Normative dualism is found in philosophies that may be strikingly different from

philosophies. See list below of several features of normative dualism.
1. The terms require each other for their meaning. They can only be understood
by contrast with each other.
2. One term is the superior of the other, in a variety of senses.
3. The terms are asymmetrical, even though they are frequently claimed to be
merely descriptive of differences. Note that, while the superior term usually implies a
norm or standard, the inferior term may appear to be merely descriptive.

superior term -- something they will be willing to take credit for being, or attaining.
5. These related terms can be used by those associated with the superior term
