论弗雷格的“真之收缩”思想

弗雷格运用逻辑分析的方法,提出了自己独特的"真"之思想,形成了关于"真"的完整理论。在他看来,"真"不具有实体属性,不存在与客体在存在方式或存在状况的符合与对应,"真"只用来表达断定句形式中的断定力。当"5是素数"这个句子带有断定力时,真也就被表达出来,它与"5是素数是真的"表达了同样的内容。另外,他将"真"作为初始概念,认为真是不可定义的。如果对"真"进行定义,将走入"定义的循环"。因为要知道什么是"真",就需要论证表象与现实的一致性,而二者的一致又依赖于"真"的定义。这种思路与做法必将导致循环定义,故弗雷格认为"真"是不可定义的。基于以上两点的分析,他再次对符合论提出批评。他认为,如果符合论对"真"的理解是正确的话,那么结论是"事实比真更为基本,应该在事实的基础上定义真",但这显然是错误的,因为我们总是通过真来确定事实,而不是通过事实来确定真。我们似乎可以在弗雷格思想中找到收缩论的雏型,因为他关于"真"的认识与收缩论在很大程度上是一致的。收缩论最重要的观点在于说"P是真的"和说"P"有相同的涵义,谓词"是真的"是多余的。"真"本身是可收缩的,不带有实体性质。于是,我们可把弗雷格作为表达真之收缩观点的第一位哲学家,虽然他并不是坚定的收缩论者。     

DEFLATIONISM AND THE SUCCESS ARGUMENT

Deflationists about truth typically deny that truth is a causal–explanatory property. However, the now familiar 'success argument' attempts to show that truth plays an important causal–explanatory role in explanations of practical success. Deflationists have standardly responded that the truth predicate appears in such explanations merely as a logical device, and that therefore truth has not been shown to play a causal–explanatory role. I argue that if we accept Jackson and Pettit's account of causal explanations, the standard deflationist response is inconsistent, for on this account even logical properties can be causally explanatory. Therefore the deflationist should remain neutral as to whether truth is a causal–explanatory property, and focus instead on the claim that truth, if it is a property, is a merely logical one.     

Review

I argue in this paper that anyone who accepts the ontology of scientific realism can only accept a pragmatic theory of truth, i.e., a theory on which truth is what it is epistemically right to believe. But the combination of realism with such a theory of truth is a form of internal realism; therefore, a scientific realist should be an internal realist. The strategy of the paper is to argue that there is no adequate semantic or correspondence theory of truth compatible with a realist ontology, that a redundancy theory cannot account for the value of truth, and that the only kind of truth theory which can account for the value of truth, and is compatible with a realist ontology, is a pragmatic theory. The kind of truth theory I wish to defend is objective and naturalistic, and the ontology is realistic. My position is, therefore, one of objective, naturalistic realism.     

Reversing the truth effect: learning the interpretation of processing fluency in judgments of truth

Repeated statements receive higher truth ratings than new statements. Given that repetition leads to greater experienced processing fluency, the author proposes that fluency is used in truth judgments according to its ecological validity. Thus, the truth effect occurs because people learn that fluency and truth tend to be positively correlated. Three experiments tested this notion. Experiment 1 replicated the truth effect by directly manipulating processing fluency; Experiment 2 reversed the effect by manipulating the correlation between fluency and truth in a learning phase. Experiment 3 generalized this reversal by showing a transfer of a negative correlation between perceptual fluency (due to color contrast) and truth to truth judgments when fluency is due to prior exposure (i.e., repetition).     

Truth as transcendental in Thomas Aquinas

Aquinas presents his most complete exposition of the transcendentals inDe veritate 1, 1, that deals with the question “What is truth?”. The thesis of this paper is that the question of truth is essential for the understanding of his doctrine of the transcendentals. The first part of the paper (sections 1–4) analyzes Thomas's conception of truth. Two approaches to truth can be found in his work. The first approach, based on Aristotle's claim that “truth is not in things but in the mind”, leads to the idea that the proper place of truth is in the intellect. The second approach is ontological: Thomas also acknowledges that there is truth in every being. The famous definition of truth as “adequation of thing and intellect” enables him to integrate the two approaches. Truth is a relation between two terms, both of which can be called “true” because both are essential for the conformity between thing and intellect. The second part of the paper (sections 5–7) deals with the manner in which Thomas gives truth a place in the doctrine of the transcendentals, and shows that his conception of truth leads to important innovations in this doctrine: the introduction of relational transcendentals and the correlation between spirit and being. If “truth” is transcendental, it must be convertible with “being”. Sect. 6 discusses objections that Thomas advances himself to this convertibility. Sect. 7 deals with a difficulty in his account of truth as a relational transcendental. Ontological truth expresses a relation to an intellect but the relation to the human intellect is accidental for the truth of things. Essential for their truth can only be a practical intellect that causes things. In this way, Thomas argues, the divine intellect relates to all things.     

