Seeking a Philosophical Basis for Trait Psychology

Abstract

I summarize an early effort to provide a conceptual basis for psychology. Natural science studies material objects, and its methods and assumptions may not be appropriate for the study of persons. Persons exist within the natural attitude and are characterized by such properties as temporality, responsibility, normality, and identity. Contemporary theories of mind focus on people’s understanding of how minds make decisions and shape behavior, but say little about the nature of the entity that possesses a mind; ethnopsychologies are concerned with cultural variations in beliefs about accidental rather than essential aspects of human psychology. The lay philosophical view of the person sketched here is intended to be broader and deeper. It is particularly relevant to trait psychology, appears to have been implicit in much trait research, and is generally consistent with empirical findings on personality traits.
