Belief-Ful Realism and Scientific Realism

Despite tensions between Tillich's category of belief-ful realism and a view of science that embraces metaphysical and epistemological realism, a constructive relationship can be developed between the two. Both are based on common understandings about reality. Belief-ful or theonomous realism thus affirms scientific realism. On the other hand, scientific realism is open to the ecstatic, self-transcending elements of belief-ful realism. Finally, Tillich's formulation of the relationship between culture and religion can be reformulated specifically to include scientific and technological culture.     

Scientific Realism Within Perspectivism and Perspectivism Within Scientific Realism

Perspectivism is often understood as a conception according to which subjective conditions inevitably affect our knowledge and, therefore, we are never confronted with reality and facts but only with interpretations. Hence, subjectivism and anti-realism are usually associated with perspectivism. The thesis of this paper is that, especially in the case of the sciences, perspectivism can be better understood as an appreciation of the cognitive attitude that consists in considering reality only from a certain ‘point of view’, in a way that can avoid subjectivism. Whereas the way of conceiving a notion is strictly subjective, the way of using it is open to intersubjective agreement, based on the practice of operations whose nature is neither mental nor linguistic. Therefore, intersubjectivity (that is a ‘weak’ sense of objectivity) is possible within perspectivism. Perspectivism can also help understand the notion of ‘scientific objects’ in a referential sense: they are those ‘things’ that become ‘objects’ of a certain science by being investigated from the ‘point of view’ of that science. They are ‘clipped out’ of things (and constitute the ‘domain of objects’ or the ‘regional ontology’ of that particular science) by means of standardized operations which turn out to be the same as those granting intersubjectivity. Therefore this ‘strong’ sense of objectivity, which is clearly realist, coincides with the ‘weak’ one. The notion of truth appears fully legitimate in the case of the sciences, being clearly defined for the regional ontology of each one of them and, since this truth can be extended in an analogical sense to the theories elaborated in each science, it follows that are real also the unobservable entities postulated by those theories.     

关于科学实在论的几点思考

本文从一个特选的角度来透视科学实在论和反实在论之间的争论。我认为,在争论物理学对象是否实在之前和之时,我们须问:物理学的实在性为何需要证明。这种需要分成两个层次,一是物理学内部的对象和假说是否实在,这要由物理学的发展去解决。二是物理学对象相对于日常对象是否实在。日常实在对象提供了实在概念的原型,但并不提供实在概念的定义,不能因为物理学对象不似日常而否定其实在性。然而,由于物理学对象只能由数学通达,所以,“实在”概念在物理学中已经发生了变化。     

The Indispensability Argument for Mathematical Realism and Scientific Realism

Confirmational holism is central to a traditional formulation of the indispensability argument for mathematical realism (IA). I argue that recent strategies for defending scientific realism are incompatible with confirmational holism. Thus a traditional formulation of IA is incompatible with recent strategies for defending scientific realism. As a consequence a traditional formulation of IA will only have limited appeal.     

From Standard Scientific Realism and Structural Realism to Best Current Theory Realism

I defend a realist commitment to the truth of our most empirically successful current scientific theories—on the ground that it provides the best explanation of their success and the success of their falsified predecessors. I argue that this Best Current Theory Realism (BCTR) is superior to preservative realism (PR) and the structural realism (SR). I show that PR and SR rest on the implausible assumption that the success of outdated theories requires the realist to hold that these theories possessed truthful components. PR is undone by the fact that past theories succeeded even though their ontological claims about unobservables are false. SR backpeddles to argue that the realist is only committed to the truth about the structure of relations implied by the outdated theory, in order to explain its success. I argue that the structural component of theories is too bare-bones thin to explain the predictive/explanatory success of outdated theories. I conclude that BCTR can meet these objections to PR and SR, and also overcome the pessimistic meta-induction.     

两种科学观:本质主义与非本质主义

科学是现代文明的主要智力源泉,现代科技则是现代文明发展的主动力,是现代文明最炫目的一部分。如果说现代文明已陷入深重危机(如全球性生态危机、核战争的潜在危险和现代生物技术以及人工智能技术的应用风险),那么这深重危机与现代科技的理念、方法和发展方向直接相关。反思现     

Semantic Challenges to Scientific Realism

This paper is concerned with connections between scientific and metaphysical realism. It is not difficult to show that scientific realism, as expounded by Psillos (1999) clearly qualifies as a kind of metaphysical realism in the sense of Putnam (1980). The statement of scientific realism therefore must not only deal with underdetermination and the dynamics of scientific theories but also answer the semantic challenges to metaphysical realism. As will be argued, the common core of these challenges is the proposition that a (metaphysical) realist semantics leads to semantic agnosticism in the sense that we are unable to grasp the proper meanings and referents of our linguistic expressions. Having established this, I will focus more specifically on the question of whether scientific realism—in its state-of-the-art account—has the resources to make reference to scientific concepts intelligible such that the semantic challenges can be answered.     

