Quantum mechanics may be formulated as Sensible Quantum Mechanics (SQM) so that it contains nothing probabilistic except conscious perceptions. Sets of these perceptions can be deterministically realized with measures given by expectation values of positive-operator-valued awareness operators. Ratios of the measures for these sets of perceptions can be interpreted as frequency- type probabilities for many actually existing sets. These probabilities gener- ally cannot be given by the ordinary quantum “probabilities” for a single set of alternatives. Probabilism, or ascribing probabilities to (...) unconscious aspects of the world, may be seen to be an aesthemamorphic myth. (shrink)

Probabilities in quantum theory are traditionally given by Born’s rule as the expectation values of projection operators. Here it is shown that Born’s rule is insufficient in universes so large that they contain identical multiple copies of observers, because one does not have definite projection operators to apply. Possible replacements for Born’s rule include using the expectation value of various operators that are not projection operators, or using vari-.

A simple proof is given that the probabilities of observations in a large universe are not given directly by Born’s rule as the expectation values of projection operators in a global quantum state of the entire universe. An alternative procedure is proposed for constructing an averaged density matrix for a random small region of the universe and then calculating observational probabilities indirectly by Born’s rule as conditional probabilities, conditioned upon the existence of an observation.

The Born rule may be stated mathematically as the rule that probabilities in quantum theory are expectation values of a complete orthogonal set of projection operators. This rule works for single laboratory settings in which the observer can distinguish all the different possible outcomes corresponding to the projection operators. However, theories of inflation suggest that the universe may be so large that any laboratory, no matter how precisely it is defined by its internal state, may exist in a large number (...) of very distantly separated copies throughout the vast universe. In this case, no observer within the universe can distinguish all possible outcomes for all copies of the laboratory. Then normalized probabilities for the local outcomes that can be locally distinguished cannot be given by the expectation values of any projection operators. Thus the Born rule dies and must be replaced by another rule for observational probabilities in cosmology. The freedom of what this new rule is to be is the measure problem in cosmology. A particular volume-averaged form is proposed. (shrink)

It is usually assumed that the quantum state is sufficient for deducing all probabilities for a system. This may be true when there is a single observer, but it is not true in a universe large enough that there are many copies of an observer. Then the probability of an observation cannot be deduced simply from the quantum state (say as the expectation value of the projection operator for the observation, as in traditional quantum theory). One needs additional rules to (...) get the probabilities. What these rules are is not logically deducible from the quantum state, so the quantum state itself is insufficient for deducing observational probabilities. (shrink)

The Jarzynski equality equates the mean of the exponential of the negative of the work (per fixed temperature) done by a changing Hamiltonian on a system, initially in thermal equilibrium at that temperature, to the ratio of the final to the initial equilibrium partition functions of the system at that fixed temperature. It thus relates two thermal equilibrium quantum states.

Here I shall call elements (1)-(3) the quantum state (or the “state”), since they give the quantum state of the universe that obeys the dynamical laws and is written in terms of the kinematic variables, and I shall call elements (4)-(6) the probability rules (or the “rules”), since they specify what it is that has probabilities (here taken to be the results of observations, Oj, or “observations” for short), the rules for extracting these observational probabilities from the quantum state, and (...) the meaning of the probabilities. What I shall write below is largely independent of the meaning of the probabilities, though personally I view them in a rather Everettian way as objective measures for the set of observations with positive probabilities. Usually it is implicitly believed that the observational probabilities depend strongly upon the quantum state. (Sometimes the Everett interpretation [2] is taken to mean that all of physical reality is determined purely by the quantum state, without the need for any additional rules to extract probabilities, but this extreme view seems untenable [4] and will not be adopted here. Instead, I shall discuss the opposite view, that the probabilities are independent of the quantum state.) However, some advocates of inflation[5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22] often claim that our observations do not depend upon the quantum state at all, but rather that inflation acts as an attractor to give the same statistical distribution of observations from any state. In this note, I shall use the framework of state plus rules to discuss this possibility that observational probabilities might be independent of the quantum state. I shall show that this indeed is logically possible, but apparently only if the probability rules are rather ad hoc. If indeed the rules are this ad hoc, so that the probabilities of our observations do not depend upon a quantum state at all, it would seem to leave it mysterious why many of our observations can be simply interpreted as if our universe really were quantum..

