| Abstract: | Three dimensions of propositions, the factual, the epistemic and the modal, and their relationships, are described. The five factor model of personality is based on correlations between ordinary language items. The terms of this language are fuzzy and context-dependent in meaning, and, therefore, unsuitable for epistemic/modal analysis. Hence, one cannot decide to what extent FFM is a priori versus empirical. Only a scientific language, with explicitly stated primitives, axioms, and definitions will permit such a decision. |
