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 contemporary ecological literature, the instrumental approach to nature is convincingly discredited and it is acknowledged that man's goals and the means for achieving them must be brought into accord with ecological demands. Moreover, the spiritual importance of nature for man is recognized: through contact with nature man can be morally improved. Ecological knowledge acquires a moral coloration and significance; the philosopher merely has to reveal and analyze the intellectual foundations of this knowledge, formulate by relying on them the (...) general principles of an ecological ethics, and then draw from them standards and rules for human behavior, the criteria for what is inadmissible and for what must be from an ecological as well as a moral perspective. In a word, knowledge obliges. (shrink)

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.

The article examines the controversy between the “orthodox” Indian philosophical school Vaiśeṣika and one of the greatest Buddhist philosophers - Vasubandhu on the existence of subject as a reality. The discussion is investigated on the example of the text “Pudgalaviniścaya”. PV of Vasubandhu - literally “Study on the Self”, or “pudgala” - is traditionally considered the 9th chapter of “Abhidharmakośabhaṣya” of the same author and is one of the most important polemical treatises on the self, or ātman, in Buddhist philosophy. (...) Among the issues discussed are the famous “epistemological argument”, the ability of recall and perception, how a difference between moments of consciousness is possible, whether the substrate for consciousness is necessary. One of the strategies of Vasubandhu is that he tries to find internal contradictions in the arguments of opponents. We can say that the main argument of Vasubandhu is aimed at justifying the mechanism of the cause-and-effect occurrence of all phenomena. If the Vaiśeṣikas proceed from their logic about the need for a substance for qualities, then Vasubandhu tries to persuade them to his side and offer a fundamentally new explanatory model, according to which there are only sequence-like moments-phenomena that flow from each other according to the law of cause and effect.

Confucianism defined benevolence with “feelings” and “love.” “Feelings” in Confucianism can be mainly divided into three categories: feelings in general, love for one’s relatives, and compassion. The seven kinds of feeling in which people respond to things can be summarized as “likes and dislikes.” The mind responds to things through feelings; based on the mind of benevolence and righteousness or feelings of compassion, the expression of feelings can conform to the principle of the mean and reach the integration of self (...) and others, and of self and external things. The “relations between the seven kinds of feelings and the Four Commencements,” however, was not developed into a theoretical idea in Confucianism. After Confucius, the relationship between the universality of natural sympathies and the gradation of love for relatives gradually became an important subject in Confucian ideas of benevolence and love. By “refuting Yang Zhu and Mozi,” Mencius systematically expounded on this issue. Love had two ends: self-love and natural sympathies, between which existed the love for relatives. These two ends were not the two extremes of Yang’s self-interest and Mozi’s universal love. Love for relatives not only implied a gradation, but also contained universality and transcendence that came from self-love. Love for relatives, natural sympathies and self-love had a kind of tension and connectivity between two dynamic ends. The Confucian idea of benevolence and love hence demonstrated differences and interconnectivity. An accurate understanding of such “feelings” and “love” is important for us to grasp Confucian thoughts on benevolence and its realization. (shrink)

We define $\Psi $ -autoreducible sets given an autoreduction procedure $\Psi $. Then, we show that for any $\Psi $, a measurable class of $\Psi $ -autoreducible sets has measure zero. Using this, we show that classes of cototal, uniformly introenumerable, introenumerable, and hyper-cototal enumeration degrees all have measure zero. By analyzing the arithmetical complexity of the classes of cototal sets and cototal enumeration degrees, we show that weakly 2-random sets cannot be cototal and weakly 3-random sets cannot be of (...) cototal enumeration degree. Then, we see that this result is optimal by showing that there exists a 1-random cototal set and a 2-random set of cototal enumeration degree. For uniformly introenumerable degrees and introenumerable degrees, we utilize $\Psi $ -autoreducibility again to show the optimal result that no weakly 3-random sets can have introenumerable enumeration degree. We also show that no 1-random set can be introenumerable. (shrink)

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.

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.

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.