Reliabilism and antirealist theories of truth

In order to shed light on the question of whether reliabilism entails or excludes certain kinds of truth theories, I examine two arguments that purport to establish that reliabilism cannot be combined with antirealist and epistemic theories of truth. I take antirealism about truth to be the denial of the recognition-transcendence of truth, and epistemic theories to be those that identify truth with some kind of positive epistemic status. According to one argument, reliabilism and antirealism are incompatible because the former takes epistemic justification to be recognition-transcendent in a certain sense that conflicts with the latter’s denial of the recognition-transcendence of truth. I show that, because the recognition-transcendence of reliabilist justification is significantly weaker than the recognition-transcendence required by a realist conception of truth, antirealist theories of truth that deny the strong transcendence of truth do not threaten the externalist character of reliabilism. According to the second argument, reliabilism cannot be combined with an epistemic truth theory because reliabilists analyze positive epistemic status in terms of truth but epistemic theorists analyze truth in terms of positive epistemic status. However, I argue that reliabilists who wish to adopt an epistemic theory of truth can avoid circularity by appealing to a multiplicity of positive epistemic statuses.     

Coherence and the Truth Connection

There is an objection to coherence theories of knowledge to the effect that coherence is not connected with truth, so that when coherence leads to truth this is just a matter of luck. Coherence theories embrace falliblism, to be sure, but that does not sustain the objection. Coherence is connected with truth by principles of justified acceptance that explain the connection between coherence and truth. Coherence is connected with truth by explanatory principle, not just luck.     

Reasoning and rationalization

Contra Lewis, it is argued that the correspondence theory is a genuine rival theory of truth: it goes beyond the redundancy theory; it competes with other theories of truth; it is aptly summarized by the slogan 'truth is correspondence to fact'; and it really is a theory of truth.     

Fluency and positivity as possible causes of the truth effect

Statements’ rated truth increases when people encounter them repeatedly. Processing fluency is a central variable to explain this truth effect. However, people experience processing fluency positively, and these positive experiences might cause the truth effect. Three studies investigated positivity and fluency influences on the truth effect. Study 1 found correlations between elicited positive feelings and rated truth. Study 2 replicated the repetition-based truth effect, but positivity did not influence the effect. Study 3 conveyed positive and negative correlations between positivity and truth in a learning phase. We again replicated the truth effect, but positivity only influenced judgments for easy statements in the learning phase. Thus, across three studies, we found positivity effects on rated truth, but not on the repetition-based truth effect: We conclude that positivity does not explain the standard truth effect, but the role of positive experiences for truth judgments deserves further investigation.     

真之多元论的混合合取难题

真之多元论认为不同的领域有不同的真性质。混合合取的合取支由不同领域的命题所构成,从而具有不同的真性质。多元论需要解释混合合取具有何种真性质。尽管多元论有若干解决办法,如假设逻辑领域特有的真性质、假设合取命题特有的真性质、假设某种普遍的真性质,但都存在一定的问题。混合合取仍旧对多元论构成挑战。另外,强一元论面临辖域问题,即,适真性的范围较窄。相比较而言,弱一元论优于多元论和强一元论。     

The Concept of Truth in a Finite Universe

The prospects and limitations of defining truth in a finite model in the same language whose truth one is considering are thoroughly examined. It is shown that in contradistinction to Tarskirs undefinability theorem for arithmetic, it is in a definite sense possible in this case to define truth in the very language whose truth is in question.     

On Moderate Pluralism About Truth and Logic

According to moderate truth pluralism, truth is both One and Many. There is a single truth property that applies across all truth-apt domains of discourse, but instances of this property are grounded in different ways. Propositions concerning medium-sized dry goods might be true in virtue of corresponding with reality while propositions pertaining to the law might be true in virtue of cohering with the body of law. Moderate truth pluralists must answer two questions concerning logic: (Q1) Which logic governs inferences concerning each truth-apt domain considered separately? (Q2) Which logic governs inferences that involve several truth-apt domains? This paper has three objectives. The first objective is to present and explain the moderate pluralist’s answers to (Q1) and (Q2). The second objective is to argue that there is a tension between these answers. The answer to (Q1) involves a commitment to a form of logical pluralism. However, reflection on the moderate truth pluralist’s answer to (Q2) shows that they are committed to taking logic to be topic neutrality. This, in turn, forces a commitment to logical monism. It would seem that the moderate truth pluralist cannot have it both ways. The third objective is constructive in nature. I offer an account of what moderate truth pluralists should say about logic and how they might resolve the tension in their view. I suggest that, just like moderate truth pluralists distinguish truth proper and “quasi-truth,” they should endorse a distinction between logic proper and “quasi-logic.” Quasi-truth is truth-like in the sense that instances of quasi-truth ground instances of truth. Quasi-logic is logic-like in the sense that it concerns arguments that are necessarily truth-preserving but are not generally so in a topic neutral way. I suggest that moderate truth pluralists should be monists about truth proper and logic proper but pluralists about quasi-truth and quasi-logic. This allows them to say that logic proper is topic neutral while still accommodating the idea that, for different domains, different arguments may be necessarily truth-preserving.     

James Fodor's Christian Theory of Truth: Is it Christian?

