 Therefore, how a relation is represented is crucial in figuring out what follows from a relational state of affairs. Better representations will yield more “fruitful reasoning” and hence, will be more helpful for solving practical problems. It is obvious that in the paper Peirce intends to search for more desirable representations. Importantly, in section 4 when the third grade of clearness of the meaning “relation” is discussed, diagrammatic representation of relations makes its first appearance.
