„All relations are either qualitative or quantitative.“

—  Benjamin Peirce American mathematician 1809 - 1880
Context: All relations are either qualitative or quantitative. Qualitative relations can be considered by themselves without regard to quantity. The algebra of such enquiries may be called logical algebra, of which a fine example is given by Boole. Quantitative relations may also be considered by themselves without regard to quality. They belong to arithmetic, and the corresponding algebra is the common or arithmetical algebra. In all other algebras both relations must be combined, and the algebra must conform to the character of the relations. § 3.

„The general, and at the same time dynamic, type of analysis still remains an unwritten chapter of economic theory, the claims of innumerable “model-builders” notwithstanding... The … theoretical approach, based on the combination of the complexities of a general interdependent system with the simplifying assumptions of static analysis, constitutes the background of this investigation.“