Using linear invariant operators in a constructive way we find the most general thermal density operator and Wigner function for time-dependent generalized oscillators. The general Wigner function has five free parameters and describes the thermal Wigner function about a classical trajectory in phase space. The contour of the Wigner function depicts an elliptical orbit with a constant area moving about the classical trajectory, whose eccentricity determines the squeezing of the initial vacuum.

Often it is assumed that a quantum state or a phase-space distribution must be normalizable. Here it is shown that even if it is not normalizable, one may be able to extract normalized observational probabilities from it.

A motivation is given for expressing classical mechanics in terms of diagonal projection matrices and diagonal density matrices. Then quantum mechanics is seen to be a simple generalization in which one replaces the diagonal real matrices with suitable Hermitian matrices.

In lieu of an abstract, here is a brief excerpt of the content: Reviewed by: Hume’s Imagination by Tito MAGRI Don Garrett MAGRI, Tito. Hume’s Imagination. Oxford: Oxford University Press, 2022. xiii + 494 pp. Cloth, $115.00In A Treatise of Human Nature, Hume defines “the imagination” in an inclusive sense as “the faculty, by which we form our fainter ideas”—that is, those that are not memories. In the narrower sense, it is “the same faculty, excluding only our demonstrative and probable (...) reasonings.” Book 1 of the Treatise is largely a work about the imagination in the inclusive sense. Indeed, by Magri’s count, book 1 contains more occurrences of the term imagination/imagine and its variants than of any other philosophical term with the exceptions of impression and idea. Yet until the late 1990s, it was surprisingly rare to find commentators treating the Humean imagination as a focus of attention in its own right, and the complete range of its many roles and operations has largely remained uncatalogued until now. With twelve highly detailed chapters distinguishing no fewer than twenty different “works of the imagination” governed by eighteen different “principles,” Hume’s Imagination is by far the most comprehensive treatment of the faculty to date. Indeed, its only limitations are its two announced ones. First, it does not discuss the imagination in Hume’s subsequent An Enquiry concerning Human Understanding (where its operations receive much less attention) or other writings. Second, it does not discuss the extensive roles played by the imagination in Treatise, book 2 (“Of the Passions”) and book 3 (“Of Morals”)—although readers may hope that a sequel will take up those roles. The wide array of roles and operations that Hume attributes to the inclusive imagination, even in Treatise, book 1 alone, naturally raises the question of how much real unity it has as a psychological natural kind. Magri’s original and provocative answer to this question is that the various operations of Hume’s imagination are unified by their filling in various “cognitive gaps” between the representational contents of the mind’s sensations and memories, on the one hand, and the full range of its cognitive contents and capacities, on the other. Rather than appealing to the kind of purely intellectual ideas posited by Descartes and other so-called rationalists who drew a strong distinction between the intellect and the imagination, however, Hume traces our further abilities to the inferences and mental transitions that the imagination produces utilizing only broadly imagistic ideas. In support of this answer, the book is divided into five parts. Part I, chapter 1 explains the central notion of a “cognitive gap” in terms of a “dualism of representation and inference.” For Magri, “representation” applies only to sensation and memory (although he grants that [End Page 156] “presentation” might be the better term in the case of sensation), as governed by Hume’s self-described first principle: “our simple ideas in their first appearance are deriv’d from simple impressions which are correspondent to them, and which they exactly represent.” This principle is the topic of chapter 2. “Inference” (or, more broadly, “transitions”) applies only to the imagination, which generates new “nonrepresentational” cognitive content in accordance with what Hume calls his second principle: “the liberty of the imagination to transpose and change its ideas.” This principle is the topic of chapter 3. To say, as Magri does, that the only “representational” ideas for Hume are those of memory sounds highly paradoxical, but the intended (nonparadoxical) meaning becomes clear enough on careful reading. Part 2 of the book takes up the role of the imagination in generating specifically conceptual modes of thought. In chapter 4, Magri explains the mind’s capacity for generality in thought through the operation of “abstract ideas” and its capacity to distinguish different aspects of an object through the operation of “distinctions of reason.” In chapter 5, he examines the generation of distinctively modal content through the capacity of the imagination to conceive the same object as having different qualities or being placed in different circumstances. Part 3 turns to the crucial topic of the imagination’s generation of cognition of a world of “realities” beyond sensation and memory through the production of “causal ideas.” Chapter 6... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Did God Deprive Pharaoh of Free Will?Don LeviWhen Pharaoh was reeling from certain later plagues he agreed to free the Israelites. But each time after the plague stopped, God stiffened Pharaoh's heart, and he refused to let them go. Since it was God who did it, Pharaoh had to refuse to release the Israelites; he could not have let them go. So, he was deprived of free will by (...) God.In this article I question this reasoning. I question whether we can conclude from the fact that God did it that Pharaoh could not release them; and from the fact that Pharaoh could not release them, that he did not have free will. I also question whether it is possible to understand what the free will is that God is supposed to have given to all of us and taken from Pharaoh.IThe Exodus is the story of how the Israelites escaped from slavery and constituted themselves as a people. "I am the Lord your God who brought you out of the land of Egypt, the house of bondage" (Exodus 20.2).1 This is how God introduces the Ten Commandments: He is the One who led the Israelites out of Egypt; they are the people whom He freed.The stiffening motif underscores how much more powerful God is than Pharaoh. God tells Moses that Pharaoh will let the Israelites go "only because of a greater might" (3.19), and Pharaoh, replies: "Who is the Lord that I should heed Him and let Israel go?" (5.2). That God is by far the more powerful is underscored by having God say that He will "stiffen Pharaoh's heart so that he will not let the people go" (4.21), and by having Him do so, in the cases of several later plagues. After [End Page 58] each plague Pharaoh agrees to release them, only to change his mind when the plague lifted (or, in the case of the final one, when he has released the Israelites), either because he or God stiffened his heart. The disastrous consequences of these reversals reveal him to be concerned with his status as a god-king rather than with the welfare of his people. The motif is part of the developing argument in the Tanakh for a state ruled, not by a Pharaoh or king, but by God and His laws, as transmitted by His prophet, Moses.The problem of whether God deprived Pharaoh of free will by stiffening his heart is a version of the Problem of Evil, albeit with a focus on what God did, not what He did not do. And this focus on God's apparent misbehavior is not an isolated phenomenon. As Kaufman points out, "The Bible ascribes to God actions that, to our way of thinking, lack moral grounds, or even run counter to our moral sense. Indeed, at times they seem to reflect a ruthless, capricious, demonic being."2 To make God more powerful than Pharaoh the text seems to make God too much like Pharaoh.A different understanding of the story arises if we think of the Israelites as its audience, and if we remind ourselves that it is a stage in their developing relationship with God. As Kaufman explains it, the things said about God in the Exodus story as well as elsewhere "express in their own way boundless adoration and reverence of the One" (Religion, p. 75). Later, the Israelites may find different ways of expressing that adoration and reverence. However, what Kaufman is saying is that by making God's behavior towards Pharaoh seem supramoral and demonic, the Torah really is finding a way to express its awe of Him.Nevertheless, in what follows we will try to understand the text as telling us about God, independently of that developing relationship. We will confine our attention to the question of how God's actions deprived Pharaoh of free will. Is that what stiffening someone's heart does; or is it the fact that God did the stiffening? What is interesting is that those who have tried to offer solutions to the problem do not try to answer these questions... (shrink)

