The Nature And Significance Of Economic Science by Lionel Robbins

Defines economics as the study of human behavior in allocating scarce means among competing ends, emphasizing choice under scarcity and the logical, deductive analysis of such decisions. Distinguishes positive inquiry from value judgments, defends ordinal utility and rejects interpersonal utility comparisons, and adopts methodological individualism. Clarifies the scope and limits of economic reasoning and its separation from technological and ethical considerations.
