This text explores the nature of thinking as a continuous process of experimentation based on the method of trial and error. The author argues that through thought, we project insights into the meaning of things using tools and assumptions specific to a given era. These assumptions are often unconscious and undergo constant transformation as a result of their practical application. A significant moment occurs with the discovery of new topics, which triggers shifts not only in terminology but also in deeper cognitive structures. The process of experimentation applies both to understanding objective reality and to searching for its inherent meaning, which transcends mere objecthood. The text emphasizes that cognitive tools are often formed tentatively and on trial, opening space for the constant revision of our understanding of the world. Overall, the reflection presents thinking as a dynamic, historically conditioned, and reflexive process in which conscious intentions constantly collide with unconscious assumptions in the search for a deeper sense of reality.
