Concepts become multidimensional only when broken into secondary-level dimensions

Evidence

The next level down from the basic level is what I call the secondary level. For example, when we say that democracy consists of civil rights, competitive elections, and so forth, we are descending to the secondary level to give the constitutive dimensions of the basiclevel democracy concept. It is when we move down to the secondary level that the multidimensional character of concepts appears. The secondary-level dimensions form much of the ontological analysis of concepts. They also play a central role in causal mechanisms of various sorts. — Gary Goertz, Social Science Concepts, 83
