Popper's metaphysical research program for the human sciences 1

Popper has provided a model for the scientific explanation of human actions and a metaphysical theory of man which can guide scientific research. In this paper I discuss the problems of the empirical content and nomicity of the Rationality Principle and extend the method of situational analysis to the problem of explaining beliefs. The domain of applicability of the Rationality Principle is bounded on one side by cases in which behavior is determined by processes which can not be influenced by criticism and on the other side by the phenomenon of substantive creativity. However, a large part of human activity lies within its scope.     

Towards a research programme for ethics and technology

In this editorial contribution, two issues relevant to the question, what should be at the top of the research agenda for ethics and technology, are identified and discussed. Firstly: can, and do, engineers make a difference to the degree to which technology leads to morally desirable outcomes? What role does professional autonomy play here, and what are its limits? And secondly, what should be the scope of engineers' responsibility; that is to say, on which issues are they, as engineers, morally obliged to reflect? The research agendas proposed by the authors contributing to this special section, implicitly, give different answers to these questions. We suggest that an explicit discussion of these issues would greatly help in constructing a common research agenda.

Reichenbach's metaphysical picture

Conclusion To recapitulate, then, for Reichenbach probability is the foundation of both metaphysics and epistemology. Metaphysically, probability is fundamental because it is the probability relations among the sequences of events in the world that gives rise to causality, time, and space. Epistemologically, probability is fundamental because empirical knowledge is simply knowledge of probabilities. Even knowledge of observation sentences is considered to be probabilistic knowledge by Reichenbach (EP, pp. 183–188), because Reichenbach's fallibilism leads him to hold that no observation sentence is absolutely incorrigible, and with the advance of scientific knowledge we need to inquire into the probability that our singular observation judgments may be in error.My aim here has not been to argue that Reichenbach succeeded in his magnificent attempt any more than Carnap succeeded in his. But I hope to have convinced you that is was one of the most magnificent attempts by any empiricist philosopher of this or of any other century, and I believe that the effort to understand it and to master its details will as richly repay us as the much greater effort which has been devoted to the study of Carnap's work has already repayed us.     

Van Fraassen's metaphysical move

Various aspects of van Fraassen's constructive empiricism are discussed. His concept of observability is said to have opened few unresolvable dilemmas. It is because of the confusion between observable/non‐observable and testable/metaphysical distinctions. Finally, the constructive empiricist is said to have failed in his attempt at reducing the metaphysical component of science.     

Motor programme information as a separable memory unit

Summary Two experiments produced further evidence for the claim that motor programme information may be considered as a separate memory unit, partially independent of other memory representations. In Experiment 1, it was shown that for the comparison of shared movement components in two actions such as turning the handle and stirring the ingredients, the activation of their motor programmes is required. This is demonstrated by the finding that the execution of the first action, which preactivates its motor programmes, leads to shorter reaction times than under control conditions in which the verbally described action is only spoken. In Experiment 2, it was further shown that the execution of the action does not in every case expedite the assessment of a connection between a prime item and a target item vis à vis verbal repetition, but only where the task requires the activation of motor programmes.

The metaphysical basis of a liberal organ procurement policy

There remains a need to properly analyze the metaphysical assumptions underlying two organ procurement policies: presumed consent and organ sales. Our contention is that if one correctly understands the metaphysics of both the human body and material property, then it will turn out that while organ sales are illiberal, presumed consent is not. What we mean by illiberal includes violating rights of bodily integrity, property, or autonomy, as well as arguing for or against a policy in a manner that runs afoul of Rawlsian public reason.     

Logical space and metaphysical systems

The paper applies the theory presented in “A Formal Ontology of Situations” (this journal, vol. 41 (1982), no. 4) to obtain a typology of metaphysical systems by interpreting them as different ontologies of situations. Four are treated in some detail: Hume's diachronic atomism, Laplacean determinism, Hume's synchronic atomism, and Wittgenstein's logical atomism. Moreover, the relation of that theory to the “situation semantics” of Perry and Barwise is discussed.     

Rawls and the metaphysical tradition

Abstract

Political philosophers, like all philosophers, can be divided into roughly two camps. There are those who are principally metaphysical in their conclusions; feeling that there is something in the nature of things to find or locate to settle the disputes commonly considered to be political disputes, and those others who explicitly reject that type of formulation. Placing the work of John Rawls into one of these categories is, I think, rather challenging; crudely, Rawls can be seen as having made noises of both sorts. The attempt to situate Rawls’s A Theory of Justice both within and beyond the grand metaphysical tradition lies at the center of this paper’s ambitions. This paper also aims to reflect, more generally, on the strengths and weaknesses of Rawls’s Theory. While it will be argued that John Rawls’s early conception of justice is, for the most part, admirable, it will be shown that firstly, Rawls does not fully leave behind the metaphysical inclination that he, as a self-declared non-metaphysical philosopher, is adamant on setting aside, and secondly, although this is very much related to the first point, Rawls’s theory of justice is too heavily grounded in and dependent on the truth of liberalism and thus fails to be adequately mindful of historicism. An examination of the metaphysical flavors in the early articulation of Rawls’s Theory is significant for two main reasons (1) such an examination compels us to ask whether or not Rawls’s Theory was successful, given what we assume were Rawls’s non-metaphysical ambitions, and (2) that the legacy of John Rawls should probably be better off, philosophically speaking (ceterus paribus and by our present lights), if metaphysics were absent in his Theory.

后期墨家形而上学研究

后期墨家指墨子》中的《经上》、《经下》、《经说上》、《经说下》、《大取》和《小取》等六篇所构成的一种学派。在这些文献中,思想家们通过端、体、故等范畴的属性,揭示了本体的特征：基础性、原始性和不可知性。通过披露景、止、亡等特点,后期墨家分析了现象的不确定性。通过分析名与言,后期墨家指出符合说的真理观与认识的图像说。最后,后期墨家还将思维和生存结合起来,以为思维是人类的一个基本存在形式。这一观念具有相当的现代意义。
