The article tells us about well-known physical problem of whether ether substance to be available. Albert Einstein sum up this question by his theory of relativity, arguing there are no ether substance at all. But many physicians there has been facing difficulties that were evidence of the real presence of ether. This accords with the main idea of many oriental spiritual and physical practices such as yoga and chi-kung, as well as of modern theory of non-linear thermodynamics.

The article reveals the problem of the ultimate base of cognition as one of the most important since formation of gnoseology and actual in the modern philosophy. The conclusion is drawn that, despite the logic uncertainty, the analysis of a problem of the ultimate bases of knowledge represents methodologically valuable criterion of true. Thus use of the given criterion probably only at synthesis of logic and anthropological aspects that assumes unity of sensual, rational and intuitive ways of knowledge. It allows (...) avoiding the conflict of theory of knowledge and psychology while decision of a problem of the ultimate bases, preserving scientific principles of objectivity and consistency.

The purpose of the article is to research the unseparable connection between objective aspects of cognition linked with metodology and logic and subjective ones which are covered to the subject’s mind and world outlook. According to psychology such a connection directly influences on understanding of truth and can be considered in the problem of artificial intelligence.

The article is about one of the vital problem for analytic philosophy which is how to define truth value for sentences which include their own truth predicate. The aim of the article is to determine Saul Kripke’s approach to widen epistemological truth to create a systemic model of truth. Despite a lot of work on the subject, the theme of truth is no less relevant to modern philosophy. With the help of S. Kripke’s article “Outline of the Theory of Truth” (...) and R. L. Kirkham’s work “Theories of Truth: A Critical Introduction” the author tried to represent a non-classical approach which is now known as Saul Kripke’s truth value gaps theory. Considering his solving of the Liar Paradox, as well as the Strenghened Liar, it is obvious that there could be the circumstances (or facts) that make sentences have no truth value. In that case the solving of the paradox attracts Kleene’s non-classical three-valued logic which contains the third way and the solution falls into the gap between truth and falsity. Hence there are no relevant and full satisfactory ways to solve the Liar’s Paradox by the language-levels ap- proach. The task consists in an extension of the approach to natural languages and elimination of an ad hoc element as well. Besides that, the language-levels approach refers to the speaker that means that only the last one is allowed to define the hierarchy of the levels and truth value of sentence, but often he does not know what level he is speaking of. As Kripke stated, contingent facts can lead to a paradox which isn’t allowed for a logical point of view. However usage of mathematical apparatus allows the theory in question to be universalized and moreover paves the way to futher epistemological develop- ment of the problem in question. As Kripke’s theory is formalized and presented as a functional series, it gives access to a system model of truth whose elements would be epistemological theories (concepts) of truth. Such a model, for instance, confirms the validity of the deflationary concept of truth. Refs 7. (shrink)

Kirkham’s book is not a plain attempt of asking the questions like ‘What is truth?’ since it would, according to him, be one more mistake followed by confusion. The components of this four-dimensional confusion (vagueness, ambiguity, several ways of describing the same project, and one answer for two distinctly different questions about truth) find its original explanation in Kirkham’s book. Having stated that all of the previous theories of truth were just irrelevant to the question of “What is truth” because (...) when asking different questions about truth, he draws his non-trivial approach of assigning each theorist to the particular question (or ‘project’) he or she was trying to answer with his or her theory of truth. So, the main merit of Kirkham’s work is the clarification of this most urgent philosophical problem of truth on the way of metaphysics. (shrink)

The article provides a linguophilosophical analysis of theoretical approaches to the symbolism of Vyacheslav Ivanov and Andrei Bely using the predicative concept of Lyudmila Gogotishvili. It is shown that the consideration of the category of symbol in the dimensions of the unmanifest and the manifest makes it possible to expand the problematics of symbolism into phenomenological and linguophilosophical perspectives. In this case, symbolization turns out to be associated with reference, determined by the specifics of the “participation” in it of the (...) linguistic subject and predicate and the status of the referent as a phenomenon of consciousness. The antinomy of the unmanifest and the manifest presupposes in symbolic reference the allocation of a special extra-linguistic category of the most real, which is fundamentally outside the field of natural language and is energetically associated with it through verbal myth. It is shown that the ratio of myth, name and the most real in the reference allows using Gogotishvili’s predicative concept to evaluate the linguophilosophical features of this or that approach to the symbol. It is concluded that the symbolism of Vyacheslav Ivanov presupposes the prevailing role of the predicate in the reference to the unmanifest most real and can be designated as mythological, while the symbolism of Andrei Bely presupposes the prevailing role of the subject in the reference to the real, manifested in language, and can be designated as metaphorical.

We analyze a game between three players: two Athletes and an Inspector. Two athletes compete with each other and both may cheat to increase their chances of victory. The Inspector wishes to detect incidents of cheating, and performs tests on athletes to detect cheating. The test is costly for the Inspector. Both probability of cheating and that of testing decrease as cost of inspection diminishes.

Looking for goal-relevant objects in our various environments is one of the most ubiquitous tasks the human visual system has to accomplish. Visual search is guided by a number of separable selective-attention mechanisms that can be categorized as bottom-up driven – guidance by salient physical properties of the current stimuli – or top-down controlled – guidance by observers' “online” knowledge of search-critical object properties. In addition, observers' expectations based on past experience also play also a significant role in goal-directed visual (...) selection. Because sensory environments are typically stable, it is beneficial for the visual system to extract and learn the environmental regularities that are predictive of the target stimulus. This perspective article is concerned with one of these predictive mechanisms: statistical context learning of consistent spatial patterns of target and distractor items in visual search. We review recent studies on context learning and its adaptability to incorporate consistent changes, with the aim to provide new directions to the study of processes involved in the acquisition of search-guiding context memories and their adaptation to consistent contextual changes – from a three-pronged, psychological, computational, and neurobiological perspective.

In the contextual cueing task, visual search is faster for targets embedded in invariant displays compared to targets found in variant displays. However, it has been repeatedly shown that participants do not learn repeated contexts when these are irrelevant to the task. One potential explanation lays in the idea of associative blocking, where salient cues block the learning of invariant associations in the task-irrelevant subset of items. An alternative explanation is that the associative blocking rather hinders the allocation of attention (...) to task-irrelevant subsets, but not the learning per se. The current work examined these two explanations. In two experiments, participants performed a visual search task under a rapid presentation condition in Experiment 1, or under a longer presentation condition in Experiment 2. In both experiments, the search items within both old and new displays were presented in two colors which defined the irrelevant and task-relevant items within each display. The participants were asked to search for the target in the relevant subset in the learning phase. In the transfer phase, the instructions were reversed and task-irrelevant items became task-relevant. In line with previous studies, the search of task-irrelevant subsets resulted in no cueing effect post-transfer in the longer presentation condition; however, a reliable cueing effect was generated by task-irrelevant subsets learned under the rapid presentation. These results demonstrate that under rapid display presentation, global attentional selection leads to global context learning. However, under a longer display presentation, global attention is blocked, leading to the exclusive learning of invariant relevant items in the learning session. (shrink)
