Instability and Contraction
Journal of Philosophical Logic. 2019. Vol. 48. No. 1. P. 155–188.
In other works, I’ve proposed a solution to the semantic paradoxes which, at the technical level, basically relies on failure of contraction. I’ve also suggested that, at the philosophical level, contraction fails because of the instability of certain states of affairs. In this paper, I try to make good on that suggestion.

We propose a test for abstract causal reasoning in AI, based on scholarship in the philosophy of causation, in particular on the neuron diagrams popularized by D. Lewis. We illustrate the test on advanced Large Language Models (ChatGPT, DeepSeek and Gemini). Remarkably, these chatbots are already capable of correctly identifying causes in cases that are ...

The language of filtrations and contractions is used to describe the class of G-varieties obtained as the total spaces of the construction of contraction applied to affine spherical varieties, which is well-known in invariant theory.
These varieties are local models for arbitrary affine G-varieties of complexity 1 with a one-dimensional categorical quotient. As examples, reductive algebraic semigroups ...

The article presents a comprehensive analysis of narratives about adulthood as an age identity and a period of life in the context of contemporary Russia. Particular attention is paid to the age group 40-60 years, which often finds itself on the margins of social research and policy. The study, conducted in a qualitative paradigm, includes ...

The article examines another round of destabilization in Somalia caused by conflicts amid territorial and economic disputes over Somali ports, as well as contradictions between federal and regional authorities. It is shown that the deal concluded in early 2024 between Ethiopia and unrecognized Somaliland led to a serious round of tension that threatened to escalate ...

The article defends the following theses: 1. The interpretation of relevant implication as a formalization of the natural concept of entailment leads to the fact that the logical properties attributed to the implication in a specific version of relevant logic are transferred to the level of semantics and determine the properties of the model. 2. ...

Emerging adulthood is the youth trajectory characterized by self-focus, identity exploration, feeling between adolescence and adulthood, instability, and experimentation. This trajectory was first identified in industrialized individualistic countries with gender equality and technological progress. To measure transition to adulthood, the Inventory of the Dimensions of Emerging Adulthood (IDEA) was created. Although emerging adulthood is considered ...

Gottfried Wilhelm Leibniz (1646–1716) was one of the great thinkers of the seventeenth and eighteenth centuries and is known as the last “universal genius”. He made deep and important contributions to the fields of metaphysics, epistemology, logic, philosophy of religion, as well as mathematics, ...

The expression “continental rationalism” refers to a set of views more or less shared by a number of philosophers active on the European continent during the latter two thirds of the seventeenth century and the beginning of the eighteenth. Rationalism is most often characterized as an epistemological position. On this view, to be a rationalist ...

We put forward a novel model for self-organized criticality in the dynamics of systems controlled by human actions. The model is based on two premises. First, without human control, the system in issue undergoes supercritical instability. Second, the subject’s actions are aimed at preventing the occurrence of critical fluctuations when the risk of control failure ...

В статье представлен анализ основных исследований концепции эффектуации, опубликованных в научных журналах за 1998-2014 гг. Выявлены этапы развития концепции, ключевые направления исследований эффектуации, а также те области анализа, в которых действие эффектуационной логики пока не изучено. Большинство исследований эффектуации носит концептуальный характер, базируется на построении теоретических моделей или представляют собой качественные исследования на основе изучения кейсов.

The article is devoted to the issue of compensation for pure economic losses under Russian law. The category of pure economic losses came into the focus of Russian researchers relatively recently. Currently, the mainstream discussion of Russian scholars on the topic is based on the analysis of foreign cases and arguments related to them. Meanwhile, ...

Within the broader literature on contextual determinants of effectual and causal cognitive logics, the paper explores the drivers of causal and effectual reasoning in student-founders of new ventures, particularly focusing on the role of university entrepreneurship-related offerings and student prior business experience. Using the Global University Entrepreneurial Spirit Students’ Survey (GUESSS), the study involves a ...

Studies examining the relationship between national culture and entrepreneurial activity have largely ignored the influence of culture on individual decisionmaking. Recent years have witnessed considerable interest in cognitive logics employed by entrepreneurs. A growing body of literature examines factors contributing to the relative reliance on causal and effectual reasoning as entrepreneurs attempt to launch and ...

We investigated the coalescence of nematic droplets in an isotropic environment and that of isotropic droplets in a nematic environment in quasi-two-dimensional geometry of a flat optical cell. Two different regimes of coalescence were found. In the circular meniscus between the nematic and isotropic regions both nematic and isotropic phases exist. As a result, two bridges form at ...

This study presents an agent-based model of capital markets by adopting simple trading rules for bounded rational agents who maintain different expectations regarding a tipping point at which price starts to change its direction from rising (falling) to falling (rising). The effect of herding behavior on the volatility of stock market prices and the rate ...

We adapt a polynomial-time approximation algorithm for computing the canonical basis of implications to approximately compute frequent implications, also known as exact association rules. To this end, we define a suitable notion of approximation that takes into account the frequency of attribute subsets and show that our algorithm achieves a desired approximation with high probability. ...

A continuous time model for multiagent systems governed by reinforcement learning with scale-free memory is developed. The agents are assumed to act independently of one another in optimizing their choice of possible actions via trial-and-error search. To gain awareness about the action value the agents accumulate in their memory the rewards obtained from taking a ...

Learning and adaptation play great role in emergent socio-economic phenomena. Complex dynamics has been previously found in the systems of multiple learning agents interacting via a simple game. Meanwhile, the single agent adaptation is considered trivially stable. We advocate the idea that adopting a more complex model of the individual behavior may result in a ...
