Are Newcomb problems really decisions?

Richard Jeffrey long held that decision theory should be formulated without recourse to explicitly causal notions. Newcomb problems stand out as putative counterexamples to this ‘evidential’ decision theory. Jeffrey initially sought to defuse Newcomb problems via recourse to the doctrine of ratificationism, but later came to see this as problematic. We will see that Jeffrey’s worries about ratificationism were not compelling, but that valid ratificationist arguments implicitly presuppose causal decision theory. In later work, Jeffrey argued that Newcomb problems are not decisions at all because agents who face them possess so much evidence about correlations between their actions and states of the world that they are unable to regard their deliberate choices as causes of outcomes, and so cannot see themselves as making free choices. Jeffrey’s reasoning goes wrong because it fails to recognize that an agent’s beliefs about her immediately available acts are so closely tied to the immediate causes of these actions that she can create evidence that outweighs any antecedent correlations between acts and states. Once we recognize that deliberating agents are free to believe what they want about their own actions, it will be clear that Newcomb problems are indeed counterexamples to evidential decision theory.     

Biblical criticism and cultural Zionism prior to the first world war*

This essay examines the initial stages of the relationship between Jewish nationalism and modern biblical criticism. Its point of departure is Ahad Ha’am, the founder of cultural Zionism, who kept his distance from biblical criticism, and proceeds with Joseph Klausner, Ahad Ha’am’s successor as the editor of Ha-shiloah, who moved in the opposite direction by incorporating biblical criticism into his own writing and teaching. After examining the opposition to Klausner, the essay turns to the work of Ben-Zion Mossinson, who introduced the results of biblical criticism into the teaching of the Bible in the modern schools of the Yishuv. This initiative generated controversy and broad opposition, especially in the European Hebrew press. Shortly before World War I, and in this controversy’s immediate aftermath, Joseph Klausner, then in Palestine, published a small pamphlet in Hebrew making the case for biblical criticism. At about the same time, in Russia, Max Soloveitchik made a similar argument in a book of his own. Neither of these two works had resounding significance, but each testifies to the growing self-confidence of the exponents of cultural Zionist in promoting modern biblical criticism in the Jewish school. *Research for this easy was completed with generous support from a 2003 Harry Starr Fellowship in Jewish Studies at Harvard University.     

Another Paradox In Naive Set-Theory

Reasonning in naive set theory (with unlimited comprehension), we derive a paradox (a formal contradiction) which can be seen as a variant of the Burali-Forti paradox. Presented by Robert Goldblatt     

Evaluating and Comparing Interventions Designed to Enhance Math Fact Accuracy and Fluency: Cover,Copy, and Compare Versus Taped Problems

An adapted alternating treatments design was used to evaluate and compare the effects of two procedures designed to enhance math fact accuracy and fluency in an elementary student with low cognitive functioning. Results showed that although the cover, copy, compare (CCC) and the taped problems (TP) procedures both increased the student's math fact accuracy and fluency, TP was more effective as it took less time to implement. Discussion focuses on the need to develop strategies and procedures that allow students to acquire basic computation skills in a manner that will facilitate, as opposed to hinder, subsequent levels of skill and concept development.     

The Book of Job and Male Melancholia: A Bizarre Story about Hating Mother God and the Maternal Jesus,Featuring Mel Gibson

This article tells, or advocates, a bizarre story about male revenge. By drawing from literature in the psychology of religion that deals with the Book of Job and by assuming the standpoint of “cultural hermeneutics” in biblical studies, the author playfully takes up an issue identified by Donald Capps: the issue of repressed rage in male melancholia. The author takes his cue from a recent doctoral dissertation from Princeton Theological Seminary. Jacobus Hamman (2000) applies a Winnicottian analysis to the Book of Job and argues that the Book of Job can be a useful pastoral resource today in a number of ways, including his proposal for believers to direct their aggression toward God. Implicit in Hamman’s Winnicottian analysis, but never explicitly stated, is the fact that God is Mother. The plot here is how the Book of Job might lead contemporary American men to hate Mother God and the maternal Jesus, thereby aiding them in externalizing their repressed and self-directed rage. Mel Gibson stars, if only briefly, in this childish story that presses the limits of Christian theology.     

Offspring Effects of Prenatal Alcohol Exposure from Birth to 25 Years: The Seattle Prospective Longitudinal Study

Before alcohol was generally known to cause birth defects, NIAAA in 1974 began funding a population-based Seattle study on alcohol use and pregnancy outcome. Women receiving prenatal care by mid-pregnancy were recruited (N = 1,529) and interviewed at home. Approximately 500 offspring exposed to a range of alcohol levels were examined on 11 occasions between day 1 and 25 years. Neuropsychological and neurobehavioral performance measures are correlated with prenatal alcohol dose, without substantial confounding by socio-demographic or rearing conditions, smoking, nutrition, or other drugs. Deficits in attention, arithmetic skill, spatial-visual memory, and IQ, as well as increased alcohol problems and psychiatric disorders are among offspring outcomes correlated at several ages with maternal drinking during and before pregnancy recognition. Findings are not confined to women who believed they had alcohol problems. Not all exposed offspring appear affected.     

Implicit Motives Modulate Attentional Orienting to Facial Expressions of Emotion

We conducted two studies (Ns=52 and 60) to test the notion that the incentive salience of facial expressions of emotion (FEE) is a joint function of perceivers’ implicit needs for power and affiliation and the FEE’s meaning as a dominance or affiliation signal. We used a variant of the dot-probe task (Mogg & Bradley, 1999a) to measure attentional orienting. Joy, anger, surprise, and neutral FEEs were presented for 12, 116, and 231 ms with backward masking. Implicit motives were assessed with a Picture Story Exercise. We found that power-motivated individuals orient their attention towards faces signaling low dominance, but away from faces that signal high dominance, and (b) that affiliation-motivated individuals show vigilance for faces signaling low affiliation (rejection) and, to a lesser extent, orient attention towards faces signaling high affiliation (acceptance).     

Explication Defended

How can formal methods be applied to philosophical problems that involve informal concepts of ordinary language? Carnap answered this question by describing a methodology that he called “explication." Strawson objected that explication changes the subject and does not address the original philosophical problem; this paper shows that Carnap’s response to that objection was inadequate and offers a better response. More recent criticisms of explication by Boniolo and Eagle are shown to rest on misunderstandings of the nature of explication. It is concluded that explication is an appropriate methodology for formal philosophy.
