In the article, we undertook an analysis of the prospects described in the research literature in connection with overcoming the linear interpretations of time and the transition to the concept of multiple times. We argue that it is possible to link two relatively autonomous objects on the basis of which they are discussed: the sphere of historical knowledge and the theme of memory. We argue that, overcome at the level of theories of the historical process, the linear idea of time (...) is preserved at the level of the creation of national histories and finds its expression in ethnocentrism or methodological individualism. Overcoming ethnocentrism should be associated not so much with the search for a more balanced attitude to specific interpretations of the historical past, associated with the inclusion of injustice shown in relation to other peoples in their own national histories, but with the development of alternative concepts of time that constitute the very formats of writing stories. We believe that the prospects for overcoming linear interpretations of time are associated with the development of the theory of multiple times. We argue that the constructivist approach should be considered the most heuristic theoretical and methodological basis for its implementation. We believe that modern interpretations of the heterogeneity of time imply the recognition of the mobility of time boundaries between the past, present, and future. We put forward the thesis that the criterion for distinguishing the modes of time should be considered the difference in the formats of the organization of knowledge. Correspondingly, we offer an interpretation of the historical past in the format of historical experience. As one of the consequences of this thesis, we affirm the need to revise ideas about the forms of influence of the past on the present. We argue that the recognition of the theory of the heterogeneity of time gives rise to relativism in determining the significance of different time streams in different social groups and cultures. We believe that the recognition of the theory of the diversity of temporal flows for different social and cultural groups presupposes the implementation of a procedure for synchronizing the data of temporal flows, which, on the one hand, makes it possible to overcome relativism, and, on the other hand, allochronism. Furthermore, we emphasize that synchronization should be based on the concept of modernity, which in turn is built on the basis of the project of the future and thus allows for the selection of various ideas about time.

The action observation networks (AON) (or the mirror neuron system) are the neural underpinnings of visuomotor integration and play an important role in motor control. Besides, one of the main functions of the human mirror neuron system is recognition of observed actions and the prediction of its outcome through the comparison with the internal mental motor representation. Previous studies focused on the human mirror neurons (MNs) activation during object-oriented movements observation, therefore intransitive movements observation effects on MNs activity remains relatively (...) little-studied. Moreover, the dependence of MNs activation on the biomechanical characteristics of observed movement and their biological plausibility remained highly underexplored. In this study we proposed that naturalness of observed intransitive movement can modulate the MNs activity. Event-related desynchronization (ERD) of sensorimotor electroencephalography (EEG) rhythms, N400 event-related potentials (ERPs) component and corticospinal excitability were investigated in twenty healthy volunteers during observation of simple non-transitive finger flexion that might be either biomechanically natural or unnatural when finger wriggled out toward the dorsal side of palm. We showed that both natural and unnatural movements caused mu/beta-desynchronization, which gradually increased during the flexion phase and returned to baseline while observation of extension. Desynchronization of the mu-rhythm was significantly higher during observation of the natural movements. At the same time, beta-rhythm was not found to be sensitive to the action naturalness. Also, observation of unnatural movements caused an increased amplitude of the N400 component registered in the centro-parietal regions. We suggest that the sensitivity of N400 to intransitive action observation with no explicit semantic context might imply the broader role of N400 sources within AON. Surprisingly, no changes in corticospinal excitability were found. This lack of excitability modulation by action observation could be related with dependence of the M1 activity on the observed movement phase. (shrink)

The author elucidates the ontological basis of elementary mathematical theories and thereby assesses their certainty as a foundation for the more complex theories of modern mathematics, such as mathematical analysis and set theory. He adduces arguments in favor of the position of Frege, who held that geometry can provide a sufficiently broad and certain foundation for mathematics.
