Abstract
Conceptualization and measurement of organizational commitment involve different dimensions that include economic, affective, as well as moral aspects labelled in the literature as: ‘continuance’, ‘affective’ and ‘normative’ commitment. This multidimensional framework emerges from the convergence of different research lines. Using Aristotle’s philosophical framework, that explicitly considers the role of the will in human commitment, it is proposed a rational explanation of the existence of mentioned dimensions in organizational commitment. Such a theoretical proposal may offer a more accurate definition of ‘affective commitment’ that distinguishes feelings from rational judgments. The use of a philosophical explanation coherent with psychological findings also allows the discovery of a wider moral concept of ‘normative commitment’.
