Empirical Propositions and the Change of Language-Games

People unavoidably provide reasons for their words and deeds when reasoning in a language-game.Wittgenstein thinks that when people in different language-games argue with one other,they insist on adopting a doubtful attitude toward the reasons provided by the other side.His use of the term "language-game" here is a metaphor,and implies that people in different cultures can scarcely reason with one another.Indeed,according to Wittgenstein's consideration of concepts of logic in On Certainty,language-games are incompatible with one another because their internal logic and reasons are different from each other.However,in his discussion of empirical propositions Wittgenstein has also shown us the possibility that the intemal reasons of one language-game can transmit beyond its own borders and be valid in another language-game.     

Characterizing Simpler Recognizable Sets of Integers

For a given numeration system U, a set X of integers is said to be U-star-free if the language of the normalized U-representations of the elements in X is star-free. Adapting a result of McNaughton and Papert, we give a first-order logical characterization of these sets for various numeration systems including integer base systems and the Fibonacci system. For k-ary systems, the problem of the base dependence of this property is also studied. Finally, the case of k-adic systems is developed.

Conceiving Possibility： Kierkegaard and Zhuangzi

This paper examines two notions of possibility conceived by Kierkegaard and Zhuangzi respectively. Kierkegaard conceives of it with appeals to the feeling of anxiety, while Zhuangzi deals with it in terms of a type of aesthetic feeling. Based on these distinctions, the paper goes further to explore two types of human existence as fostered by these two corresponding concepts of possibility. According to Kierkegaard, in order to maintain a connection with possibility, which would provide freedom to human existence, one must have faith in the redeemer bringing back possibility so that an individual human being might renew his or her choice ceaselessly. Zhuangzi, on the other hand, advises staying in the realm of nothingness and letting go of all things to avoid being trapped by the struggle of discerning between good and evil.     

Towards a “Sophisticated” Model of Belief Dynamics. Part I: The General Framework

It is well-known that classical models of belief are not realistic representations of human doxastic capacity; equally, models of actions involving beliefs, such as decisions based on beliefs, or changes of beliefs, suffer from a similar inaccuracies. In this paper, a general framework is presented which permits a more realistic modelling both of instantaneous states of belief, and of the operations involving them. This framework is motivated by some of the inadequacies of existing models, which it overcomes, whilst retaining technical rigour in so far as it relies on known, natural logical and mathematical notions. The companion paper (Towards a “sophisticated” model of belief dynamics. Part II) contains an application of this framework to the particular case of belief revision.

Symmetric Propositions and Logical Quantifiers

Symmetric propositions over domain and signature are characterized following Zermelo, and a correlation of such propositions with logical type- quantifiers over is described. Boolean algebras of symmetric propositions over and Σ are shown to be isomorphic to algebras of logical type- quantifiers over . This last result may provide empirical support for Tarski’s claim that logical terms over fixed domain are all and only those invariant under domain permutations.

Why Freud and Jung Can’t Speak: A Neurological Proposal

This article provides a modern neurological explanation for the theoretical differences in psychoanalytic concepts and techniques between Freud and Jung. Specifically, the article contrasts their analytic skills as arising in the left and right brain, respectively. Modern neurological techniques reveal unique brain functions that explain many of the visionary and so-called mystic phenomena discussed by Jung. Many of his psychoanalytic concepts can be traced to right brain function. Modern research and philosophic analyses also provide light on Freud’s research method and its limitations.Barbara Stevens Barnum, RN, PhD, FAAN, former editor of Nursing Leadership Forum and Nursing & Health Care, is presently a writer/consultant. Before retiring, her positions at Columbia University included holding the directorship, Division of Health Services, Sciences and Education at Teachers College, where she also held the Stewart Chair in the Department of Nursing Education. Dr. Barnum has written in areas of nursing management, theory, education, and aspects of spirtuality/holistic nursing. Her books include: Nursing theory: Analysis, application, evaluation, Spirituality in nursing: From traditional to New Age, and The New Healers: Minds and Hands in Complementary Medicine.

What in the world are the ways things might have been?

Robert Stalnaker is an actualist who holds that merely possible worlds are uninstantiated properties that might have been instantiated. Stalnaker also holds that there are no metaphysically impossible worlds: uninstantiated properties that couldn't have been instantiated. These views motivate Stalnaker's "two dimensional" account of the necessary a posteriori on which there is no single proposition that is both necessary and a posteriori. For a (metaphysically) necessary proposition is true in all (metaphysically) possible worlds. If there were necessary a posteriori propositions, that would mean that there were propositions true in all possible worlds but which could only be known to be true by acquiring empirical evidence. Consider such a purported proposition P. The role of empirical evidence for establishing P's truth would have to be to rule out worlds in which P is false. If there were no such worlds to be ruled out, we would not require evidence for P. But by hypothesis, P is necessary and so true in all metaphysically possible worlds. And on Stalnaker's view, the metaphysically possible worlds are all the worlds there are. So there can be no proposition that is true in all possible worlds, but that we require evidence to know. In this way, the motivation for Stalnaker's two dimensional account of the necessary a posteriori rests on his denying that there are metaphysically impossible Worlds. I argue that given his view of what possible worlds are, Stalnaker has no principled reason for denying that there are metaphysically impossible worlds. If I am right, this undercuts Stalnaker's motivation for his two dimensional account of the necessary a posteriori.
