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.     

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.     

The (Old) New Realism: What Holt Has to Offer for Ecological Psychology

As Ecological Psychology pushes into new areas, success will be made easier by a rediscovery its theoretical history, in particular the “New Realism”, lead in part by E. B. Holt. Three New Realists tenants seem particularly relevant: (1) we experience reality, (2) relations are real, and (3) things are what you see when you see those things. Though the two groups differ in terms of their conception of perception, and what can be perceived, their conceptions are related in very insightful ways. Further, the comparison reemphasizes the extent of unique empirical claims ecological psychologists make, and grounds those claims within a larger framework for psychology as a whole. This makes obvious the need for further work on the mathematics of invariants, the physiological mechanisms of information extraction, and the behaviors of perception.

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.     

Scientific Realism and Quantum Mechanics: Revisiting a Controversial Relation

The article examines the controversial relation of scientific realism with quantum mechanics. To this end, two distinct discussions are invoked: the discussion about ‘realism’ in the context of quantum mechanics and the discussion about ‘scientific realism’ in the context of the general philosophy of science. The aim is to distinguish them in order, first, to argue that the former—revolving around ‘local realism’ and the theorems of Bell and Kochen–Specker—unjustifiably identifies realism with features of a particular worldview, and thereby fosters the impression that the failure of ‘local realism’ in quantum experiments constitutes a failure of scientific realism too; and, second, in light of the latter discussion, to claim that scientific realism and quantum mechanics can be compatible—there is ground for dealing with quantum measurement simply as a physical mind-independent interaction. Therefore, a realist approach to the theory is possible despite its notorious measurement problem, even if the issue of its interpretation is still disputed.     

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.     

Three Paradigms of Scientific Realism: A Truthmaking Account

This paper investigates the nature of scientific realism. I begin by considering the anomalous fact that Bas van Fraassen's account of scientific realism is strikingly similar to Arthur Fine's account of scientific non-realism. To resolve this puzzle, I demonstrate how the two theorists understand the nature of truth and its connection to ontology, and how that informs their conception of the realism debate. I then argue that the debate is much better captured by the theory of truthmaking, and not by any particular theory of truth. To be a scientific realist is to adopt a realism-relevant account of what makes true the scientific theories one accepts. The truthmaking approach restores realism's metaphysical core—distancing itself from linguistic conceptions of the debate—and thereby offers a better characterization of what is at stake in the question of scientific realism.     

Scientific Realism and the Meanings of Theoretical Terms

In contemporary philosophy of science, there are many interesting arguments for and against scientific realism with regard to the meaningfulness and truthfulness of theoretical statements. Some anti-realists hold that since many important concepts in scientific theories have no specific referents, the relevant theoretical statements are therefore either false or meaningless. In this essay, I join the debates concerning the plausibility of scientific realism by focusing on two intertwined issues： first, that of how we can we explicate the meaningfulness of theoretical statements, especially statements pertaining to unobservable objects, and second, that of the meaningfulness of theoretical statements for our acceptance of scientific realism.
