Michael Della Rocca, in his "Essentialism versus Essentialism", pointed out that Kripke's defense of his essentialism is made unstable by his limited use of the method of counterparts. But the defense, if trying to get out of this unstable position, would be circular, and therefore turns out to be unable to be justified. Kripke's version of essentialism, by introducing the method of counterparts into it, has a self-under-mining character, so argues Della Rocca. In this paper, I shall argue that these objections of Della Rocca to Kripke are wrong. After reviewing the objections, I shall argue that Della Rocca, when arguing for the circularity of Kripke's defense of his essentialism, is relying on a false premise and shall object to his objections. Then, I shall outline what more appropriate objections to Kripke's version of essentialism would be like.

This paper aims to update McTaggart's "contradiction" and to rethink the reality of time. According to McTaggart, every event has all of the incompatible A-characteristics. In other words, "past", "present", and "future" are both incompatible and compatible. This is McTaggart's "contradiction". I try to interpret this contradiction as follows: temporal becoming makes A-characteristics incompatible, while fixing them within description makes them compatible, and that temporal becoming and fixing them within description cannot help subsuming each other repeatedly. My interpretation suggests that this updated "contradiction" provides a proper reality of time (not unreality of time).

Richard Taylor claims that fatalism can be constructed out of the law of excluded middle. While allowing that his argument is clear and meaningful, I argue that the fatalism constructed from the law of excluded middle considers two different times to be logically independent. This implies that fatalism rejects the flow of time. Michael Dummett criticizes fatalism in terms of the difference between "change the past" and "bring about the past". His trial of the backward causation suggests the weakness of fatalism.

McTaggart has an insight that changes of property rely on changes of tense (McTaggart 1908). As I show in this paper, he fails to define A-series as a series for changes of tense, and therefore his proof for the unreality of time is unsuccessful. A-series found in the proof is reduced to a number of mere indexicals of time, and this reduction is pushed forward in Dummett's defense. My aim in this paper is not only to check the validity of their arguments but to investigate invincible difficulties faced in defining changes of tense. The latter is my main aim, and the former is a preliminary argument for it.

The denial of time is the foundation of European manner of thinking. History teaches us that Europeans have always tried to construct their World from self-identical beings which presuppose the denial of time. The most typical timeless beings are Platonic Ideas. Ideas descend from eternal World into the stream of time and make things what they are. Two kinds of time representations, B-series (earlier-later relation of moments) and A-series (past•present•future) are both devices for controlling actual time. Proofs of the Unreality of Time are essentially mere declarations of European manner of thinking. This author confirms the fact by examining proofs by Parmenides and McTaggart.

Scientific epistemology, which showed innovative developments in the last century, has been expected to involve various implications. Among other things, penetrating criticism of absolute truth to scientific theories is an important one. The concepts developed in relation with this knowledge skepticism include falsifiability, holism and theory ladenness. It looks, however, still sparse to develop their implications to research designs employed in usual research programs. This article attempts to provide five important requirements for obtaining evidences of high quality, and to discuss the relationship of these requirements with scientific epistemology. Special emphases are placed on how to cooperate for obtaining many individual scientific findings and also on how to take account of relativism in scientific researches.

It is thought that the problem of self-deception is difficult to treat because it includes a paradox. I investigate under what conditions self-deception occurs, rather than how the paradox is solved. I think one of the important conditions of selfdeception is that the two apparently contradicting beliefs coexist without either of them being unconscious. After surveying the discussions concerning whether self-deception is intentional, I focus on the role of "motivation", following Alfred Mele, and try to state the necessary and sufficient conditions of self-deception on the basis of the motivations and situa-tions of the self-deceivers.

The notion of truth conditions of sentences or psychological states plays important roles in various areas of philosophy, but authors who appeal to this notion rarely explain exactly what attribute of those entities truth conditions are. Indeed, there are two notions (not always clearly distinguished) that can legitimately be called the notions of truth conditions, and these are definable by reference to different semantical frameworks. It turns out that there is an important systematic relationship between the two notions, explicitly definable within Kaplan's theory of demonstratives, and this reveals that the two kinds of truth conditions are to be attributed to entities of different ontological types.

In this paper we intend to place the early Russell in the context of the refutation of idealism in the school of Meinong. We look into Mally's arguments against idealism, which have recourse to Russell's paradox, and Meinong's critique of them. Then we propose the hypothesis that the early Russell made up his thought in the Meinongian framework. From this point of view, we could point out that the origin of the paradox might be in the early Russell's criticism of Bradley's idealism. And Wittgenstein's resolution which could make Russell's theory of types dispensable might be compared to Mally's method of arguments which Meinong never adopts.

This paper is an attempt for clarifying what made Hume adapt such an obscure notion as sympathy in establishing the system of passions. In order to answer this question, it is necessary to see that his basic strategy in the Treatise is to hold the analogy between the two systems of the understanding and passions, and that sympathy is intended as the phenomenon in which this analogy is explicitly demonstrated.

The aim of this paper is to show that some form of direct realism concerning vision is false. Section 1 defines what it is to see things directly and identifies naïve realism as the target of criticism. Section 2 criticizes naïve realism by arguing that we cannot phenomenally be conscious of three dimensional shapes of physical objects, and also explains how we see physical objects and why we are naïve realists before starting philosophical thinking. The final section concludes with some remarks about the character and limits of my argument against direct realism.

