Absence Causation and a Liberal Theory of Causal Explanation

For the framework of event causation—i.e. the framework according to which causation is a relation between events—absences or omissions pose a problem. Absences, it is generally agreed, are not events; so, under the framework of event causation, they cannot be causally related. But, as a matter of fact, absences are often taken to be causes or effects. The problem of absence causation is thus how to make sense of causation that apparently involves absences as causes or effects. In an influential paper, Helen Beebee offers a partial solution to the problem by giving an account of causation by absence (i.e. causation in which absences are supposed to be causes). I argue that Beebee's account can be extended to cover causation of absence (i.e. causation in which absences are supposed to be effects) as well. More importantly, I argue that the extended Beebeeian account calls for a major modification to David Lewis's theory of causal explanation, usually taken as standard. Compared to the standard theory, the result of this modification, which I shall call ‘the liberal theory of causal explanation’, has, among other things, the advantage of being able to accommodate causal explanations in which the explananda are not given in terms of events.     

TOUCHING THE MIND OF GOD: PATRISTIC CHRISTIAN THOUGHT ON THE NATURE OF MATTER

This paper seeks to examine the nature of matter from an Orthodox Christian patristic perspective, specifically that of St. Gregory of Nyssa, and compare this with David Bohm's concept of wholeness and the implicate order. By examining the ramifications of the doctrine of creation ex nihilo, the basic nature of matter as being rooted in the mind of God reveals itself, and furthermore shows that certain conceptions of quantum physics can provide language with which to give voice to this ancient view.     

Exemplarist Environmental Ethics

This article argues that environmental ethics can deemphasize environmental problem‐solving in preference for a more exemplarist mode. This mode will renarrate what we admire in those we have long admired, in order to make them resonate with contemporary ethical needs. First, I outline a method problem that arose for me in ethnographic fieldwork, a problem that I call, far too reductively, “solution thinking.” Second, I relate that method problem to movements against “quandary ethics” in ethical theory more broadly. Third, I discuss some interpretive work I am engaged in about Henry David Thoreau and how it bears on the methodological issues my fieldwork raised. I argue that some of the most important icons of right relation to environment, especially Francis of Assisi and Thoreau, should be envisioned as far more politically invested than they usually are. They demonstrate to scholars of religious ethics that an exemplarist ethic focused on character need not neglect politics.     

Reason and Emotion in the Ethics of Self‐Restraint

In this essay I argue that Reinhold Niebuhr's ethics of self‐restraint, though promising, is based on an incomplete and imprecise moral psychology. Although Niebuhr claims that reason cannot provide a sufficient grounding to motivate self‐restraint, he does not disclose which human capacity might serve this purpose. I suggest that we can address this oversight by strengthening Niebuhr's tentative embrace of David Hume, and by developing a concept of the emotions in order to explain how human beings can cultivate a stable inclination to self‐restraint. This project is informed by and in the service of feminist critiques of Niebuhr and social concerns.     

THE PRESENT STATE OF THE COMPARATIVE STUDY OF RELIGIOUS ETHICS: An Update

A survey of developments over the last forty years suggests that little progress has been made in the development of comparative religious ethics as a discipline. While authors working in this field have produced a number of interesting works, the field lacks structure, including an agreement on the basic purpose, terms, and approaches by which contributions may be evaluated as better or worse. I provide an account of this history, suggesting that a way forward will involve marrying ethicists' interest in arguments with close attention to the more and less formal structures by which groups of people organize the giving and taking of reasons.     

Henry David Thoreau's Anti‐Work Spirituality and a New Theological Ethic of Work

Although Henry David Thoreau stands outside the Christian canon, his outlook on the relations among spirituality, ecology, and economy highlights how Christian theologians can develop a theological work ethic in our era of economic and ecological precarity. He can furthermore help theologians counter the pro‐work bias in much Christian thought. In Walden, Thoreau shows that the best work is an ascetic practice that reveals and reaps the abundance of nature and connects the person to the immanent divine and thereby glimpsing eternity. Thoreau thus offers the outline of a transformed theology of work even as he challenges Protestant vocationalism in the early industrial era. He is therefore a fitting if challenging guide for formulating a theology of the self as agent and product of work, at a moment when the postindustrial ideal of work that is both meaningful and remunerative seems ever more unattainable while the negative impact of our work on nonhuman nature is ever more apparent.     

Simulating a skilled typist: a study of skilled cognitive-motor performance

We review the major phenomena of skilled typing and propose a model for the control of the hands and fingers during typing. The model is based upon an Activation-Trigger-Schema system in which a hierarchical structure of schemata directs the selection of the letters to be typed and, then, controls the hand and finger movements by a cooperative, relaxation algorithm. The interactions of the patterns of activation and inhibition among the schemata determine the temporal ordering for launching the keystrokes. To account for the phenomena of doubling errors, the model has only “type” schemata—no “token” schemata—with only a weak binding between the special schema that signals a doubling, and its argument. The model exists as a working computer simulation and produces an output display of the hands and fingers moving over the keyboard. It reproduces some of the major phenomena of typing, including the interkeystroke interval times, the pattern of transposition errors found in skilled typists, and doubling errors. Although the model is clearly inadequate or wrong in some of its features and assumptions, it serves as a useful first approximation for the understanding of skilled typing.     

Perceptual interference and hemispheric specialization

Two experiments evaluated the effect of stimuli presented at fixation on the recognition of faces or random shapes presented to the left or right visual half-field (VF). Increasing the processing demands of the center stimulus produced a large, linear decrease in recognition from both VFs for both faces and shapes. Recognition of random shapes was decreased more in the right visual field by center digits and in the left VF by center faces and shapes. In addition, interference was found between the VF faces and the center digits to the left of fixation. It was concluded that differences in the processing capacity of the two hemispheres are a function of the verbal-nonverbal nature of the stimuli at a later stage in processing but that the two hemispheres may also differ along other perceptual dimensions at an earlier stage of visual recognition.
