The aim of this article is to analyze and criticize Roderick Chisholm’s conception of intentionality, which has, historically, served as the point of departure for most accounts of intentionality in analytic philosophy. My goal is to highlight the problematic ‘logico-linguistic commitment’ presupposed by Chisholm, according to which mental concepts should be interpreted by means of semantic concepts. After addressing Chisholm’s differentiation between the ontological thesis (the idea that the intentional object might not exist) and the psychological thesis (the conception that only mental phenomena are intentional), as well as his defining criteria for intentionality (non-existential implication, independency of truth-value, and indirect reference), I focus on the manifold problems presented by his theory. First, the two initial criteria entail a conceptual confusion between the semantic concept of ‘intensionality’ and the mental concept of ‘intentionality’. Second, according to these criteria””and against Chisholm’s explicit intention””perception and other cognitive activities should not be considered intentional. Third, there are no grounds for the artificial conflation of intentionality and the concept of ‘propositional attitudes’””an equation which is an explicit tenet of the logico-linguistic commitment. In general, I argue that an interpretation of intentionality based on this commitment obscures the true meaning of the concept of intentionality, as it is presented, for instance, by phenomenology.
