Grapheme-color synesthetes experience color, not physically present, when viewing symbols. Synesthetes cannot remember learning these associations. Must synesthetic percepts be formed during a sensitive period? Can they form later and be consistent? What determines their nature? We tested grapheme-color synesthete, MC2, before, during and after she studied Hindi abroad. We investigated whether novel graphemes elicited synesthetic percepts, changed with familiarity, and/or benefited from phonemic information. MC2 reported color percepts to novel Devanagari and Hebrew graphemes. MC2 monitored these percepts over 6 (...) months in a Hindi-speaking environment. MC2 and synesthete DN, reported synesthetic percepts for Armenian graphemes, or Cyrillic graphemes + phonemes over time. Synesthetes, not controls, reported color percepts for novel graphemes that gained consistency over time. Phonemic information did not enhance consistency. Thus, synesthetes can form and consolidate percepts to novel graphemes as adults. These percepts may depend on pre-existing grapheme-color relationships but they can flexibly shift with familiarity.

Blair, DavidDavid Tribe, in his article, 'On science, good, bad and ugly' (AH, No. 107, Spring 2012), criticises an earlier article by Victor Bien. Bien - rightly in my view - defends present-day science in respect of three areas where science is under attack; the most prominent of these three is anthropogenic global warming (AGW). Tribe claims that, Victor Bien appears to have inflated views on the sagacity, objectivity and probity of scientists, who can be called (...) our new priests. Much as I respected David Tribe for his work in philosophy, I must criticize much of what he says about science in his article. (shrink)
Blair, David What's the best policy to deal with the catastrophe that looms due to global warming? Fundamentally, we must quickly change our sources of energy away from fossil fuels to non-carbon emitting sources - namely nuclear power and the various renewable sources. 'What's nuclear doing in there?' you may respond. 'Isn't the news about nuclear all bad?' But a growing chorus of scientists and thinkers is warning that, not only is nuclear power quite safe, but that to (...) rule it out poses a grave danger. I quote: Renewables like wind and solar and biomass will certainly play roles in a future energy economy, but those energy sources cannot scale up fast enough to deliver cheap and reliable power at the scale the global economy requires. While it may be theoretically possible to stabilise the climate without nuclear power, in the real world there is no credible path to climate stabilisation that does not include a substantial role for nuclear power.

Blair, David Concerning David Tribe's rejoinder to my 'Science works better than that' , it's pleasing to see that there are some points on which we agree. Unfortunately he continues to make a strong and unjustified attack on the scientific community as a whole-essentially on the grounds that, of the conclusions of science that later turned out to be false, virtually all of them were at some time 'believed' by most scientists. In reply, I shall show that (...) it is his underlying framework that needs to be altered-quite radically. He does not understand what the activity of scientists is like-indeed what it has to be like, when faced with the task of extracting knowledge from the real world. (shrink)
In 2014, Colonel M. Shane Riza published an article in this journal arguing that remotely piloted aircraft and robotic weapons threaten the US Air Force’s warrior ethos. Riza has clearly articulated the sentiments of one side of a vibrant debate within our service. This paper presents an alternative view; a view held by some who have experienced these new forms and tools of war, and who have wrestled with their implications first-hand. In this paper, we address some methodological concerns with (...) Riza’s approach and then engage some misunderstandings about RPA’s relationship to military history and to risk. The second part of this paper takes a close look at some of the early Just War thinkers to determine what implications the tradition may have on the warrior ethos. We propose, as an alternative to Riza’s position, a return to an ethos grounded in humility, charity, and a conception of war as a last resort; in short, a return to the Just Warrior Ethos. (shrink)
A Dedekind-finite set is said to be divisible by a natural number n if it can be partitioned into pieces of size n. We study several aspects of this notion, as well as the stronger notion of being partitionable into n pieces of equal size. Among our results are that the divisors of a Dedekind-finite set can consistently be any set of natural numbers, that a Dedekind-finite power of 2 cannot be divisible by 3, and that a Dedekind-finite set can (...) be congruent modulo 3, to all of 0, 1, and 2 simultaneously.

This paper derives a mathematical expression giving the development of the probability of a scientific hypothesis with the number of confirming tests, as determined by Bayes's theorem, in a special case in which all the tests are "independent" of one another. The simple expression obtained shows clearly how the various factors influence the growth of the probability. The result is used to set a numerical lower bound on the probabilities representing the a priori beliefs of humans in generalizations that become (...) accepted. By making a comparison with the predictions of a "logical atomic" model in the case of physical laws, it is argued that humans have significant a priori "knowledge" in a weak sense. (shrink)
The following progress report views language acquisition as primarily the attempt to create processes that connect together in a fruitful way linguistic input and other activity. The representations made of linguistic input are thus those that are optimally effective in mediating such interconnections. An effective Language Acquisition Device should contain mechanisms specific to the task of creating the desired interconnection processes in the linguistic environment in which the language learner finds himself or herself. Analysis of this requirement gives clear indications (...) as to what these mechanisms may be. (shrink)
Youths with disruptive behavior disorders and psychopathic traits showed reduced amygdala responses to fearful expressions under low attentional load but no indications of increased recruitment of regions implicated in top- down attentional control. These findings suggest that the emotional deficit observed in youths with disruptive behavior disorders and psychopathic traits is primary and not secondary to increased top- down attention to nonemotional stimulus features.
This article examines a particular debate between Eamonn Callan and William Galston concerning the need for a civic education which counters the divisive pull of pluralism by uniting the citizenry in patriotic allegiance to a single national identity. The article offers a preliminary understanding of nationalism and patriotism before setting out the terms of the debate. It then critically evaluates the central idea of Callan that one might be under an obligation morally to improve one''s own patriotic inheritance, pointing to (...) the ineliminable tension between the valuation of one''s own patria by its own terms and a detached critical reason. It concludes by suggesting that we are, in advance of our education, members of a particular patria and that any education must be particularistic. Finally, the danger is noted of presuming that, in each case, there is a single, determinate national tradition. (shrink)
The book presents a selection of paper authored by J. Anthony Blair, one of the most important personalities in the field of argumentation studies, “a frontline worker or pioneer”,, and, I’d like to add, a stylist. The book cover 30 years of research, from 1981 to 2011. Twenty papers are grouped under four thematic sections, “Critical Thinking”, “Informal Logic”, “Argumentation Theory”, and “Logic, Dialectic and Rhetoric”. Each section is preceded by an “Introduction” giving its main orientation, and followed by (...) a “Postscript”, presenting the 2012 author’s afterthoughts; all that gives to the book a “novelistic impulse” prompting the reader to further readings and new theoretical developments. This review focuses on three key questions, that is, the evolution of Blair theoretical vision, from the “Relevance–Acceptability–Sufficiency” criteria, which have defined what may be called the “standard Informal Logic theory” the integration of the reasoning, schemes and the dialogue with the Pragma-dialectical theory; the dialogue with rhetoric about the plurality of norms applicable to authentic argumentative discourse.
