When a plant root is reoriented within the gravity field, it responds by initiating a curvature which eventually results in vertical growth. Gravity sensing occurs primarily in the root tip. It may involve amyloplast sedimentation in the columella cells of the root cap, or the detection of forces exerted by the mass of the protoplast on opposite sides of its cell wall. Gravisensing activates a signal transduction cascade which results in the asymmetric redistribution of auxin and apoplastic Ca2+ across the (...) root tip, with accumulation at the bottom side. The resulting lateral asymmetry in Ca2+ and auxin concentration is probably transmitted to the elongation zone where differential cellular elongation occurs until the tip resumes vertical growth. The Cholodny‐Went theory proposes that gravity‐induced auxin redistribution across a gravistimulated plant organ is responsible for the gravitropic response. However, recent data indicate that the gravity‐induced reorientation is more complex, involving both auxin gradient‐dependent and auxin gradient‐independent events. (shrink)

One of the lesser known features of Bernard Lonergan’s Insight is his theory of the relationship between being and goodness. Central to that theory is his claimthat the totality of being is good. From this central claim, Lonergan worked out an “ontology of the good,” in which the structures of ontological interdependencyare reflected in a theory of the scale of higher and lower values. Unfortunately, Lonergan’s way of supporting his claim in Insight is problematic. This article firstsummarizes Lonergan’s theory of (...) the goodness of being, then identifies problems with his exposition, and finally shows how Lonergan could have arrived at thesame positions by closer adherence to his own philosophical methods. The article concludes by showing some of the advantages of Lonergan’s account of the goodness of being for contemporary debates in ethics. (shrink)

Two recent studies by Joseph Torchia and Paul Griffiths show the importance of Augustine’s critique of the vice of curiositas to contemporary life and thought. Superficially, it might seem that Augustine condemned curiosity because it “seeks to find out whatever it wishes without restriction of any kind.” Though profoundly influenced by Augustine, Bernard Lonergan praised intellectual curiosity precisely insofar as it is motivated by an unrestricted desire to know, rather than by less noble motives. Drawing upon the researches of Torchia (...) and Griffiths, this article endeavors to show that Augustine does not simply equate curiositas with an unrestricted desire to know, and that the virtue of intellectual curiosity as Lonergan understood it is in fact endorsed by Augustine by means of its relationship to the virtue of studiositas. This more nuanced view of the virtues and vices of intellect can provide guidance for contemporary intellectual pursuits, both how to pursue and not to pursue knowledge. (shrink)

In his most recent book Alasdair MacIntyre criticizes the dominant moral system of advanced societies, which “presents itself as morality as such.” Yet, he argues, its primary function is to channel human desires into patterns that will minimize conflict amid distinctively modern economic and political arrangements. Although he appreciates how what he calls “expressionism” has unmasked this ideological function of modern morality, he points out that expressionism is also impotent to provide adequate moral guidance amidst the “conflicts of modernity.” He (...) proposes that Neo-Aristotelianism’s account of reasoning and desire has the ability to overcome the moral failings of these modern modes of thought. Yet he relies on an excessively deductive version of reason and overlooks Aristotle’s fuller account of desire. The article shows how Bernard Lonergan’s account of both provides a superior account of both Aristotle’s own writings and the actual human phenomena of reasoning and desire. (shrink)

Bernard Lonergan’s vocation as a Jesuit was central to his entire life’s work, although this is not well known. This essay shows the indebtedness of Lonergan’s method of self-appropriation owes a great deal to Ignatian spiritual practices. In particular, it shows how Ignatian prayer and Lonergan’s account of the structures of consciousness mutually enhance one another. In particular, it concentrates on how prayer is a transforming encounter between Christ and the one praying.

Lonergan’s written reflections on the notion of form span almost thirty years. Beginning with his 1930s manuscripts on the philosophy of history, Lonergan returned again and again to the problem of clarifying that metaphysical concept. His thought on the issue of form reached its mature stage in 1957 with the publication of Insight. This article first presents an account of the mature, Insight stage of Lonergan’s notion of form. It then shows how Lonergan arrived at that position from his interpretation (...) of Aristotle as set forth in Verbum: Word and Idea in Aquinas. It concludes with some remarks in response to a criticism of Lonergan, commonly leveled by certain Thomist thinkers, according to which Lonergan’s effort to ground philosophy in self-appropriation rather than metaphysics condemns him to a subjectivist or idealist position. Such a critique, I argue, fails to take into account what Lonergan actually held. Indeed, the preference for a metaphysical point de départ is itself vulnerable to a reverse criticism on Lonergan’s part. (shrink)

The "history of mentalities" considers the attitudes of ordinary people to everyday life. The approach is closely identified with the work of the Annales school. However, whereas the Annales historians refer to the material factors which condition human life, historians investigating mentalities examine psychological underpinnings. Historians who first developed guidelines for the history of mentalities were Lucien Febvre and Marc Bloch, who were both concerned with collective systems of belief. Later, Philippe Ariès and Norbert Elias identified and developed theories on (...) early childhood. Finally, Michel Foucault considered the psychology of social deviants and nonconformists. This mode of interpretation provides a means of examining those aspects of life which the linear approach cannot address, such as the pressure of conformity, the sense of accelerating time, and the preoccupation with self.

I argue that Moorean theories of value have a difficult time accommodating the resonance requirement, that is, the platitude that we should value what’s valuable, while a sophisticated reflective endorsement theory of value and the resonance requirement are perfectly consistent. To this extent, a sophisticated reflective endorsement theory has a significant advantage over the Moorean approach. The reflective endorsement theory that I endorse emphasizes systematic exposure to possible sources of satisfaction, as well as a similarity principle of practical rationality.

Albert Einstein's attitude towards quantum mechanics—and statistical physics in general—was a puzzle to many of his contemporaries, and has remained a puzzle to the present. Though he made many significant contributions to statistical physics, he continually refused to regard that branch of science as fundamental. The present essay demonstrates that his attitude towards statistical physics was formed during his earliest investigations—between 1901 and 1903. In particular, it is shown that in Einstein's view, statistical laws are based upon non-statistical assumptions. This (...) view influenced much of his later thinking. A few illustrations are offered, concluding with a discussion of his opposition to quantum mechanics. (shrink)

On this occasion of honouring the achievement of Philip McShane, I would like to recall his earliest and, in my judgment, most important work, Randomness, Statistics and Emergence. In particular, I will recall how that work situated Lonergan’s important breakthrough on statistical method in relation to the major currents of thought on the subject, many of which remain influential still today.
