This text deals with the philosophical reflection on the concepts necessary for properly grasping and thinking about reality. The author proceeds from the assumption that understanding reality requires specific means and methods, with adequate concepts serving as the primary instruments. The main focus is on the need to clarify the term 'reality' itself through an analysis of the verb 'to be' and its various linguistic derivatives, such as entity, being, or temporal aspects of existence expressed through terms like pastness and futurity. The text emphasizes that for effective engagement with reality, it is first necessary to define word meanings precisely and establish rules for further mental operations. Although it is an unfinished fragment, the outlined methodology suggests a profound interest in ontological and terminological clarity. The work thus serves as a theoretical introduction to a deeper investigation of the structures of human thought in relation to the surrounding world and its essence. The author highlights the interconnection between the choice of a conceptual apparatus and the resulting ability to interpret facts.