ABSTRACT Contrary to George Bishop's claim, collective deliberation and cue‐taking permit even poorly informed individuals to form opinions that can accurately reflect their values and interests in light of available information. Statistical aggregation of poll results can smooth out offsetting errors and uncertainties and reveal collective preferences that are real, stable, consistent, coherent, differentiated, and responsive to information: preferences that policy makers should pay attention to. Media polls tend to be more useful for this purpose than academic surveys that encourage (...) “don't know” responses and use information‐based filters that bias estimates of collective preferences against lower‐income citizens, minorities, and others who tend to be less well informed. Media polls frequently ask about specific policy issues relevant to policy makers. Even biased poll questions of certain kinds can provide useful information about collective policy preferences.

Many defenders of sweat shop practices by major transnational corporations -- some of whom are Catholic -- claim that by refusing to buy such merchandise, we harm the poor. If we don't buy the merchandise, the corporations will close the factories because they will have no market for their goods and the poor will lose their jobs. "Any job is better than no job," they say.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:Hume's Defence of Causal InferenceDon GarrettFred Wilson. Hume's Defence of Causal Inference. Toronto: University of Toronto Press, 1997. Pp. xii + 439. Cloth, $80.00.According to its introduction, this book "deals solely with the problem of induction [and] solely with the issue of whether Hume is a sceptic with regard to causation and scientific reason" (p. 6). Wilson concludes that although Hume rejects "objective" necessary connections, he is not (...) a sceptic—or at least, no more than a fallibilist "academic" sceptic—about induction. In contrast to several relatively recent commentators, he accepts the traditional view that Hume did pose a general sceptical problem about induction. One of Wilson's many formulations of that problem (111) is this: "How can [inductive] inference habits be justified, shown to be reasonable?" According to Wilson, Hume raised this problem and offered a solution to it. In fact, he holds, Hume provided at least the outlines of the correct solution.The book consists of just three chapters, but each chapter is over one hundred pages long. Not surprisingly, then, it is not really devoted solely to the question of whether Hume was or was not a sceptic about induction. In fact, the book takes up a wide variety of other related topics, incorporating considerable amounts of material [End Page 126] from no fewer than thirteen of Wilson's previously-published articles. It helpfully formalizes arguments wherever possible.The first chapter is a series of set-pieces intended to prepare the way for more tightly focused discussion of Hume's treatment of inductive scepticism. Topics include Hume's two definitions of 'cause,' necessary connections, dispositions, mental activity, the epistemology of scientific instruments, and Hume's treatment of "scepticism with regard to the senses." One recurring theme is that Hume is no proto-Kantian about mental activity or the universality of causation; another is the importance to Hume of his "Rules by which to judge of causes and effects."The second chapter is the centerpiece of the book, for it is here that Wilson tries to show how Hume justifies inductive scientific reasoning. The justification, as Wilson reconstructs it, has two steps. The first step is to argue that we ought to make inductive inferences on the grounds that (as a matter of psychological necessity) we must make such inferences. But this is only half the battle, since there are various ways to make inductive inferences and various strategies and influences that might or might not be allowed to affect the outcome. Hume's chosen way of making inductive inferences, Wilson argues, is the scientific method of "eliminative induction," as embodied in the "Rules by which to judge of causes and effects." Hume's strategy for justifying this method, according to Wilson, is to show that it is "reasonable" by showing that it is the method best suited for a particular practical purpose—namely, the purpose of satisfying our passion of "curiosity." This passion aims not only at the pleasure of exercising our faculties, but also at the achievement of truth, or at least (what seems rather different) of a system of beliefs that will prove "satisfactory to the mind." Accordingly, Wilson takes Hume to argue that using the method of eliminative induction embodied in the "Rules" constitutes "the best we can do" by way of discovering the truth of generalizations and that experience shows other methods to be less satisfactory in attaining the truth. Of course, a method's being the best we can do does not in itself entail that it is good enough to warrant adoption; and to treat the past successes or failures of a particular method as indicative of its future success or failure is to rely on induction itself. Presumably, then, Wilson's Hume is meant to regard the inductive arguments showing the "reasonableness" of the "Rules" as themselves among the inductions that any human being ultimately must accept, regardless of specific methods, strategies, or influences.The book's third and final chapter takes up the challenge posed by the section of Hume's Treatise of Human Nature entitled "Of scepticism with regard to reason," in which Hume argues that "all the rules of logic...

