The text explores the relationship between the concept and theory, specifically focusing on the conceptual framework within geometry. It addresses the problem of logical connections between geometric figures that are otherwise intended as isolated entities. Although a figure like an equilateral triangle maintains its validity regardless of size or other instances, geometry as a theory cannot exist without the support of a logical context. The author argues that concepts cannot be understood or defined in isolation, as every definition relies on a network of other concepts. A fundamental distinction is made: definitions pertain to intentional objects rather than the concepts themselves. We possess limited knowledge of concepts as such and can only intuitively compare them through logical contexts. Furthermore, any attempt to precisely delineate the content or scope of a concept forces a transition from the realm of conceptualization to the realm of intentional or real objects. The passage thus highlights the inherent difficulty in grasping the nature of concepts directly, emphasizing their functional role within logical reasoning and theoretical structures.
