GLOBAL JUSTICE AFTER THE FALL Christian Realism and the "Law of Peoples"

In The Law of Peoples John Rawls casts his proposals as an argument against what he calls “political realism.” Here, I contend that a certain version of “Christian political realism” survives Rawls's polemic against political realism sans phrase and that Rawls overstates his case against political realism writ large. Specifically, I argue that Rawls's dismissal of “empirical political realism” is underdetermined by the evidence he marshals in support of the dismissal and that his rejection of “normative political realism” is in tension with his own normative concessions to political reality as expressed in The Law of Peoples. That is, I contend that Rawls, himself, needs some form of political realism to render persuasive the full range of normative claims constituting the argument of that work.     

From Conceptual Analysis to Serious Metaphysics

Abstract

Habermas’s recent work in epistemology has been marked by a decisive rejection of his earlier epistemic conception of truth in which he understood truth as ‘what may be accepted as rational under ideal conditions’. Arguing that no ‘idealization of justificatory conditions’ can do justice to both human fallibility and the unconditional nature of truth, he has attempted to develop a realistic conception of truth that severs any conceptual link between truth and justification while respecting the epistemic relevance of justification for ascertaining the truth. But realizing this second goal has proved elusive for Habermas because he veers too close to a form of metaphysical realism in his epistemology. By contrast, Hilary Putnam’s recent turn to what he calls ‘natural realism’ is more successful in articulating a form of realism that, in taking its leave of an epistemic conception of truth, still manages to keep its distance from metaphysical realism.     

Putnam's Model-theoretic Argument(s). A Detailed Reconstruction

Two of Hilary Putnam's model-theoretic arguments against metaphysical realism are examined in detail. One of them is developed as an extension of a model-theoretic argument against mathematical realism based on considerations concerning the so-called Skolem-Paradox in set theory. This argument against mathematical realism is also treated explicitly. The article concentrates on the fine structure of the arguments because most commentators have concentrated on the major premisses of Putnam's argument and especially on his treatment of metaphysical realism. It is shown that the validity of Putnam's arguments is doubtful and that realists are by no means forced to accept the theses Putnam ascribes to them. It is concluded that Putnam fails to give convincing arguments for rejecting mathematical or metaphysical realism. Furthermore, Putnam's internal realism is discussed critically. This revised version was published online in August 2006 with corrections to the Cover Date.     

Bhaskar on Open and Closed Systems

Bhaskar’s articulation of his ‘transcendental realism’ includes an argument for a form of causal emergence which would mean the rejection of physicalism, by means of rejecting the causal closure of the physical. His argument is based on an analysis of the conditions for closure, where closed systems manifest regular or Humean relations between events. Bhaskar argues that the project of seeking closure entails commitment to a strong (and implausible) reductionism, which in turn entails the impossibility of science itself; and concludes that we should endorse causal emergence. I argue that Bhaskar’s case grossly overreaches itself; and that he fails to establish the emergentist conclusions which he asserts. Consequently his programme poses no significant threat to physicalism.     

Plantinga’s Skepticism

For over 20 years, Alvin Plantinga has been advocating his Evolutionary Argument against Naturalism, or EAAN. We will argue that this argument functions as an atypical form of global skepticism, and Plantinga’s development of it has repercussions for other types of skepticism. First, we will go over the similarities and differences; for example, the standard ways of avoiding other forms of skepticism, namely by adopting some form of naturalized or externalist epistemology, do not work with the EAAN. Plantinga himself is a naturalized epistemologist, and his skepticism comes from within this perspective. Next, we will look at how Plantinga moved from presenting his skepticism diachronically, as a loop, to presenting it synchronically, as an infinite regress. Finally, we can extend this move from Plantinga’s skepticism to other forms of global skepticism, in so far as these will involve the rejection of our cognitive faculties’ reliability, and formulate them synchronically as well. Global skepticism is often accused of instability, since it leads us to skepticism about all of our beliefs, including belief in the skeptical scenario itself. Yet formulating it as an infinite regress rather than a loop allows the skeptical charge to go forward.     

Plantinga's Probability Arguments Against Evolutionary Naturalism

In Chapter 12 of Warrant and Proper Function , Alvin Plantinga constructs two arguments against evolutionary naturalism, which he construes as a conjunction E&N . The hypothesis E says that "human cognitive faculties arose by way of the mechanisms to which contemporary evolutionary thought directs our attention" (p. 220). With respect to proposition N , Plantinga (p. 270) says "it isn't easy to say precisely what naturalism is," but then adds that "crucial to metaphysical naturalism, of course, is the view that there is no such person as the God of traditional theism." Plantinga tries to cast doubt on the conjunction E&N in two ways. His "preliminary argument" aims to show that the conjunction is probably false, given the fact ( R ) that our psychological mechanisms for forming beliefs about the world are generally reliable. His "main argument" aims to show that the conjunction E&N is self-defeating – if you believe E&N , then you should stop believing that conjunction. Plantinga further develops the main argument in his unpublished paper "Naturalism Defeated" (Plantinga 1994). We will try to show that both arguments contain serious errors.     

