The goal of the research is to elaborate integrative approaches which allow adopting different dynamic theories of rationality and outlining the ways of the construction of the general theory of rational action.
The research methodology includes actual trends in logic and computer science that are directed to formal analysis of interactive intellectual systems. Moreover, it refers to the methods of analytic phenomenology, postructuralism, theory of argumentation, theory of speech acts, actor-network theory, neo-Gricean pragmatics.
The main theoretical and methodological results of the research are:
- There were elaborated logical and epistemological models of individual and collective intentionality, cooperative activity and rational dialogue. As a result of the systematic analysis of different types of rationality in communication, classical dichotomy of the act-rationality and the rule-rationality was supplemented with the goal-rationality. There was given the interpretation of the strategic exposures of the design of logic norms as the mistakes of collective we-intentionality. The modification of the Searle`s formal definition of intentionality was proposed. This modification permits the elaboration of the model of artificial intelligence model in the framework of first-order logic. The algebraic model of the dialogic approach to systematization of non-classical truth-values was constructed. Furthermore, the algebraic interpretation of the concept of ‘negation’ in Heraclitus and Nagarjuna was provided in terms of this model. There was given the reconstruction of the dispute between Protagoras and Euathlus as a practical argumentation with a fake opponent. Moreover, the ontological approach to coherent deontology was elaborated. The pragmatic functions of compositionality and non-compositionality in intellectual interactions were revealed.
- The explicative potential of the game theory as the general theory of rational behavior was approved. The productivity of the game-theoretical approach to the problem of demarcation between semantics and pragmatics was shown. Furthermore, there was given the game-theoretical model of the refereeing in football. The referee was considered as a player who cannot be replaced by technical tools. The formal model of the relations between collective and individual obligations was elaborated in the framework of game-theoretical approach to deontic logic. Besides, there was given the formal model of global and local balance in international relations.
- There was given a comparison between logical and psychological approaches to rationality modelling. Further, the preconditions for the development of hermeneutics of action as a part of logics in the works of B. Keckerman and as a mathematical modelling of social relations by N. Condorcet were made explicit. The archival data available from CHSP (Centre d’histoire de Sciences, Paris) were used to create a reconstruction of the project of psychological foundation of logic by G. Tarde
- There was given an evaluation of the models of rationality for a number of cases in the history of philosophy and sciences. In the one case, it was shown that there is a continuity between the accounts of intentionality of P. d'Аilly and of W. Ockham. The other case reveals the antinomies of Nietzschean interpretations of antique and modern rationality. The third case shows the way to understand the concept of the project and the projective activity itself via M. Heidegger’s triple foundation theory. The fourth case compares anthropological model of rationality of B. Latour and sociological model of R. Collins, it traces the connection between key paradoxes of modern rationality and Latour’s claim about “false consciousness” of actants. The fifth case provides evidence on the key role of interpretation in H. Putnam’s model of rationality. The sixth case gives the analysis of pragmatist’s roots of the D. Kaplan’s theory of rationality of religious activity. The seventh case shows the prospects of phenomenological and transcendental-pragmatic approaches to modelling limited rationality. The eighth case elaborates basic methodological principles of the teleological theory of action and provides criticism of the standard causal theory of action.
- There was given an analysis of methodological foundations of postnonclassical scientific rationality. Postnonclassical methodology of transdisciplinarity had been compared with a nonclassical methodology of interdisciplinarity. This comparison then helped to refine some consequences of Bayesian revision of scientific rationality for the objectivist’s ideal of scientific methodology. The conceptual apparatus of universal logic made it possible to arrange systematically a wide variety of meta-logical and meta-metalogical monism and pluralism.
The research results are reflected in 25 articles of participants and partners of the project that were published in English in the collection of scientific papers «Rationality in Action: Intentions, Interpretations and Interactions» (ed. Dragalina-Chernaya, E., Saint-Petersburg: Aletheia, 2015). The project has also resulted in a number of articles that are published or are in print: 6 articles in English and French in foreign peer-reviewed journals (including 2 articles in journals indexed in the Scopus quartiles 1-2, and/or Web of Sciences), 2 chapters in English monographs published by the publishing house from a B category in the SENSE Ranking of academic publishers; 3 articles in Russian journals from the list of VAK; 3 articles in Russian journals indexed in RSCI; 2 articles in the collections of scientific works.
The international conference «Rationality in Action: Intentions, Interpretations and Interactions» with the participation of all participants of research, including undergraduate and graduate students, as well as foreign and Russian project partners from the universities of Nijmegen and Groningen (Netherlands), University of Sorbonne (Paris-IV) and Caen (France), Moscow and St. Petersburg State University took place during October 26-27, 2015. The participants of the research presented papers at the 5th World Congress on universal logic «UniLog-2015» (Istanbul), at the conference «LNAT3: The semantics and pragmatics of logical constants» (Brussels), at the conference «The Tree of Knowledge: Theories of Sciences and Arts in Central Europe, 1400-1700» (Warsaw), at the conference «The typology of cultures and the problem of cultural memory» (Moscow State University), at the conference «XVI April International Academic Conference on Economic and Social Development», and on the theoretical seminars of HSE.
The methodological and theoretical results obtained in the research were included in the university courses on logic, ontology, epistemology, history of philosophy, formal and experimental pragmatics, and ethics, in course papers and in MA and Ph.D. thesis.
