Abstract
Nineteen thoughtful essays devoted to the theoretical aspects of sociological investigation: the use of ideal types, the causal concept and the concept of social change, functional analysis, the formalization of theory, and the place of values in sociology. C. Wright Mill's "On Intellectual Craftsmanship" is an engaging and informal account of how one social scientist goes about his business, with a liberal sprinkling of criticisms against the tendency to divorce methodological inquiry from the scientific investigation itself. --L.
