Presentism is the thesis that everything is present, which implies that there are no past (or future) things or events. It is sometimes said to be imcompatible with the claim that every truth must have some ground on being. In this paper, I will examine the efficacy of such an argument in favor of presentism. In my view, however, how to respond to the grounding objection depends on what kinds of past truths we deal with: (i) truths about how present things were, (ii) general truths about things that no longer eixst, and (iii) singular truths about wholly past things. Before discussing this, I will also give an overview of the grounding project.

This paper discusses relationships between metatheory and discourse analysis in psychology. In order to explain a sense commonly held by discourse analysts, I described personal questions about own past psychological researches. It is a discontent with experimental and cognitivist tendency of traditional psychology and use of words as a topic of researches. Discourse analysis is an approach which is consisted of a set of epistemology, ontology, research questions, methodology and so on, so it is not a metatheory. Watanabe's (2010) metascientific basis in psychology were discussed, especially the one in metapsychological level was criticized from the discursive analytical viewpoint.

We can regard Russell's theory of classes in The Principles of Mathematics as a dual theory of classes based upon the distinction between a class as one and a class as many. In this paper, I shall show the following (A)-(D) from the viewpoint of how Russell dealt in the Principles with the paradox that bears his own name. (A) The dual theory of classes is one that deserves serious considerations. (B) Russell offered measures against the paradox other than the simple theory of types developed in an appendix to the Principles. (C) Russell avoided the paradox without forbidding self-memberships of classes in general. (D) Though introducing a hierarchy of types into pseudo-entities is a very important step to Russell's later theories (e.g., the substitutional theory and the ramified theory of types), we can find this strategy already in the Principles.

Time should be defined as the dimension of change because it passes. In this figurative talk, I believe, there is some truth that everyone should admit. In this paper, I aim to show what is behind the idea of time's passage, based on the presentist program originated by Arthur Prior, the founder of tense logic. For Prior, the presently existing things, and how they are, exhaust reality. Assuming this, he maintains that some statements may change in their truth-values since things, which those statements are about, do change in their properties. This is just what we mean by saying that time passes. I shall clarify and defend Prior's line of thought in the contemporary context of philosophy of time.

In this paper, I introduce three criteria for the historical assessment of research activities and apply them to mathematical activities, especially research activities in the set-theory. These criteria are accuracy, expressibility, and coherence. According to my proposal, a research tradition is progressive, when it is more accurate, more expressive and more coherent than its predecessors. A research tradition in a crisis is regressive with respect to at least one of these criteria. This approach is based on a nominalistic non-realism that is connected with a metaphysical position, namely the ontological theory of multiple languages.

A system of paraconsistent logic called PCL1 is known to have an interesting relation to Modal Logic S5, and in one of our previous papers, we focused on some concrete conditions to obtain the "minimal" extension of PCL1 enriched with the classical negation. Based on this result, the present paper offers some additional remarks on enriching PCL1 with the classical negation and other concrete conditions to obtain the relation between PCL1 enriched with the classical negation and S5. Also a simple relation between PCL1 and the existing systems is clarified and a maximal three-valued extension of PCL1 is presented.

In this paper, we present a logical system which is constructed on the following principles: I) the singular proposition is a universal proposition with a singular term as its subject; II) the identity proposition is a singular proposition with a singular term as its predicate; III) a singular term is a term which designates the only one object. The resulting system is shown to be inferentially equivalent to the original system of Lesniewski's Ontology dating from 1920. We shall present some results on the comprehension axiom and the law of extensionality, too.

We examined physical fitness adaptation after six weeks of snow shovelling using different types of shovels. Thirty-three subjects participated in this study and were divided two groups: normal shovel group and less-workload shovel (UD-shovel) group. Grip strength, vertical jump, 10 m obstacle walking, chair rising test, lactate threshold and body mass were measured before and after six weeks of snow shovelling. All measurements showed no significant differences between the groups. The chair rising test and ten meter obstacle walking were significantly at main effects. These values were higher in the after period than in the before period. But there were no significant differences at main effects in grip strength, vertical jump, lactate threshold and body mass. These results suggest that six weeks of snow shovelling may not affect upper body strength and aerobic capacity, but may affect lower body and muscle of trunk strength, power, agility, balance and coordination. These effects were not different if using normal shovels or UD-shovels.

In 1930, Einstein proposed the Gedankenexperiment that seems to show the invalidity of the time-energy uncertainty relation. Bohr gave an answer to this Einstein's challenge by resorting to the Einstein's general theory of relativity. However, many scientists and philosophers have critiqued his answer, and proposed new ones. The important proposals in these are ones given by Treder and Busch. In this paper, I survey and critique these answers. The point is how to interpret the time-energy uncertainty relation appeared in the Einstein's Photon Box. Next, I suggest a new answer to the Photon Box Gedankenexperment. My suggestion is that measurement of energy of phton is done by measuring the mass of box before and after the emission of photon.

"The enclosure of the mind" denotes a trend in the western thought history. It is a combined operation; how, where and in what the mind has been enclosed. Where is the place of the mind? -Our scientific common sense teaches us that it is in the individual brain. This represents a completed feature of "the enclosure of the mind". The opposite idea is the panpsychism, though, it would certainly be felt somewhat "fishy". Under this view, mechanisms such as communications from mind to mind should be natural, which would appear more doubtful. -This "fishiness" is an effect of "the enclosure of the mind" in the modern ages. There has been, however, no successful scientific proof of the "scientific common sense", yet. In a word, this is an opinion that the Zeitgeist has constructed, and the trustworthy appearance derives from the fact that it reflects the ground note of the modern world. In this article, this phenomenon is analyzed from three dimensions: <area system>, <human system>, and <spirit/material system>. They are in the thought history to form "Modern ages of the mind". Intertwined in the meanings, they are logically independent. These factors have produced an apparently bold new phenomenon. But, it can be analyzed as a revival of the traditional human-centrism and the rationalism that characterize the history of the West European thought.
