This text presents a modified concept of the monad, departing from the classic Leibnizian definition by emphasizing its interaction with the surrounding world. The author proposes that monads should not be understood as closed entities, but as subjects possessing not only windows for observation but also doors for active external engagement. The key concepts introduced are externalization and internalization. Externalization describes the process where a monad's internal activity transcends its boundaries to influence surrounding events. Conversely, internalization represents the intake of external stimuli and information back into the interior, including reflection on the consequences of the monad's own actions. The text emphasizes the necessity of investigating the specific modes of these transitions between the interior and exterior. Through this approach, the monad is transformed from an isolated point into a dynamic element in a constant creative and informational relationship with its environment and other monads. This redefinition allows for a deeper understanding of the relationship between individual subjectivity and objective reality through the mechanisms of mutual interaction.
