Understanding a proposition for an intelligent agent is an important epistemic concept. We first discuss intuitively general logic characteristics of understanding, and give a language and a semantics containing understanding as a modal operator. Secondly, we develop the system LU for the operator, give some results of its proof theory, and then we prove the frame soundness and frame completeness of LU.

We construct a Hilbert style system RPL for the notion of plausibility measure introduced by Halpern J, and we prove the soundness and completeness with respect to a neighborhood style semantics. Using the language of RPL, we demonstrate that it can define well-studied notions of necessity, conditionals and propositional identity.

Evaluative studies of inductive inferences have been pursued extensively with mathematical rigor in many disciplines, such as statistics, econometrics, computer science, and formal epistemology. Attempts have been made in those disciplines to justify many different kinds of inductive inferences, to varying extents. But somehow those disciplines have said almost nothing to justify a most familiar kind of induction, an example of which is this: “We’ve seen this many ravens and they all are black, so all ravens are black.” This is (...) enumerative induction in itsfullstrength. For it does not settle with a weaker conclusion (such as “the ravens observed in the future will all be black”); nor does it proceed with any additional premise (such as the statistical IID assumption). The goal of this paper is to take some initial steps toward a justification for the full version of enumerative induction, against counterinduction, and against the skeptical policy. The idea is to explore various epistemic ideals, mathematically defined as different modes of convergence to the truth, and look for one that is weak enough to be achievable and strong enough to justify a norm that governs both the long run and the short run. So the proposal is learning-theoretic in essence, but a Bayesian version is developed as well. (shrink)

In the article the socio-political and socio-economic processes of the modern post-industrial society and the possible prospects of its future are analyzed. Existing at this moment concepts of the historical process, in particular, formational, civilizational, theories of modernization, do not provide an adequate analysis of the processes taking place in society. Thus, according to the theory of local civilizations, the basis of civilization are unique cultures that are resistant and incapable of self-transformation. However, the modern world is an expansion of (...) multiculturalism. After the collapse of the socialist system the formational theory is discredited in public opinion. However, some of the provisions of this theory remain relevant. The theory of modernization is not universal and it is used in some cases of social researches. At the same time, the author does not share the point of view expressed by Samuel Huntington about the nature of the conflicts taking place in the world as a clash of civilizations. The article suggests that the essential processes taking place at the end of the 20th - the beginning of the 21st century in the world, linked to two factors. The first factor is change in the political map of the world, redrawing of borders, change in the political balance of power. The second factor is more significant. It is the aging of formational changes which nature remains open. But their focus will be directly determined by common culture, state of public consciousness and spiritual development of society.

The psychological state and neural correlates of 19 women undergoing normal childbirth were studied. Frequent occurence of nonordinary psychological phenomena was traced back in 6 subjects, occurring in active and passive alertness, as well as hypnagogic/hypnopompic periods, and in dreaming, during the late period of pregnancy, giving birth, and the period of 2-4 days post partull. The brain activity of the aforementioned subgroup during this time was characterized primarily by general activation of the right hemisphere in the bandpass of infraslow (...) electrical processes and by more localized EEG activation. The implications of the data for research on gender-specific altered states of consciousness are discussed. (shrink)

We would like to thank an anonymous referee for his helpful comments on a previous version of this paper.

The topic of time is central to Levinas's philosophy. By examining aspects of the Biblical stories of Abraham and Moses compared with Greek myths, mainly that of Cronos devouring his children, this paper aims to show that Levinas's view of time, though certainly indebted to the Greek (i.e. philosophical) tradition, contains traces of Biblical experiences. Moreover, Levinas's interpretation of time will serve as a concrete demonstration of the way the Jewish experience enables Levinas to express his criticism of the philosophical-Greek (...) tradition.

The article analyzes the theoretical foundations of the modern project of rational ethics, in which the ethics of discourse is interpreted as a critical theory of society and a critic of modern morality. I. Kant was one of the first to offer the possibility of generalizing the norms of morality and perception of ethics as a transcendental critique of morality. Neo-Kantianism develops ethics as the most important part of the philosophical system and fixes its scope by the idealistic theory of (...) morality. In Russian philosophy, modern ethics is perceived as a normative theory that has to do with issues of self-determination, moral regulation, and freedom of choice. The origins of discourse ethics in the philosophy of the 20th century go back to the “pragmatic turn” and to vigorous discussions about hermeneutics of language and its a priori status in German philosophy, and in analytical philosophy regarding the understanding of metaetics. The modern program of ethics of discourse receives meaningful justification as the logic of moral argumentation in the social philosophy of J. Habermas and in the transcendental pragmatics K.-O. Apel. The ethics of discourse is born from the real need to justify moral requirements and norms. Ethics as a critique of moral argument is associated with the pre-reflexive horizon of the life world, why it is a deontological, formalistic and universal ethics. Two significant projects of discourse ethics, presented in the article as an analysis, should be defined as “weak and strong” variants of philosophical transcendental idealism in modern science.