The Problem of Obligation,the Finite Rational Will,and Kantian Value Realism

Abstract

Robert Stern's Understanding Moral Obligation is a remarkable achievement, representing an original reading of Kant's contribution to modern moral philosophy and the legacy he bequeathed to his later-eighteenth- and early-nineteenth-century successors in the German tradition. On Stern's interpretation, it was not the threat to autonomy posed by value realism, but the threat to autonomy posed by the obligatory nature of morality that led Kant to develop his critical moral theory grounded in the concept of the self-legislating moral agent. Accordingly, Stern contends that Kant was a moral realist of sorts, holding certain substantive views that are best characterized as realist commitments about value. In this paper, I raise two central objections to Stern's reading of Kant. The first objection concerns what Stern identifies as Kant's solution to the problem of moral obligation. Whereas Stern sees the distinction between the infinite will and the finite will as resolving the problem of moral obligation, I argue that this distinction merely explains why moral obligations necessarily take the form of imperatives for us imperfect human beings, but does not solve the deeper problem concerning the obligatory nature of morality—why we should take moral norms to be supremely authoritative laws that override all other norms based on our non-moral interests. The second objection addresses Stern's claim that Kantian autonomy is compatible with value realism. Although this is an idea with which many contemporary readers will be sympathetic, I suggest that the textual evidence actually weighs in favor of constructivism.     

Scientific Realism: Old and New Problems

Scientific realism is a doctrine that was both in and out of fashion several times during the twentieth century. I begin by noting three presuppositions of a succinct characterization of scientific realism offered initially by the foremost critic in the latter part of the century, Bas van Fraassen. The first presupposition is that there is a fundamental distinction to be made between what is “empirical” and what is “theoretical”. The second presupposition is that a genuine scientific realism is committed to their being “a literally true story of what the world is like”. The third presupposition is that there are methods for justifying a belief in the empirical adequacy of a theory which do not also suffice to justify beliefs in its literal truth. Each of these presuppositions raises a number of problems, some of which are quite old and others rather newer. In each case, I briefly review some of the old problems and then elaborate the newer problems.     

论元伦理学中的康德式建构主义

康德主义伦理学被怀疑论者看作一种心灵-独立的实在论,并因此遭到它的批评。实在论者则把康德主义伦理学作为一种心灵-独立的实在论加以辩护。科斯嘉承继并推进了罗尔斯所实现的康德主义的元伦理学转向,在回应对康德主义外在实在论批评和辩护的同时,提出了一种建构主义的程序实在论,并把它作为一种内在的实在论加以辩护,完成了道德实在论的内在转变。但是这种康德式建构主义却面临着这样一个困难,即它作为一种内在的实在论同时是一种非认知主义。从理论的融贯性来看,与这种康德式内在实在论相适合的应是一种康德式内在认知主义。     

Toward a Purely Axiological Scientific Realism

The axiological tenet of scientific realism, “science seeks true theories,” is generally taken to rest on a corollary epistemological tenet, “we can justifiably believe that our successful theories achieve (or approximate) that aim.” While important debates have centered on, and have led to the refinement of, the epistemological tenet, the axiological tenet has suffered from neglect. I offer what I consider to be needed refinements to the axiological postulate. After showing an intimate relation between the refined postulate and ten theoretical desiderata, I argue that the axiological postulate does not depend on its epistemological counterpart; epistemic humility can accompany us in the quest for truth. Upon contrasting my axiological postulate against the two dominant non-realist alternatives and the standard realist postulate, I contend that its explanatory and justificatory virtues render it, among the axiologies considered, the richest account of the scientific enterprise.     

Some Problems with Scientific Relativism and Moral Realism

In its early development philosophy of science did not allow the possibility of a relativistic approach with regard to explanation of external phenomena. Relativism was seen as justified exclusively with regard to internal phenomena, for example, in the realm of moral and aesthetic judgment. In the realm of moral judgment, external realism functions as a necessary hypothesis, according to which our moral judgment and moral decisions have a real effect in the external world, for which we can be held responsible. A paradigm shift in the theory of science, inaugurated by Th. S. Kuhn, led to the rise of relativism with regard to judgment in the realm of external phenomena and specifically with regard to the validity of scientific theories. Critics of relativism do not take into account that it is not enough to point out the logical inconsistency of relativism. Most arguments for scientific justification of external realism are doomed to failure, because they do not take into account the role of the judgmental subject. In this article I will show that the role of “second nature” is significant not only for the constitution of moral realism, but also for the implementation of scientific naturalism.
