Abstract

This chapter focuses on one of the common fallacies in Western philosophy called 'psychologist's fallacy'. William James, in his Principles of Psychology, coined “the psychologist's fallacy”. It is a fallacy of relativism. James articulated the psychologist's fallacy as if it were a confusion between first‐person and third‐person points of view. Importantly, an experience and its description are different, and from the first‐person point of view, whatever a person experiences is identical with what that experience is. Therefore, the first‐person point of view of an experience, because it is the view of actually having the experience itself, is itself the truth of the experience. To avoid this fallacy, one needs to ground arguments with claims that hold necessarily and universally. Neither descriptions of experience based on subjective judgments nor the occurrence of specific accidental‐psychological events hold necessarily or universally regarding human psychology.
