Reductionist explanations in biology generally assume that biological mechanisms are highly deterministic and basically similar between individuals. A contrasting view has emerged recently that takes into account the degeneracy of biological processes—the ability to arrive at a given endpoint by a variety of available paths, even within the same individual. This perspective casts significant doubt on the prospects for the ability to predict behavior accurately based on brain imaging or genotyping, and on the ability of neuroscience to stipulate ethics.

The life sciences in the 20th century were guided to a large extent by a reductionist program seeking to explain biological phenomena in terms of physics and chemistry. Two scientists who figured prominently in the establishment and dissemination of this program were Jacques Loeb in biology and Ivan P. Pavlov in psychological behaviorism. While neither succeeded in accounting for higher mental functions in physical-chemical terms, both adopted positions that reduced the problem of consciousness to the level of reflexes and associations. (...) The intellectual origins of this view and the impediment to the study of consciousness as an object of inquiry in its own right that it may have imposed on peers, students, and those who followed is explored.

A theologian answers the question: What is the relationship between the hallucinogenic drugs, such as hashish, marihuana, mescaline, psilocybin, LSD, and both mysticism and morality?

Only a negative fundamental option, that is, the engagement of man's core awareness and freedom, can bring about the reality known as mortal sin.

In this paper, we discuss the macroscopic quantum behavior of simple superconducting circuits. Starting from a Lagrangian for electromagnetic field with broken gauge symmetry, we construct a quantum circuit model for a superconducting weak link (SQUID) ring, together with the appropriate canonical commutation relations. We demonstrate that this model can be used to describe macroscopic excitations of the superconducting condensate and the localized charge states found in some ultrasmall-capacitance weak-link devices.

The statistical properties of a single quantum object and an ensemble of independent such objects are considered in detail for two-level systems. Computer simulations of dynamic zero-point quantum fluctuations for a single quantum object are reported and compared with analytic solutions for the ensemble case.

An examination of footnotes, quotations, and name-lists shows that historians try to follow the reality rule - to tell about the past the most likely story that can be sustained by the relevant existing evidence. But this is modified by the maximum impact rule - stories must have evocative force, and the reader should actively confront the past. The maximum impact rule may require the historian to sacrifice some completeness and exactness for evocative impact; and there is no parallel to (...) this sacrifice in scientific explanations. History, as it is practiced, is a rule-bound discipline, with rules and a rhetoric different from those of scientific explanation. There is no need for historians to structure their explanations according to the pattern of the sciences. (shrink)