The 'task confronting contemporary theology', says James Fodor, 'is that of the rehabilitation or recovery of a distinctively Christian vision of truth' ( Christian Hermeneutics [Oxford, 1995] p. 72). In this paper I examine Fodor's attempt to construct a Christian or transformational theory of truth. I argue that his analysis of truth in terms of transformation leads to a concept of truth which is both subjective and relative. I argue further that Fodor's truth theory is either committed to a version of creative anti-realism, according to which the existence of basic structure of the world is determined by our linguistic activities, or it implies that although our language doesn't correspond to the world, we should go on making our theological truth claims anyway. I conclude that Fodor's Christian theory of truth is in most crucial respects not Christian at all.     

The seventh servant: The implications of a truth drive in Bions theory of 'O'

Drawing upon Bion's published works on the subjects of truth, dreaming, alpha‐function and transformations in ‘O’, the author independently postulates that there exists a ‘truth instinctual drive’ that subserves a truth principle, the latter of which is associated with the reality principle. Further, he suggests, following Bion's postulation, that ‘alpha‐function’ and dreaming/phantasying constitute unconscious thinking processes and that they mediate the activity of this ‘truth drive’ (quest, pulsion), which the author hypothesizes constitutes another aspect of a larger entity that also includes the epistemophilic component drive. It purportedly seeks and transmits as well as includes what Bion (1965, pp. 147‐9) calls ‘O’, the ‘Absolute Truth, Ultimate Reality, O’ (also associated with infi nity, noumena or things‐in‐themselves, and ‘godhead’) (1970, p. 26). It is further hypothesized that the truth drive functions in collaboration with an ‘unconscious consciousness’ that is associated with the faculty of ‘attention’, which is also known as ‘intuition’. It is responsive to internal psychical reality and constitutes Bion's ‘seventh servant’. O, the ultimate landscape of psychoanalysis, has many dimensions, but the one that seems to interest Bion is that of the emotional experience of the analysand's and the analyst's ‘evolving O’ respectively (1970, p. 52) during the analytic session. The author thus hypothesizes that a sense of truth presents itself to the subject as a quest for truth which has the quality and force of an instinctual drive and constitutes the counterpart to the epistemophilic drive. This ‘truth quest’ or ‘drive’ is hypothesized to be the source of the generation of the emotional truth of one's ongoing experiences, both conscious and unconscious. It is proposed that emotions are beacons of truth in regard to the acceptance of reality. The concepts of an emotional truth drive and a truth principle would help us understand why analysands are able to accept analysts’ interpretations that favor the operation of the reality principle over the pleasure principle—because of what is postulated as their overriding adaptive need for truth. Ultimately, it would seem that Bion's legacy of truth aims at integrating fi nite man with infi nite man.     

TRUTH TELLING AS REPARATIONS

Abstract: International instruments now defend a “right to the truth” for victims of political repression and violence and include truth telling about human rights violations as a kind of reparation as well as a form of redress. While truth telling about violations is obviously a condition of redress or repair for violations, it may not be clear how truth telling itself is a kind of reparations. By showing that concerted truth telling can satisfy four features of suitable reparations vehicles, I defend the idea that politically implemented modes of truth telling to, for, and by those who are victims of gross violation and injustice may with good reason be counted as a kind of reparations. Understanding the doubly symbolic character of reparations, however, makes clearer why truth telling is unlikely to be sufficient reparation for serious wrongs and is likely to be sensitive to the larger context of reparative activity and its social, political, and historical background.     

A Minimalist Theory of Truth

This article, after briefly discussing Alfred Tarski's influential theory of truth, turns to a more recent theory of truth, a deflationary, or minimalist, theory. One of the chief elements of a deflationary, or minimalist, theory of truth is that it replaces the question of what truth is with the question of what “true” does. After setting out the central features of the minimalist theory of truth, the article explains the motivation for opting for such a position. In addition, it provides some reasons for thinking that such a theory of truth is “minimal” or “deflationary” in the way that contemporary truth theorists have claimed it to be.     

Two French Variations on Truth: Ricoeur's Attestation and Foucault's “Parrhesiastic” Attitude

Both Ricoeur and Foucault, apparently independently of each other, dedicated much effort to provide an account of truth that goes far beyond the truth of sentences, propositions, or judgments. While well aware of the speech act theory and pragmatics, they want to go beyond a formalism of rules of speech or arguments and integrate the attitude of the one who speaks in the very notion of truth. They see truth not merely as a property of statements, but as an existential process in such a way that the truth of statements is linked to the historically situated speaker. Truth as a property of statements is related to truth as an event. However, both reject any form of historicism or relativism.

I examine Ricoeur's notion of attestation and Foucault's notion of parrhesia, showing how both notions represent a kind of “poetics of truth”, which combines the existential position of the speaker and the historical circumstances of utterance. I show the extent to which both poetics of truth are political and ethical and how successful each poetics is: Ricoeur believes that he can maintain a claim to universality whereas Foucault abandons such a claim and instead subscribes to a radical singularity of the event of speech in a mode of truth that is, as he says, “polemic”.
