Concepts are equally core to causal theory, normative philosophy, and empirical description.

Evidence

Philosophers, lawyers, political and social theorists debate normative concepts such as democracy, justice, and human rights. Concepts are fundamental to description. For anthropology, ethnography, grounded theory, and similar methodologies, developing concepts is a core theoretical and empirical activity. Concepts are thus core in causal theories, normative philosophy, and empirical description. — Gary Goertz, Social Science Concepts and Measurement, 33
