## Summary

In "Information, Computation, Cognition. Agency-based Hierarchies of Levels," Gordana Dodig-Crnkovic delves into the concept of nature as an informational structure with computational dynamics, known as info-computationalism. The paper argues that an info-computational agent is essential for the potential information of the world to actualize. By defining information as the difference in one physical system that makes a difference in another physical system and drawing from Bateson and Hewitt's definitions, Dodig-Crnkovic establishes natural computation as a computational model of the dynamics of the physical world. This model suggests that information processing is constantly occurring on various levels of organization. The framework presented in this paper sheds light on the intricate relationships between computation, information, agency, and cognition within a common conceptual framework. This perspective holds particular significance for fields such as biology and robotics where understanding how information is processed and utilized can lead to advancements in artificial intelligence and biological systems. By emphasizing the role of info-computational agents in shaping our understanding of nature's informational structure and computational dynamics, Dodig-Crnkovic highlights the importance of considering these factors when studying complex systems in both natural and artificial contexts.
