The prefrontal cortex has long been suspected to play an important role in cognitive control, in the ability to orchestrate thought and action in accordance with internal goals. Its neural basis, however, has remained a mystery. Here, we propose that cognitive control stems from the active maintenance of patterns of activity in the prefrontal cortex that represent goals and the means to achieve them. They provide bias signals to other brain structures whose net effect is to guide the flow of (...) activity along neural pathways that establish the proper mappings between inputs, internal states, and outputs needed to perform a given task. We review neurophysiological, neurobiological, neuroimaging, and computational studies that support this theory and discuss its implications as well as further issues to be addressed. (shrink)

Preeminent psychoanalyst Mortimer Ostow believes that early childhood emotional attachments form the cognitive underpinnings of spiritual experience and religious motivation. His hypothesis, which is verifiable, relies on psychological and neurobiological evidence but is respectful of the human need for spiritual value. Ostow begins by classifying the three parts of the spiritual experience: awe, Spirituality proper, and mysticism. After he pinpoints the psychological origins of these feelings in infancy, he discusses the foundations of religious sentiment and practice and the brain (...) processes associated with spiritual experience. He then focuses on spirituality's relationship to mood regulation, and the role of negative spirituality in fostering religious fundamentalism and demonic possession. Ostow concludes with an analysis of an essay by the psychoanalyst Donald M. Marcus, who recounts his own spiritual experience during a Native American-style "vision quest" in the woods. Marcus's account demonstrates the constructive potential of spirituality and the way in which spirituality retrieves and recapitulates feelings of attachment to the mother. Persuasively and brilliantly argued, _Spirit, Mind, and Brain_ brings the disciplines of religion, behavorial neuroscience, and philosophy to bear on a groundbreaking new method for understanding religious ritual and belief.

The paper explores the promise of ethical codes as a means to control unethical behavior in business. After a review of arguments for ethical codes from outside the business system, the paper outlines the arguments for codes from inside the business system at the level of the industry, firm and individual executive.The paper then discusses the problems of code design — the dilemma between specific practices and general precepts — and offers a model for a thoroughgoing code. This is followed (...) by a discussion of the problems of promulgation and code enforcement. (shrink)

Evidentialism holds that the justified attitudes are determined entirely by the person's evidence. This book is a collection of essays, mostly jointly authored, that support and apply evidentialism.
