自由优先于德性——罗尔斯伦理思想的一种解读

罗尔斯伦理思想总体上可归结为一种权利伦理学;“自由优先于德性”是罗尔斯伦理思想的基本原则之一,这个原则以“自我优先于目的”为形式根据,以“正义(权利)优先于德性”为质料内容。罗尔斯权利伦理揭示了现代自由社会的道德特征和道德要求,提出了诸多新的伦理理念和伦理观点,但也存在着一些局限性。     

Psychology of Science/Theology of Science: Reaching Out or Narrowing?

Formalizing a “psychology of science” today will constrain intellectual freedom in ways more likely stultifying than liberating. We should be more improvisational in seeking ideas from academic psychology to develop a more comprehensive purview. I suggest that a psychology of science should look at systematic theology and empirical theology. Liberal theologians have long experience trying to distill from religion those structural aspects that affirm openness in a search for truth. Science, as well as religion, has its myths and rituals, but theologians are more experienced than scientists at a large mythohistorical scale. There are distortions in the extreme degree to which psychological science has traditionally emphasized empiricism, positivism, hypothesis testing, and falsifiability. I argue for less critical reduction and more creative augmentation. This could include looking outside academia at cognitive competencies of people in trades. Exaggerated parsimony is an old story. This is illustrated by the opposition to David Hartley's 1749 theory of neural oscillations. There is an inexorable “margin of uncertainty” where scientific prediction and control can never outstrip the new uses to which human beings put ideas. Facts and values interact in this margin; theology has long made a home there, but scientists sometimes have been excessive in rejecting the “naturalistic fallacy.” There is also often a degree of disingenuousness in psychology's reluctance to take subjective phenomena seriously; here there may be lessons in how empirical theology has handled subjectivity, as well as in taking an honest look at the way much of the methodology of experimental psychology incorporates subjective assessments. Feist's book is a start, but these things need more thought before codifying a psychology of science.     

Interplay of Biomechanical Constraints and Kinematic Strategies in Selecting Arm Postures

In this study, the authors examined the interplay between biomechanics and control strategies in the resolution of excess degrees of freedom at the joint level. Seven participants made aimed arm movements from 30 starting points and several starting postures to targets. Final arm postures for movements to a target exhibited substantial joint angle variation. Through regression modeling and by comparing observed final arm postures with biomechanically plausible postures, the authors identified 3 kinematic strategies: (a) Maintain deviations from the average angle at the starting point to the joint's final posture; (b) make torso rotations that are a fixed proportion of shoulder rotations; and (c) adopt a characteristic combination of 4 wrist-positioning approaches. The results demonstrated that kinematic strategies can account for substantial variance in final arm postures, if one takes into account 2 types of individual differences—those that arise inevitably from biomechanical constraints and those that reflect choices in movement strategy.     

“道德”探幽

道德既是人之为人的内在规定性,亦是人的自由存在方式,既是人对存在的反思性把握,亦是人的反思性存在方式。     

Autonomy,Sanity and Moral Theory

The concept of autonomy plays atleast two roles in moral theory. First, itprovides a source of constraints upon action:because I am autonomous you may not interferewith me, even for my own good. Second, itprovides a foundation for moral theory: humanautonomy has been thought by some to producemoral principles of a more general kind.This paper seeks to understand what autonomyis, and whether the autonomy of which we arecapable is able to serve these roles. We wouldnaturally hope for a concept of autonomy thatis value-neutral rather than value-laden. Thatis to say, we would want the judgement that Iam autonomous to depend wholly on, say,structural features of my psychology, and in noway to require us to make ethical judgements, orother value judgements. Being value-neutral isperhaps desirable in a concept of autonomyserving the first role, and plausiblyindispensible in one playing the second. Ishall argue, however, that value-neutral conceptionsof autonomy are impoverished and out of linewith our intuitions; set out and defendan explicitly value-laden conception ofautonomy; and explore the implications of such a view for theability of autonomy to play the rolesmentioned above.     

Freedom and Rationality as Predictors of Cross-National Happiness Patterns: The Role of Income as a Mediating Variable

Freedom and rationality have traditionally been viewed as essential ingredients to the 'pursuit of happiness'. Previous research has found that the way in which happiness is linked to freedom and other attributes of individualistic society is affected by the income level. This paper formulates a structural model of the linkage between political freedom, rationality, and happiness which takes explicit account of income as a mediating variable. Since income is hypothesized to be linked to the degree of freedom and rationality prevailing in a society, this approach permits to distinguish between direct and indirect linkages of happiness to freedom and rationality. Estimating the model with cross-national data yields the following key findings: (1) Happiness is positively related to freedom as well as to rationality at high freedom/rationality levels and negatively at low levels. (2) Whereas freedom affects happiness only indirectly (through its impact on income), rationality has both direct and indirect effects on happiness.     

Reformation Resources for Contemporary Eco‐Justice Theology

Reformation theology has two significant contributions to make to a renewal of environmental theology. Its heritage of sin exposes the fact that human efforts at intervention in the environment are only ambiguously good and in need of redemption themselves. Its heritage of freedom exposes some efforts toward environmental healing as works‐righteousness, available to be transformed by God in hope for a heavenly and earthly future.
