the literature to refer to the same phenomenon of effortless, non‐strategic retrieval. More recent theoretical advances suggest that they are separate types of retrieval, one unintentional (involuntary), another intentional and effortless (direct voluntary retrieval), and a third intentional and effortful (generative voluntary retrieval). Whether this also entails differing phenomenological characteristics, such as vividness, rehearsal, or emotional valence, has not been previously investigated. In the current study, participants reported memories in an experimental paradigm designed to elicit voluntary and involuntary memories and rated them on a number of characteristics. If intention affects the retrieval process, then we should expect differences between the characteristics of involuntary and directly retrieved memories. The results imply that retrieval intention seems to differentiate how a memory appears in a person's mind. Furthermore, we argue that these differences in part could result from differences in encoding and consolidation.     

Individual social capital and the implementation of entrepreneurial intentions: The case of Russia

The current research hypothesized that individual social capital facilitates the implementation of one's intention to start a business. The research samples were drawn from a sample of 2061 adult respondents: a sub‐sample of 269 adults who stated their intention to start their own business during the next two years (‘intenders’) and a matching sub‐sample of 270 who said they did not intend to do so (‘non‐intenders’). The study shows that the ‘intenders’ possessed greater individual social capital. These resources had a positive indirect impact (through increased perceived behavioural control and attitude) on their intention to start their own business.     

Effort to reduce postural sway affects both cognitive and motor performances in individuals with Parkinson’s disease

ObjectivesTo assess the effects of voluntarily reducing postural sway on postural control and to determine the attention level needed to do so in healthy adults (n = 16, 65.9 ± 9.7) and persons with PD (n = 25, 65.8 ± 9.5 years). Tasks: quiet and still standing conditions with and without a category task. Cognitive performance, center of pressure (CoP) displacement variability (RMSCoP) and velocity (VCoP) were assessed in the anterior-posterior (AP) and medial-lateral (ML) directions.Controls showed larger RMSCoP (AP) and VCoP (AP and ML) during still versus quiet standing (p < 0.01), while the PD group demonstrated no changes. In the PD group, RMSCoP and VCoP (ML) increased in still standing when performed with the cognitive task (p < 0.05). In both groups, cognitive responses decreased in still standing (p < 0.05).In PD, attempting to reduce postural sway did not affect postural control under single task conditions, however ML CoP variability and velocity did increase as a dual task. In older adults, increased displacement and velocity in both AP and ML directions was observed during single, but not dual task conditions. Therefore standing still might not be an adequate postural strategy as it increases the attentional demand and affects motor performance, putting persons with PD at greater risk for falls.
