Abstract
The aim of our paper is to present a project within the dynamics of knowledge as an extension of Roman Suszko’s diachronic logic. A hierarchical system of knowledge can be seen as a toolkit for philosophical study in some aspects of the dynamics of knowledge, especially scientific knowledge. They can also be considered as models of rationality – they help to describe and analyze historical and sociological aspects of the dynamics of knowledge by means of formal methods. The project shares some connections with the following conceptions: the semantic epistemology of Kazimierz Ajdukiewicz, the diachronic logic of Roman Suszko, and the historical epistemology of Jerzy Kmita. Three main situations are investigated – a perfectly normal situation, the situation of constraint, and that of exasperation. These situations were introduced by Leszek Nowak in the framework of non-Marxian historical materialism. Our approach results in models for such fundamental processes as innovation, development, and advancement as composed of three strictly axiological concepts. Also, we consider going beyond rationality and rational values. Therefore, we are interested particularly in the irrationality and counterrationality of scientific change. Finally, through a pragmatist approach, we can cope with responsibility within social structures.
