试论语言科学的经验性基础

语言学一般被定义为是一门经验科学 ,但是这门科学的认识论基础并不是毫无问题的。在语言学理论和语言的经验材料之间没有一种简单而直接的关系。对语言材料的界定、选择和抽象是任何语言学理论工作者所必须做的。这个过程就涉及到了必要的选择 ,不同的选择即会导致不同的理论构建。而这些有关的选择是与一定的理论预设有关。因此 ,从经验到理论是一个辨证互动的复杂过程。理论观念实际上从一开始就是所采用的经验材料的一部分。     

On the Prospects for Virtue Contextualism:Comments on Greco

John Greco has proposed a new sort of contextualism which exhibits a principled grounding in an agent reliabilist virtue epistemology. In this paper I will discuss Grecos two main reasons in favor of virtue contextualism. The first reason is that his account of knowledge can be derived from a more general theory of virtue and credit. The second reason consists in the thesis that a virtue contextualist solution to the lottery problem is superior to standards contextualism. With regard to the first claim, I raise some questions concerning the status and the content of the crucial conditions for Grecos theory of intellectual credit. With regard to the second claim, I try to show that his arguments do not succeed in establishing the superiority of virtue contextualism to standards contextualism. I close with some remarks on the relation among Grecos virtue contextualism, the traditional approach to the theory of knowledge and the proper domain of contextualism.     

Pragmatic Contextualism

Contextualism in epistemology has traditionally been understood as the view that “know” functions semantically like an indexical term, encoding different contents in contexts with different epistemic standards. But the indexical hypothesis about “know” faces a range of objections. This article explores an alternative version of contextualism on which “know” is a semantically stable term, and the truth‐conditional variability in knowledge claims is a matter of pragmatic enrichment. The central idea is that in contexts with stringent epistemic standards, knowledge claims are narrowed: “know” is used in such contexts to make assertions about particularly demanding types of knowledge. The resulting picture captures all of the intuitive data that motivate contextualism while sidestepping the controversial linguistic thesis at its heart. After developing the view, the article shows in detail how it avoids one influential linguistic objection to traditional contextualism concerning indirect speech reports, and then answers an objection concerning the unavailability of certain types of clarification speeches.     

Epistemic Contextualism

Any contextualist approach to knowledge has to provide a plausible definition of the concept of context and spell out the mechanisms of context changes. Since it is the dynamics of context change that carry the main weight of the contextualist position, not every mechanism will be capable of filling that role. In particular, I argue that one class of mechanisms that is most popularly held to account for context changes, namely those that arise out of shifts of conversational parameters in discourses involving knowledge claims, are not suited to the job because they cannot account for the genuinely epistemic nature of the context shift. A form of epistemic contextualism that defines the context through the structure of our epistemic projects is suggested. Context changes in this account are linked to changes in the background assumptions operative in our epistemic projects and the methods used to carry out our inquiries.     

Leave Truth Alone: On Deflationism and Contextualism

Abstract: According to deflationism, grasp of the concept of truth consists in nothing more than a disposition to accept a priori (non‐paradoxical) instances of the schema: (DS) It is true that p if and only if p. According to contextualism, the same expression with the same meaning might, on different occasions of use, express different propositions bearing different truth‐conditions (where this does not result from indexicality and the like). On this view, what is expressed in an utterance depends in a non‐negligible way on the circumstances. Charles Travis claims that contextualism shows that ‘deflationism is a mistake’, that truth is a more substantive notion than deflationism allows. In this paper, I examine Travis's arguments in support of this ‘inflationary’ claim and argue that they are unsuccessful.     

Contextualism and the Knowledge Norms

Epistemic contextualism is widely believed to be incompatible with the recently popular view that knowledge is the norm of assertion, practical reasoning, or belief. I argue in this article that the problems arising for contextualism from the mentioned normative views are only apparent and can be resolved by acknowledging the fairly widespread phenomenon of non‐obvious context‐sensitivity (recently embraced by even some of contextualism's most ardent former critics). Building on recent insights about non‐obvious context‐sensitivity, the article outlines an independently attractive contextualist account of the mentioned epistemic norms and provides a solution to the puzzles they give rise to in a contextualist framework.     