In this paper I focus on the roles of proprioception and of perception in forming the cognitive picture of ourselves as physical agents in the world. Our proprioceptive awareness is plausibly characterized in terms of its distinctive epistemic unmediatedness and constancy, and this fact may seem to support the view that the primary core of our self-conception is constituted by our proprioceptive self-awareness, not by ordinary modes of self-perception. I criticize some main arguments for this view, and suggest that the proper understanding of the significance of proprioception needs the appreciation of its intricate involvement with our perceptual bodilyawareness. I conclude with the remark that the notion of basic action should be restored on this epistemological footing.

In speech act theory, there has been a tendency to concentrate investigations on the single utterance of a sentence. In my opinion, this tendency seems to originate based on a tacit and unproven premise: namely, an illocutionary force should dwell in each single utterance. In this paper, first, I take up the texts of Austin and Searle as examples, and try to show how this premise was smuggled into the theory. Then I argue that there are cases where we do an illocutionary act not by making a single utterance, but by making a group of utterances ("conversational sequence"). Through these examinations, I conclude that the premise in question is to be replaced by an alternative one: Sometimes-or maybe fundamentally -an illocutionary force dwells in a conversational sequence.

This paper deals with the question of why intentional vocabulary is distinctive. The question arises from the comparison of the status of normative discourse in the philosophies of W. Sellars and of W. V. Quine. While Sellars gives a significant role to normative discourse, Quine does not. I call into play Bjφrn Ramberg's attempt to combine insights of R. Rorty and of D. Davidson to herald the emergence of what he calls a post-ontological philosophy of mind. Ramberg makes it clear that Rortian pragmatism has every reason to accept openhandedly Davidson's claim of the distinctiveness of intentional vocabulary. On the basis of Ramberg's achievement, I conclude that Sellars's position is more productive than Quine's.

W.V.O. Quine's relation with nominalism is complicated and controversial. In one context Quine has been attacked for being "nominalistic", while in another context he has been attacked for not being "nominalistic". Furthermore, Quine considered himself to have abandoned his early "nominalistic" views, but those who attack him for being "nominalistic" do not overlook his conversion.In this paper, I first clear up the misconception about Quine and his association with "nominalism". Then I point out the genuine problems of Quine's nominalism. Finally, I suggest several ways to solve those problems. The solution recommended in this paper is the one suitable for the sailors of Neurath's ship.

Against the prevalence of the social construct view that the concept of a person is a social artifact like that of a nation, most notably David Wiggins offers a more naturalist alternative. He compares "person" to a natural kind term as it is elucidated according to the theory of direct reference, and restricts in effect the extent of personality to the animal kingdom. In this paper I shall examine his proposal and argue for an intermediate position; the concept of a person is much closer to a natural kind concept than social construct theorists maintain, but not so close as Wiggins suggests. Indeed, the social constructionism and Wiggins's naturalism are just two consequences of the untenable ontological dichotomy of natural things as real and artifacts as nominal. A better understanding of the concept of a person requires much deeper appreciation of the reality of natural-cum-artifactual kinds of things.

This paper deals with C. Wright's strategies to establish Frege's logicism. They essentially depend on Frege's Theorem (FT), i.e. the derivability of Peano-Dedekind axioms from the second-order logic plus Hume's principle (HP). HP says that the number of the concept F is identical with that of G if and only if F is equinumerous with G. By regarding HP as the explanatory principle of the number of a concept, Wright seems to assert that FT has already shown that Frege's logicism has been completely established. On the contrary, Frege regarded HP as unsatisfactory for establishing the foundations of arithmetic. It is powerless to decide whether the number of the concept "not identical with itself" is the same as Julius Caesar. This problem is called Julius Caesar problem (JC). Thus if Wright were right, historical Frege would have been rashly convinced that HP alone would not resolve JC, so that there had been no problem such as JC. I think, however, that JC is a genuine trouble to Frege's logicism and then Wright's strategies do not establish it.

Wittgenstein was intrigued by the idea of experiments where subjects see their own body through mirror or screen, and move their body relying solely on that visual information. But it is not so clear why such experiments are so important and what they are supposed to show. In this paper I argue that such experiments reveal our naive conception of the relation between intention and body, which is based on two specific models; namely, criticize both of them, and draw some alternative pictures.

A state function which describes some quantum phenomenon includes two types of information in a mixed form: the information on the probabilistic behavior and also on the physical state of the system. The aim of this paper is to show that it is possible to separate the probability information from the description of a quantum process. This is done by applying the consistent history method by Griffiths, Omnes, GellMann, and Hartle to the path-integral formulation. The remainder should be an elementary physical process, the realization of which presumably obeys the law of probability.

The recent anti-Lockean Animalists hold that the so-called problem of personal identity is a matter of persistence of a living organism and charge the traditional Lockean view with some ontological puzzles as to how we can be a kind of animals. This newcomer proposal, however, makes it difficult to understand the importance of our distinctive psychological nature, and results in analogous puzzles about the relation between an animal and its body. The problem is to bridge the gap between the mental and the biological so as to make an entire picture of ourselves, i.e. persons as a kind of animals essentially endowed with affluent psychology. A promising solution is to abandon the reductionist assumption prevalent in this controversy and to accept our persistence as primitive relative to both the psychological and the biological continuities.