In lieu of an abstract, here is a brief excerpt of the content:Don Quijote and the Law of LiteratureCarl Good (bio)The part is one of these beings, the whole minus this part the other. But the whole minus a part is not the whole and as long as this relationship persists, there is no whole, only two unequal parts.—Rousseau, Social Contract, cited by Paul de Man in Allegories of ReadingBut it is not just that, because it is also a performative.... (...) There is first a performative, the act of positing..., which then moves to a system of tropes; a kind of anamorphosis of tropes takes place, in which all the tropological systems are engendered, as a result of this original act of positing.... It is circulation which is out of hand,... the sheer circulation or play of the signifier, and which is, as you know, the root of error, madness, stupidity and all other evil.—Paul de Man, “The Concept of Irony”Amid a confusion of narrative inversions, misleading appearances, and unresolvable disputes, at least two things are consistent in Don Quijote de la Mancha: first, the knight’s singular fidelity to what I will refer to as a law of literature, which persists like a phantasm of continuity throughout the larger narrative; and, second, the many interruptions of this narrative by the stories, or episodes, recounted by the characters who cross don Quijote’s path (including the knight himself), in the form of speeches, testimonies, plays, jokes, poems, and so on. In at least one strict sense, these other stories have nothing to do with that path other than their interruptions of it and by it. Such a claim has its own strategic value and does not entirely contradict the reasonings of a long history of critics of the Quijote who have tended to argue from a variety of different standpoints for some kind of ideological cohesion that would bind the smaller episodes to the larger story that they interpolate. But at a certain ground zero of interpretation—albeit a paradoxical ground that prohibits a scholarly shelter to be built on it—no argument would be sufficient to establish such a coherence among the work’s separate narrative parts, since such an argument would live in the brief, oneiric intensity of the critic’s testimony and that testimony’s potential effects rather than in the composition of the work itself somewhere beyond its apprehension by reading. Nonetheless, out of the dismembered ensemble of the Quijote what does perhaps effect its own strange kind of life is the very play of ironic interruptions and frictions between the dismembered parts, the profusion of which seems to impose itself as the work’s own aggressive insistence on itself as something which makes sense possible by constantly provoking and unsettling sense. That is where we could begin to speak of don Quijote himself, not only as the phantasmatic agent of this unsettling but also as the mad promise of justice that could be said to motivate it.The play of interruptions in don Quijote’s own story begins to outline the shifting contours and living contradictions of this novel as a “text” in the sense in which Derrida [End Page 44] and others have used the term: that which “names or relates in its way... [a] conflict without encounter between law and singularity” [“Before the Law” 187]. Although the story of this “encounter” has been often recounted, it bears another citation here, at least because it seems to be forgotten more often than it is told. Even when it is told, the story is often muted in homage to the name of Derrida by writers who tacitly assume that Derrida’s is the only possible version of this “conflict without encounter.” That version would be better described as merely one particular ethical shaping or forcing—a powerful one—of a story that has been told, and remains untold, in uncountable ways. Nonetheless, such a democratic assessment of Derrida does not quite justify a dismissal of his version as merely one among others, since, for one thing, it would be unable to account for the astonishing hold that different versions of Derridean “deconstruction” continue to have on the imagination of North American...

