Abstract

This chapter focuses on one of the common fallacies in Western philosophy called the subjectivist fallacy (SbF). The SbF occurs when one concludes that something is true for one person (a subject) but not true for another person (another subject), when, in fact, it is true objectively for all persons. SbF is a fallacy of relativism. Relativism, in general, means the truth‐value of a judgment is neither necessary nor universal; however, there are multiple kinds of relativism. SbF is not only a fallacious depiction of relativity; it is also self‐refuting. To avoid this fallacy, one needs to ground arguments with claims that are objective or that hold universally. When the claims on which an argument is based are objectively verifiable or pertain to a set of individuals universally, then the logical necessity of the argument's conclusion may be determined.