PRAGMATISM,REALISM, AND RELIGION

Pragmatism is often thought to be incompatible with realism, the view that there are knowable mind‐independent facts, objects, or properties. In this article, I show that there are, in fact, realist versions of pragmatism and argue that a realist pragmatism of the right sort can make important contributions to such fields as religious ethics and philosophy of religion. Using William James's pragmatism as my primary example, I show (1) that James defended realist and pluralist views in metaphysics, epistemology, ethics, and philosophy of religion, and (2) that these views not only cohere with his pragmatism but indeed are basic to it. After arguing that James's pragmatism provides a credible and useful approach to a number of basic philosophical and religious issues, I conclude by reflecting on some ways in which we can apply and potentially improve James's views in the study of religion.     

Ontology Downgraded All The Way

Willard Quine has recently defended his brand of scientific realism and naturalism (1992). He has expanded his defense (1993, 1996), utilizing observation sentences in their holophrastic guise. He also argues that the latter bear "... significantly on the epistemology of ontology" and provide for the commensurability of theories. I argue that they fail in all these tasks. Further, Quine's long-standing commitment to a kind of scientific realism, on the one hand, and his frequent employment of proxy functions and the rejection of transcendental metaphysics, on the other, constitute an untenable position. A consistent Quinean must abandon scientific realism and ontology.     

Naturalized truth and Plantinga’s evolutionary argument against naturalism

There are three major theses in Plantinga’s latest version of his evolutionary argument against naturalism. (1) Given materialism, the conditional probability of the reliability of human cognitive mechanisms produced by evolution is low; (2) the same conditional probability given reductive or non-reductive materialism is still low; (3) the most popular naturalistic theories of content and truth are not admissible for naturalism. I argue that Plantinga’s argument for (1) presupposes an anti-materialistic conception of content, and it therefore begs the question against materialism. To argue for (2), Plantinga claims that the adaptiveness of a belief is indifferent to its truth. I argue that this claim is unsupported unless it again assumes an anti-materialistic conception of content and truth. I further argue that Plantinga’s argument for (3) is not successful either, because an improved version of teleosemantics can meet his criticisms. Moreover, this version of teleosemantics implies that the truth of a belief is (probabilistically) positively related to its adaptiveness, at least for simple beliefs about physical objects in human environments. This directly challenges Plantinga’s claim that adaptiveness is indifferent to truth.     

A Historically Informed Modus Ponens Against Scientific Realism: Articulation,Critique, and Restoration

There are two primary arguments against scientific realism, one pertaining to underdetermination, the other to the history of science. While these arguments are usually treated as altogether distinct, P. Kyle Stanford's ‘problem of unconceived alternatives’ constitutes one kind of synthesis: I propose that Stanford's argument is best understood as a broad modus ponens underdetermination argument, into which he has inserted a unique (and doubly inductive) variant of the historical pessimistic induction. After articulating three criticisms against Stanford's argument and the evidence that he offers, I contend that, as it stands, Stanford's argument poses no threat to contemporary scientific realism. Nonetheless, upon identifying two useful insights present in Stanford's general strategy, I offer an alternative variant of the modus ponens underdetermination argument, one that, although historically informed by science, requires no inductive premises. I contend that this non-inductive but historically informed variant of the modus ponens clarifies and considerably strengthens the case against scientific realism.     

A Plantingian Pickle for a Darwinian Dilemma: Evolutionary Arguments Against Atheism and Normative Realism

Two of the most prominent evolutionary debunking arguments are Sharon Street's Darwinian Dilemma for Normative Realism and Alvin Plantinga's Evolutionary Argument against Atheism. In the former, Street appeals to evolutionary considerations to debunk normative realism. In the latter, Plantinga appeals to similar considerations to debunk atheism. By a careful comparison of these two arguments, I develop a new strategy to help normative realists resist Street's debunking attempt. In her Darwinian Dilemma, Street makes epistemological commitments that ultimately support Plantinga's structurally similar argument. If Street succeeds in debunking normative realism, I argue, then she also succeeds in debunking atheism. But atheism is a suppressed premise of the Darwinian Dilemma as well as a commitment of almost all normative anti‐realists. If Street's argument entails theism, then the Darwinian Dilemma is internally incoherent and should be abandoned by almost everyone. 1     

结构实在论评析

The epistemological version of structural realism, proposed by Cao Tianyu, has great influence in the philosophy of science. Syntheses has published a special volume discussing the topic. Cao criticizes anti-realism, as well as the epistemic and ontic versions of structural realism. From the concepts of structure, ontology, and construction, he analyzes the objectivity of scientific theories as having five aspects: construction, historicity, holism, revision, and revolution. This paper systematically analyzes and comments on Cao's structural realism. The author agrees with his criticism of the under-determination thesis, is neutral to his argument against ontological discontinuity, and questions his universal language argument.