Social media is the preferred communication platform for today’s youth, yet little is known of how online intergender communication is shaped by social identity norms. Drawing from the Social Identity and Deindividuation Effects approach, we argue that through depersonalization, online interactions are marked by the salience of social identities and identity performance conforming to perceived norms of behavior. We specifically look at discursive terms and their meaning-making as a strategic performance of gender in uncontrolled social media interactions. We examined a (...) corpus of 442 comments from selected public Indian Facebook pages in two phases over a span of 1 year. Thematic discourse analysis revealed established and emerging discursive strategies within the major themes on feminism and antifeminism, men’s rights, intersectional feminism, and sexual behavior. These meaningful terms are used to modulate identity performance in a heavily contested space, reflecting both consolidation as well as mobilization functions, as proposed by SIDE. The findings highlight that intergender communication on social media is both dependent on existing offline norms, while challenging the same to create new discourses of gender. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:"But I Don’t Feel It":Values and Emotions in the Assessment of Competence in Patients With Anorexia NervosaJochen Vollmann (bio)Keywordscompetence assessment, mental capacity, informed consent, psychiatry, anorexia nervosaThe respect of the self-determination of patients obliges physicians to obtain the patient's consent before providing medical treatment. One important condition for a valid informed consent is the patient's competence to make autonomous health care decisions. Therefore, a proper assessment of competence to (...) make health care decisions is crucial particularly in patients with mental disorders (Vollmann 2000; Helmchen and Vollmann 2001). In recent years, several empirical studies on the assessment of competence in patients suffering from different mental disorders have been performed using the MacArthur Competence Assessment Tool-Treatment (MacCAT-T; Grisso and Appelbaum1998). This assessment tool is based on legal standards of competence such as understanding, reasoning, appreciation, and expressing a choice. Since its first publication, the MacCAT-T has been widely accepted as a "gold standard" of competence assessment in the psychiatric literature. In recent years the MacCAT-T has been applied to patients suffering from depression, schizophrenia, dementia, angina pectoris, and normal controls (for overview, see Welie [2001] and Bauer and Vollmann [2002]).Tan and her colleagues (2006) use the MacCAT-T the first time to assess competence to make treatment decisions in patients with anorexia nervosa. Coming from clinical practice, the authors have noticed that the MacCAT-T might not work in this group of patients. Therefore, they use semi-structured interviews in addition to the MacCAT-T to identify aspects of thinking that might be relevant to the issue of competence to refuse treatment. They use grounded theory techniques for a qualitative analysis of the data as well as five brief, self-administered questionnaires to ascertain levels of psychopathology.The results of the study show that anorexia nervosa can have complex and variable effects on concentration, beliefs, and thought processing without affecting the ability to perform well on the MacCAT-T. At the same time, participants also report a change in their value system as well as in their personal identity. The authors argue that the results of their studies suggest that the competence to refuse treatment might be compromised in [End Page 289] people with anorexia nervosa in ways that are not captured by the MacCAT-T. This is an interesting finding in patients with anorexia nervosa, because in all other studies with patients suffering from mental disorders such as dementia, depression, and schizophrenia, the MacCAT-T identified more patients as limited in their competence to make health care decisions in comparison with other methods of competence assessment such as clinical judgment (Vollmann et al. 2003). The authors argue on the basis on their qualitative, semistructured interviews that anorexia nervosa–specific difficulties with a thought process and the change of values are missed by the MacCAT-T.Furthermore, Tan and her associated could not find a relationship between the participants' scores on the psychopathological scales, the MacCAT-T scores, and their difficulties expressed during the qualitative interviews, although the small size of the study precludes statistical analysis. In an earlier study, clinical dementia scales but not neuropsychological testing correlated with formal (MacCAT-T) and clinical assessment of competence. Therefore, psychopathological factors might play a different role in different subgroups of patients suffering from different mental problems. However, the idea of an objective neuropsychological model of competence assessment, again, finds no support in the presented empirical data.The qualitative data from patients with anorexia nervosa underline the problem of the cognitive bias of the MacCAT-T assessment and the illusion of value-free categories. It has been argued that the cognitive focus for the MacCAT-T is in itself a normative convention and that the MacCAT-T is missing the complexity of the process to make health care decisions in real life. Therefore, values and emotions should be considered in addition to cognitive functions in assessing competence to make health care decisions (Breden and Vollmann 2004; see also "Mental capacity" 2004). Although many authors agree that the cognitive approach of capacity assessment is important but not sufficient for the assessment of competence to make health care decisions, it remains an...

