The neuropsychology of religious activity in normal and selected clinical populations is reviewed. Religious activity includes beliefs, experiences, and practice. Neuropsychological and functional imaging findings, many of which have derived from studies of experienced meditators, point to a ventral cortical axis for religious behavior, involving primarily the ventromedial temporal and frontal regions. Neuropharmacological studies generally point to dopaminergic activation as the leading neurochemical feature associated with religious activity. The ventral dopaminergic pathways involved in religious behavior most closely align with the (...) action-extrapersonal system in the model of 3-D perceptual–motor interactions proposed by Previc . These pathways are biased toward distant space and also mediate related extrapersonally dominated brain functions such as dreaming and hallucinations. Hyperreligiosity is a major feature of mania, obsessive-compulsive disorder, schizophrenia, temporal-lobe epilepsy and related disorders, in which the ventromedial dopaminergic systems are highly activated and exaggerated attentional or goal-directed behavior toward extrapersonal space occurs. The evolution of religion is linked to an expansion of dopaminergic systems in humans, brought about by changes in diet and other physiological influences. (shrink)

With respect to many, if not most issues, there exist significant differences of opinion among individuals who seem to be equally knowledgeable and sincere. Individuals who apparently have access to the same information and are equally interested in the truth affirm incompatible perspectives on, for instance, significant social, political, and economic issues. Such diversity of opinion, though, is nowhere more evident than in the area of religious thought. On almost every religious issue, honest, knowledgeable people hold significantly diverse, often incompatible (...) beliefs. -/- Religious diversity of this sort can fruitfully be explored in many ways — for instance, from psychological, anthropological, or historical perspectives. The current discussion, however, will concern itself primarily with those key issues surrounding religious diversity with which philosophers, especially analytic philosophers of religion, are most concerned at present. Specifically, our discussion will focus primarily on the following questions: How pervasive is religious diversity? Does the reality of this diversity require a response? Can a person who acknowledges religious diversity remain justified in claiming just one perspective to be correct? If so, is it morally justifiable to attempt to convert others to a different perspective? Can it justifiably be claimed that only one religion offers a path into the eternal presence of God? The answers to such questions are not simply academic. They increasingly have great impact on how we treat others, both personally and corporately. (shrink)

The theme of this paper can be introduced in this way: does a pluralist approach to religion entail a pluralist approach to religion? My theme is not that odd, because I have two notions of pluralism in mind. There is what I will call ‘tolerant pluralism’ and what I will call ‘religious pluralism’. And thus my question is ‘Does tolerant pluralism re religion entail religious pluralism?’.

In the literature on toleration, epistemic arguments are commonly equated with John Stuart Mill's fallibilism according to which toleration of opinions is a necessary means to the attainment of truth. This conflation does not capture the variety of those arguments and it results from the fact that a proper analysis of epistemic arguments for religious toleration and a systematic account of their different types are still lacking. The purpose of this article is to provide such an analysis and to argue (...) that those arguments come in four different types, which I name fallibilism, religious belief-forming process, epistemic parity, and differentiated access to religious truth or divine message. I also offer a mapping of those different types of arguments using the standard epistemic notions of justification, truth, and belief coupled with a distinction of focus in the epistemological approach – whether individually or socially focused.

We’ve all heard the familiar saying, “ignorance is bliss.” It may also be true that “ignorance is intolerant.” But it seems to be at least sometimes true that intolerance is produced by something else: overconfidence in the truthfulness of one’s own opinions. Awareness of and avoidance of such overconfidence may be a path towards tolerating those with whom one disagrees. And this could be true in religion as well as in other areas of belief. In his 2005 article “On Religious (...) Diversity and Tolerance,” Philip L. Quinn argues that awareness of religious diversity, coupled with various other considerations, leads to a degree of modesty about the truth claims of one’s religion, and that such modesty leads to tolerance of other religions. However, in his 2007 paper “Is Uncertainty a Sound Foundation for Religious Tolerance,” William Lane Craig takes issue with Quinn’s position, arguing that Quinn’s “radical skepticism” about religious beliefs is not warranted and that “doubt” is not a sound foundation for tolerance. In this paper I contend that cognitive humility is warranted, that it is not a form of skepticism, that it does not entail doubt, and that it may contribute significantly to religious tolerance. I defend Quinn’s thesis by offering a version that is based on certain epistemic considerations that help the reader to see Quinn’s argument in a new and strengthened light. I then argue that Quinn’s approach to tolerance has at least one significant advantage over the approach proposed by Craig: acceptability to all religious traditions. (shrink)
