Abstract
This article engages in an exploration and identification of potential internal contradictions such as logical errors in the marginal utility theory of value. Specifi-cally, it explores and attempts to identify possible logical contradictions between certain integral elements and aspects of this theory. It first investigates and ana-lyzes potential logical contradictions between the ‘law of satiable wants' and the ‘law' of diminishing marginal utility within the marginal utility theory of value fo-cusing on its early formulations and later elaborations. It then explores and ana-lyzes possible logical contradictions between the status of marginal utility theory as a subjective or individualistic and as a psychological theory of value. It con-cludes that the marginal utility theory of value manifests certain internal contra-dictions in the form of logical errors.