The paper presents research into the effects of the use of negations in directives. Three experiments are described that tested the effects of instructions formulated in various ways: direct and negated commands to focus the attention. Indicators of attention focusing that were used include: the correctness of answers to questions about a selection of comic book pages ; the time needed to name the colours of stimulus words and the level of recall of these words after completion of the colour (...) naming task. The results showed that a direct command influenced all indicators of attention focusing. However, a negated command increased the level of recall of details about the comic book pages, as well as the level of key word recall. Both the automatic process that generates the paradoxical effects of negated commands, as well as the controlled process of reasoning, may be responsible for the results of the memory task. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 21.1 (2001) 37-41 [Access article in PDF] What I Know and Don't Know: A Christian Reflects on Buddhist Practice Mary Frohlich Catholic Theological Union To reflect and write on spiritual practice for publication in an academic journal requires a delicate balancing act. It is not appropriate simply to recount one's experience; nor is it appropriate merely to theorize. I am assisted in this balancing act by a (...) set of categories proposed some years ago by Walter Principe and generally accepted as standard now within the academic field of spirituality. Principe observed that spirituality operates on three interrelated yet distinct levels and that it is crucial for the academician to be clear about which level or levels are being presented. The three are: (1) experience; (2) articulation within wisdom traditions; (3) academic interpretation. 1 My understanding of what is desired in the present context is some of all three but with a primary emphasis on the second. What does Buddhist practice look like from my stance within my Christian "wisdom traditions"? Thus, this is the horizon within which I will present both experience and academic insights.First a bit of autobiographical context. I became a Christian as a young adult, after having been raised in a secular humanist household. My first attempts at a form of meditation as a teenager came from reading Taoist books; in college I experimented with drugs (at that time this was often seen as "spiritual practice") and spent a couple of years very seriously practicing transcendental meditation. Only after all this did I seek baptism and church membership. Since then, my certainty that my call is to be a Christian has not wavered. I spent several years in a Carmelite contemplative monastery, and I now belong to another Roman Catholic religious order.Yet I have repeatedly been drawn to periods of engagement with various practices having Hindu and Buddhist roots.This context is important to describe because I am aware that for me (and for many spiritual seekers today) there can never be a "pure" insertion in a single tradition. I reflected on that recently in an airplane at twenty-five thousand feet, looking down and seeing how totally human constructive activity has reshaped the contours of the land, the rivers, and everything that depends on them. I realized then that the same must be said of the inner contours of my soul. Nearing fifty, I bear the marks [End Page 37] of everything that I have ever done or touched or suffered or known. As I approach this task of reflecting on Buddhist practice from the point of view of a Christian, I cannot do it as a pure outsider. My spiritual practice is Christian in its core, but it has been inextricably shaped by so many other influences--including varieties of Buddhist practice.It is also important to acknowledge the limits of my knowledge about Buddhism and Buddhist practices. My academic exposure to Buddhism is about equivalent to an introductory undergraduate course. As for Buddhist practice, I have participated in a total of five weekend retreats, three one-week retreats, and one three-week retreat. These were all from either Vipassana (Insight Meditation) or Zen (Kwan Um or Diamond Sangha) traditions. Occasionally, I have also had even briefer exposure to other Buddhist traditions. I am very aware that there is much I do not know, or that perhaps I just plain misunderstand, about Buddhism.Yet dialogue requires that I honestly state my views, in their present form, with the hope that in the dialogical process what is misinformed or insensitive can eventually be corrected.Spiritual practice (for Buddhists as well as Christians) involves many different kinds of practices. Practices of charity, such as hospitality or almsgiving, perhaps present the fewest obstacles to mutual understanding, because the practices may be generally similar in both traditions. The ritual practices of a religious tradition, on the other hand, can feel extremely alien to those who do not belong to that religious culture. Paul Hanvey has noted that our reaction to...
