In his Knowledge and Belief (1962), Hintikka establishes his system of epistemic logic with the KK (Knowing that One Knows, in symbols, Kp→KKp) principle (KK for short). However, his system of epistemic logic and the KK principle are grounded upon his strong notion of knowledge, which requires that knowledge is infallible, that is, it makes further inquiry pointless, and becomes ‘discussion-stopper’; knowledge implies truth, to wit, cognitive agents will not be mistaken in their knowledge; cognitive agents will be ‘perfect logicians’, (...) i.e. they have infinitive capability of logical inference. Hintikka calls the argument for KK from the strong notion of knowledge as the ‘transcendental argument’ for KK. Obviously, the strong notion of knowledge is far away from our ordinary conception of knowledge; based on such a strong sense of knowledge, epistemic logic has met the problem of logical omnipotence, and is difficult to apply in our ordinary cognitive practice. Moreover, there is no close connection of the KK principle with internalism or externalism. (shrink)

Jin Yuelin 金嶽霖 was a Chinese philosopher and logician. From 1914 to 1920 he studied at the University of Pennsylvania and Columbia University, and received his Ph.D. in political science from Columbia in 1920. From 1921 until 1925, he studied in Europe and visited Great Britain, Germany, France, and Italy, among other countries. During these years, he studied at the London School of Economics and Political Sciences and at the University of Cambridge. At the end of 1925, Jin returned to (...) China and soon became a professor at Tsinghua University, where he began teaching logic in 1926. In 1931–1932, Jin went to Harvard University as a visiting scholar to study logic with the logician Henri M. Sheffer... (shrink)

Jin Yuelin (1895?1984), a Chinese logician and philosopher, is greatly influenced by Hume's and Russell's philosophies. How should we respond to Hume's problem of induction? This is an important clue to understand Jin's whole philosophical career. The first section of this paper gives a brief historical review of Russell and Jin. The second section outlines Hume's skeptical arguments against causality and induction. The third section expounds Russell's justification of induction by discussing his views on Hume's skepticism, causality, principle of induction, (...) and empirical postulates. The fourth section clarifies Jin's justification of induction by discussing his critique of Hume's epistemology and his arguments for the reliability of causality and the eternal truth and apriority of the principle of induction. The final section compares Jin's justification of induction with Russell's and concludes that there are similarities and differences between their projects and that both their attempts fail. This paper takes the similar responses to the problem of induction by Jin and Russell to demonstrate the communication that there has been between Chinese philosophers and the Western ones. (shrink)

This article systematically challenges Kripke's modal argument and Soames's defence of this argument by arguing that, just like descriptions, names can take narrow or wide scopes over modalities, and that there is a big difference between the wide scope reading and the narrow scope reading of a modal sentence with a name. Its final conclusions are that all of Kripke's and Soames's arguments are untenable due to some fallacies or mistakes; names are not “rigid designators”; if there were rigid designators, (...) description(s) could be rigidified to refer fixedly to objects; so names cannot be distinguished in this way from the corresponding descriptions. A descriptivist account of names is still correct; and there is no justification for Kripke's theory of rigid designation and its consequences. (shrink)

After a brief review of the notions of necessity and a priority, this paper scrutinizes Kripke's arguments for supposedly contingent a priori propositions and necessary a posteriori propositions involving proper names, and reaches a negative conclusion, i.e. there are no such propositions, or at least the propositions Kripke gives as examples are not such propositions. All of us, including Kripke himself, still have to face the old question raised by Hume, i.e. how can we justify the necessity and universality of (...) general statements on the basis of sensory or empirical evidence?

There are two problematic assumptions in Kripke’s semantic argument against descriptivism. Assumption 1 is that the referential relation of a name to an object is only an objective or metaphysical relation between language and the world; it has nothing to do with the understanding of the name by our linguistic community. Assumption 2 is that descriptivism has to hold that, if name a has its meaning and the meaning is given by one description or a cluster of descriptions, the description (...) should supply a set of necessary and sufficient conditions for determining what a designates; and that it is possible for us to find out such a setof conditions. Emphasizing the sociality, intentionality, conventionality and historicity of language and meaning, this paper rejects Assumption 1, and argues that Assumption 2 is an unfair interpretation of descriptivism, and it is not necessary for descriptivists to hold Assumption 2. This paper finally concludes that Kripke’s semantic argument against descriptivism fails. (shrink)

Jin Yuelin’s logical and philosophical thought was deeply influenced by the philosophy of Bertrand Russell. The same influence existed also in the case of his view on truth, which was considerably close to the views maintained by Russell in his phase of logical atomism. In their investigations, Russell and Jin not only focused on similar topics, but also occupied similar philosophical positions, such as realism in the domain of ontology, empiricism in epistemology, and the correspondence theory in the domain of (...) the theory of truth. Nevertheless, Jin Yuelin’s view on truth was not only a mere imitation or recapitulation or even plagiarized copy of Russell’s, but also contained innovations and characteristics of its own. Jin, for example, emphasized certain general characteristics of truth, including the notion of truth as a relational quality, that truth is not a matter of degree, and that it is relative neither to time and space nor to the different types of knowledge. By so doing, Jin underlined the objectiveness, reliability, and transcendence of true propositions. By arguing that the correspondence theory of truth possessed strong foundations in common sense, Jin set out to defend the role of common sense in philosophy and science, maintaining that the former cannot be completely eliminated and arguing against the notion that any modification of a part of common sense would ultimately be founded on yet another segment of common sense. Moreover, Jin delivered his own response against the theory of the gap between “subject and object/the internal and the external,” which had been used to question the correspondence theory of truth, proposing a variety of cognitivist theory, which defined facts as “the given” (datum) that has been received and arranged. Most importantly, facts are cognitive constructs created on the basis of “the given” and encapsulate both subjectiveness and objectiveness. Jin Yuelin was a modern Chinese philosopher who had achieved profound erudition in both Chinese and Western thought, and, above all, an independent an profoundly original thinker. (shrink)