Contextualism and the Factivity Problem

Epistemological contextualism - the claim that the truth-value of knowledge-attributions can vary with the context of the attributor - has recently faced a whole series of objections. The most serious one, however, has not been discussed much so far: the factivity objection. In this paper, I explain what the objection is and present three different versions of the objection. I then show that there is a good way out for the contextualist. However, in order to solve the problem the contextualist has to accept a relationalist version of contextualism.     

Contextualism and Relativism

Philosophical Studies -     

The Argument from Skepticism for Contextualism

Epistemic contextualism was originally motivated and supported by the response it provides to skeptical paradox. Although there has been much discussion of the contextualist response to skeptical paradox, not much attention has been paid to the argument from skepticism for contextualism. Contextualists argue that contextualism accounts for the plausibility and apparent inconsistency of a set of paradoxical claims better than any classical invariantist theory. In this paper I focus on and carefully examine the argument from skepticism for contextualism. I argue not only that the prima facie advantage of contextualism is specious, but also that contextualism is in fact at a competitive disadvantage with respect to two classical invariantist views. I also argue that contextualism takes an arbitrary and unsatisfying strategy in its response to skepticism. That contextualism is alone in taking this arbitrary strategy marks a second competitive disadvantage for it. In addition, I argue that the contextualist response to skeptical paradox regenerates a skeptical paradox which contextualism is powerless to solve. Consequently, the argument from skepticism for contextualism fails. Furthermore, this feature of the contextualist response to skeptical paradox completely undermines the motivation and support for contextualism deriving from its treatment of skeptical paradox. I conclude that the argument from skepticism for contextualism fails, and that the contextualist response to skeptical paradox fails to motivate contextualism, pending the success of another argument for the contextualist thesis.     

Normative Reasons Contextualism

This article argues for the view that statements about normative reasons are context‐sensitive. Specifically, they are sensitive to a contextual parameter specifying a relevant person's or group's body of information. The argument for normative reasons contextualism starts from the context‐sensitivity of the normative “ought” and the further premise that reasons must be aligned with oughts. It is incoherent, I maintain, to suppose that someone normatively ought to φ but has most reason not to φ. So given that oughts depend on context, a parallel view about normative reasons is needed. It is shown that the resulting view solves notorious puzzles involving apparently conflicting but equally plausible claims about reasons. These puzzles arise especially in cases where agents have limited information or false beliefs. In these cases, we feel torn between reasons claims that take into account the limitations of the agent's perspective and apparently conflicting claims that are made from a more objective point of view. The contextualist account developed here accommodates both objectivist and subjectivist intuitions. It shows that all of the claims in question can be true, provided that they are relativized to different values of the relevant information parameter. Also, contextualism yields a fruitful approach to the debate about having reasons and the alleged failure of the so‐called “factoring account”.     

Epistemic Contextualism and the Semantics-Pragmatics Distinction

Contextualism, in its standard form, is the view that the truth conditions of sentences of the form ‘S knows that P’ vary according to the context in which they are uttered. One possible objection to contextualism appeals to what Keith DeRose calls a warranted assertability maneuver (or WAM), according to which it is not our knowledge sentences themselves that have context-sensitive truth conditions, but what is pragmatically conveyed by the use of such sentences. Thus, proponents of WAMs argue, the context sensitivity of knowledge attributions is not a semantic phenomenon but a pragmatic one. I examine a number of WAMs and show that each (i) is seriously flawed, or (ii) undercuts standard contextualism if we hold a minimalist conception of semantic content. I propose an alternative form of contextualism that accommodates minimalism and is immune to the second type of WAM, and show that this new form of contextualism shares the virtues of standard contextualism.     

Contextualism and the issue of continuity

In the study of continuity development, two models have predominated in the research literature: organismic vs. contextual model. The first, the organismic, is characterized by the claim that early individual characteristics—what I refer to as traits—have predictive power in relation to subsequent behavior. The contextual model, on the other hand, stresses that predictive power of early individual characteristics is rather weak and that the best predictor of later behavior is the nature of the environment the individual occupies at that point in time. In this paper, both models are presented (including an interactive one), using data from a longitudinal study of attachment. Findings from children 1 to 18 years reveal that 18-year-old models of attachment, as well as the level of psychopathology shown, are best predicted by concurrent family status (whether the mother and father are divorced), rather than early attachment or the interaction between early attachment and family status.