Is Putnam's Causal Theory of Meaning Compatible with Internal Realism?

Putnam originally developed his causal theory of meaning in order to support scientific realism and reject the notion of incommensurability. Later he gave up this position and adopted instead what he called ‘internal realism’, but apparently without changing his mind on topics related to his former philosophy of language. The question must arise whether internal realism, which actually is a species of antirealism, is compatible with the causal theory of meaning. In giving an answer I begin with an analysis of the content and metaphysical background of scientific realism. I show that it presupposes metaphysical realism and that Putnam's philosophical conversion is due to his becoming aware of the latter's incoherence. After giving a brief sketch of internal realism I conclude by arguing that within this new theoretical framework the causal theory of meaning loses its force as a weapon against incommensurability.

Negation,anti-realism,and the denial defence

Here is one argument against realism. (1) Realists are committed to the classical rules for negation. But (2) legitimate rules of inference must conserve evidence. And (3) the classical rules for negation do not conserve evidence. So (4) realism is wrong. Most realists reject 2. But it has recently been argued that if we allow denied sentences as premisses and conclusions in inferences we will be able to reject 3. And this new argument against 3 generates a new response to the anti-realist argument: keep 1 and 2, avoiding 4 by rejecting 3. My aim in this paper is to see how much work in the fight against anti-realism this new response can really do. I argue that there is a powerful objection to the response: 2 is in tension with the claim that denied sentences can be premisses and conclusions in inferences. But I show that, even given this objection, the new response has an important role to play.     

Responsibility and Judgment

I focus on the type of responsibility that an agent has for actions that express his practical identity, making it appropriate to evaluate him on the basis of those actions. This kind of responsibility is often called attributability. In this paper, I argue for a novel view of attributability—the Judgment Responsiveness View (JRV). According to the JRV, an agent is attributability responsible for an action A if and only if A results from either 1) his responding to his judgments about the (normative) reasons that he has in favor of doing A by doing A or 2) his failing to exercise his capacity to respond to his judgments about the (normative) reasons that he has against doing A by not doing A. The JRV diverges from other views of attributability for actions in two significant respects. First, it is not reasonably thought of as a “deep self view.” According to deep self views, attributable actions are actions that express deep features of the agent, such as his fundamental values, cares, or commitments. As I show, thinking in terms of the deep self is too narrow for attributability. Second, unlike other views, the JRV claims—via condition 2)—that we can be attributionally responsible for actions that result from failing to exercise the attributability‐relevant capacity to avoid them. My argument for the JRV thus shows that attributability is a broader and richer conception of responsibility than has been previously thought.     

Finite additivity,another lottery paradox and conditionalisation

In this paper I argue that de Finetti provided compelling reasons for rejecting countable additivity. It is ironical therefore that the main argument advanced by Bayesians against following his recommendation is based on the consistency criterion, coherence, he himself developed. I will show that this argument is mistaken. Nevertheless, there remain some counter-intuitive consequences of rejecting countable additivity, and one in particular has all the appearances of a full-blown paradox. I will end by arguing that in fact it is no paradox, and that what it shows is that conditionalisation, often claimed to be integral to the Bayesian canon, has to be rejected as a general rule in a finitely additive environment.     

How to Be an Alethically Rational Naturalist

Alvin Plantinga has famously argued that naturalism is self-defeating. Plantinga's argument is, at its heart, an argument from analogy. Plantinga presents various epistemic situations and claims of each that (i) a person in such a situation has an undefeated defeater for each of his beliefs, and (ii) a reflective naturalist is in a relevantly similar situation. I present various epistemic situations and claim of each that a person in such a situation does not have an undefeated defeater for each of his beliefs. I further claim that at least some of these situations are more relevantly like the situation faced by the reflective naturalist than any of the situations Plantinga describes. Therefore, Plantinga's argument fails to establish that the reflective naturalist has an undefeated defeater for each of his beliefs and hence fails to establish that naturalism is self-defeating.     

When Do Replies to the Evolutionary Debunking Argument Against Moral Realism Beg the Question?

Some proponents of the evolutionary debunking argument against moral realism believe that replies that assume substantive moral claims beg the question. In this paper, I give a new account of what's wrong with such replies. On this account, many realists beg the question when they rely on substantive moral claims in their replies to the argument, but naturalists do not. While this account generalizes to some other domains, it allows perceptual and inductive realism to remain undebunked.     

Theology,Metaphysics, and Realism about Truth

This essay examines the theological grounds for rejecting metaphysics and the correspondence theory of truth, and argues that while there are good grounds for rejecting a certain kind of metaphysically oriented theology, metaphysics per se is neither objectionable nor avoidable in Christian theology. In the process, it also defends a realist conception of truth against some recent theological criticisms, and argues that a commitment to a modest version of metaphysical realism and realism about truth is not only philosophically tenable, but also theologically preferable to non‐realist views.
