Each of (a)–(c) exhibits a relation of dependence where a change in the independent variable y will result in variations in the dependent variable x. However, of the three examples cited above, normally only (a) and (b) are deemed relevant to philosophical discussions of relativism, for one main attraction of relativism is that it offers a way of settling (or explaining away) what appear to be profound disagreements on questions of value, knowledge and ontology and the relativizing parameter often involves people, their beliefs, cultures or languages.
