This text explores the philosophical debate between Bradley and Russell concerning the nature of internal and external relations. Bradley followed the Leibnizian tradition, suggesting that all relations are intrinsic to a thing's concept, whereas Russell argued for their external nature. The author illustrates this conflict using the geometric example of a triangle. While a triangle is defined simply as a plane figure bounded by three lines, its numerous further properties—such as its centroid, inscribed circles, and the quantitative relationships between angles and sides—do not logically follow from this initial definition alone. Discovering these properties requires the introduction of new concepts that cannot be derived from the preceding ones. The text argues that concepts serve as cognitive tools, but they cannot yield further insights unless one moves beyond the definitions to the intentional objects themselves. Understanding thus involves a continuous expansion of the conceptual framework to grasp the internal relations that are inherent but not explicitly contained within the basic definition.
