Relationships between factors of intelligence and brain volume

The recent explosion of studies aimed at determining the biological basis of intelligence has revealed that cognitive ability has a strong biological substrate. This study expands on this literature by examining the relation between cognitive ability and MRI-measured brain volume and head size in a sample of adult male siblings recruited from the London, Ontario community in Canada. It was found that brain volume correlated with IQ at 0.35 (P<0.01), thus replicating the results of past studies. Corrections for restriction of range and attenuation in both this and past studies suggest that the population value of the brain volume-IQ correlation is closer to 0.50. Head size variables, with one exception, also showed the expected positive correlations with IQ. The results of a vector analysis on factor scores indicated that the more highly g-loaded a test was the more highly it correlated with brain volume (r=0.59, P<0.01). The sum of the data suggested that although brain volume (and to a lesser extent, head size) is predictive of g, fluid ability, and memory, it does not predict crystallized ability. Unexpectedly, the higher the spatial imaging loading of a test, the less its correlation with brain volume (vector correlation=−0.84, P<0.001).     

All on the Same Side: Reflections on the Dialogue Between Science and Religion

The 'war' between religion and science is winding down, creating new opportunities for fruitful dialogue. The foundations of indirect religion-science dialogue, where the perspectives of the two disciplines illuminate some third subject, are not well established. A detailed comparison of the Roman Catholic bishops' dialogues and a similar program within the American Association for the Advancement of Science illustrates the variety in formalscience-religion interactions and reveals much about the promise, achievements, and limitations of different approaches. Success depends in large part on controlling the diversity of the dialogue group, choosing topics carefully, and adopting positive and cooperative attitudes.     

Theology, Science, and Postmodernism: Responding to Stanley Grenz

This article responds to Stanley J. Grenz's Templeton Lecture, “Why Do Theologians Need to Be Scientists?” published in the June 2000 issue of Zygon (Grenz 2000). In the first part I outline my reasons for finding the kind of theological reflections in which Grenz engages worthy of attention by noting my disagreement with the view that a sufficient response to theological issues can be formulated on the basis of an examination of our biological nature. I assert, in that connection, the autonomy of reason as a way of investigating and understanding the world. In the second part I respond directly to Grenz by explaining my disagreement with the postmodern critique of science upon which he relies and his adherence to Christian eschatology as an answer to the conundrums into which, he posits, we are drawn as a result of that critique. I note that I agree with Grenz, however, that the activity of valuing is necessarily a forward‐looking Godlike endeavor that is not derivable from science. In the third part I suggest that we must be open to the investigation of the possible existence of an objective realm of value and that, in any case, rejection of the postmodern critique of science in many cases pro‐vides a sound basis for the disciplined resolution of factual questions that frequently lie at the base of disagreements about values.     

The Enlightenment That Won't Go Away: Modernity's Crux

The Critical Process unleashed by the Enlightenment and endlessly resharpening itself to this day has mortally wounded the God of Deism, maybe also of theism, even of Christianity. A temptation of Christian theology is to retreat in denial into an updated version of Deism, seemingly granting full license to modern science but only so long as it does not impugn God's love. The alternative here proposed is to ride out The Critical Process, in fact to encourage it, all the way into modernity's crux: How can a design that is not benign still be divine? The Christian reply is: through a real death of God and of ourselves as well, and through resurrections beginning now, thus freeing The Critical Process from the illusion of insuring our survival and, instead, for the honest Enlightenment task of merely telling the truth.

Towards a ‘manifesto’ for super‐recognizer research

This article provides a response to five excellent commentaries on our article ‘Super‐recognizers: From the lab to the world and back again’. Specifically, the response summarizes commonalities between these commentaries. Based on this consensus, we propose a flexible framework for the assessment of superior face recognition and outline guiding principles to advance future work in the field.     

“SCIENCE,” “RELIGION,” AND “SCIENCE‐AND‐RELIGION” IN THE LATE OTTOMAN EMPIRE

Many intellectuals wrote texts on the relations between Islam and science in the nineteenth‐century Ottoman Empire. These texts not only addressed the massive social and cultural changes the Empire was going through, but responded to European authors’ claims about the extent to which Islam was compatible with the modern world. Focusing on several texts written in the second half of the nineteenth century by the influential Muslim Ottoman authors Namik Kemal, Ahmed Midhat, and ?emseddin Sami, this article shows the influence of these exigencies on arguments on Islam and science. In order to represent Islam as a respectable religion in harmony with science, these intellectuals defined a “pure Islam” that was a set of basic principles that could be found in the Qur'an. Rather than an embedded way of life, Islam in these texts was an objectified, delimitable entity that could be imagined as having relations with other entities, such as science.     

CHRISTIAN THOUGHT,RACE, BLUMENBACH,AND HISTORICIZING

Terence Keel's Divine Variations: How Christian Thought Became Racial Science attributes the origins of “racial science” to Christian intellectual history. This is a bold and original argument, but it is not without deep difficulties, particularly in the early sections of the book. The concept of “race” is not sufficiently historicized and the treatment of Johann Friedrich Blumenbach needs to be more firmly grounded in the world of eighteenth‐century natural history.     

A NEW METHODOLOGY FOR CHRISTIAN SYSTEMATIC THEOLOGY

Science and religion are the two strongest influences on the conduct of human life, yet their respective truth claims frequently clash. To facilitate better communication between scientists and theologians on these rival truth claims, the author recommends that Christian theologians use the language and current methodology of science as far as possible so as to present the content of Church teaching in an idiom that would be intelligible not only to scientists but to the educated public as well. In this way, the rival truth claims might complement rather than compete with one another. That is, clothed in the language of science, the truth claims of religion would gain in rational coherence and intelligibility. Natural scientists in turn would have conversation partners better able to deal with philosophical and ethical issues arising out of new scientific discoveries.
