A growing number of social scientists fear that marriage may be on the rocks and few doubt that matrimony, as we have known it, has undergone a wrenching period of change in the past several decades. Andrew Cherlin, a leading sociologist of the family, speaks of "the de-institutionalization of marriage," conceding a point to conservative commentators who have argued that marriage and the family...

This article analyzes the fallacy of wrenching from context, using the dialectical notionsof commitment and implicature as tools. The data, a set of key examples, is used tosharpen the conceptual borderlines around the related fallacies of straw man, accent,misquotation, and neglect of qualifications. According to the analysis, the maincharacteristics of wrenching from context a...

The central purpose of this inquiry is to analyze the fallacy of wrenching from context. Logic textbooks and other accounts briefly explain this manipulative technique as a linguistic distortion of the other party’s thesis. It is a fallacy in which there are two or more parties engaged in argumentation and one has interpreted or represented the position of another in an improper way that has fa...

Increasing the amount of physical activity has been observed to ameliorate the progression of Alzheimer's disease (AD), as well as enhance neurogenesis. Choi et al. in this issue of Neuron report that the expression of Presenilin 1 (PS1) variants, responsible for the early onset of familial AD, are capable of mitigating the regenerative effects associated with increased activity and environment...

The successful execution of any contact task fundamentally requires the application of wrenches (forces and moments) consistent with the task. We develop an algorithm for computing the entire set of wrenches consistent with achieving a given augmented contact mode (e.g., sliding at contact 1, rolling at contact 2, and approaching potential contact 3) for one fixed and one moving part in the plane.