There are two problematic assumptions in Kripke’s semantic argument against descriptiv­ism. Assumption 1 is that the referential relation between a name and its bearer is only a metaphysical relation between language and the world; it has nothing to do with our public linguistic practice. Assumption 2 is that if name N has its meaning and the meaning is given by one description or a cluster of descriptions, the description(s) should supply the necessary and sufficient condition for determining what N designates; (...) it is possible for us to find out such a condition for fixing the referent of N. Emphasizing the sociality, conventionality and historicity of language and meaning, this paper criticizes Assumption 1 and Assumption 2, and concludes that Kripke’s semantic argument fails. (shrink)

This paper argues for a hybrid and alternative theory of names—Socio-historical Causal Descriptivism, which consists of six claims: (1) the referring relation between a name and an object originates from a generalized “initial baptism” of that object. (2) The causal chain of the name N firstly and mainly transmits informative descriptions of N’s bearer. (3) The meaning of N consists of an open-ended collection of informative descriptions of N’s bearer acknowledged by a linguistic community. (4) With respect to practical needs (...) of agents there is s weighted order in the collection of descriptions of N’s bearer. (5) The meaning or even partial meaning of N, together with the background of a discourse, the network of knowledge, speaker’s intention, etc., determines the referent of N. (6) All names have their own referents, including physical individuals, and parasitic, fictional, or intensional objects; there are few names absolutely without reference. (shrink)

To systematically answer two questions “how does language work?” and “where does linguistic meaning come from?” this paper argues for SocialConstructivism of Language and Meaning which consists of six theses: the primary function of language is communication rather than representation, so language is essentially a social phenomenon. Linguistic meaning originates in the causal interaction of humans with the world, and in the social interaction of people with people. Linguistic meaning consists in the correlation of language to the world established by (...) collective intentions of a language community. Linguistic meaning is based on the conventions produced by a language community in their long process of communication. Semantic knowledge is empirical and encyclopedic knowledge distilled and condensed, and the uses of language accepted by a linguistic community. Language and meaning change rapidly or slowly as the communicative practice of a linguistic community does. The crucial point of SCLM is to focus on the triadic relation among language, humans and the world, rather than the dyadic relation between language and the world. (shrink)

This paper divides the sophisms and paradoxes put forth by Chinese thinkers of the pre-Qin period of China into six groups: paradoxes of motion and infinity, paradoxes of class membership, semantic paradoxes, epistemic paradoxes, paradoxes of relativization, other logical contradictions. It focuses on the comparison between the Chinese items and the counterparts of ancient Greek and even of contemporary Western philosophy, and concludes that there turn out to be many similar elements of philosophy and logic at the beginnings of Chinese (...) and Greek civilizations.

ABSTRACTBy means of critical reflection on the current situation of Chinese philosophy, this article aims to clarify two different approaches to philosophy. One is for scholars to focus on original texts and thought tradition, concerned with interpretation and inheritance; even in this way, scholars can achieve theoretical innovation through creative interpretation. The other is for researchers to face up questions from academics and from reality, and mainly to do theoretical creation in philosophy on a profound theoretical background, strictly following academic (...) norms and standards. For contemporary Chinese philosophy, the two approaches are indispensable, but the serious problem is that the first approach absolutely is dominant, but the second is too weak. The correct choice of Chinese philosophy should be to let hundreds of flower bloom, to let different approaches compete with each other, and to cooperatively establish the prosperity of contemporary Chinese philosophy.

The debate on the yan-yi relation was carried out by Chinese philosophers collectively, and the principles and methods in the debate still belong to a living tradition of Chinese philosophy. From Yijing, Lunyu, Laozi and Zhuangzi to Wang Bi, "yi" which cannot be expressed fully by yan, is not only "idea" or "meaning" in the human mind, but is also some kind of ontological existence, which is beyond yan and emblematic symbols, and unspeakable. Thus, the debate on the yan-yi relation (...) refers firstly to metaphysics, secondly to moral philosophy, and then to epistemology and philosophy of language. Guided by this view, this paper recalls the source of the debate on the yan-yi relation to Yijing and Lunyu, distinguishes four meanings of "yi" in Chinese philosophy, and reconstructs three arguments. These arguments are the "yan cannot express yi fully" argument, "forget yan once you get yi" argument, and "yan can express yi fully" argument. Finally, this paper exposes and comments on those principles, methods and the general tendency shown in the debate from the following five aspects: starting point, value-preference, methodology, texts, and influences.
