 Intentionality  is the property of being about something, having content. In the 19th Century, psychologist Franz Brentano re-introduced this term from Medieval philosophy and held that intentionality was the “mark of the mental”. Beliefs and desires are intentional states: they have propositional content (one believes that p, one desires that p, where sentences that represent propositions substitute for “p”). Searle’s views regarding intentionality are complex; of relevance here is that he makes a distinction between the original or intrinsic intentionality of genuine mental states, and the derived intentionality of language. A written or spoken sentence only has derivative intentionality insofar as it is interpreted by someone. It appears that on Searle’s view, original intentionality can at least potentially be conscious. Searle then argues that the distinction between original and derived intentionality applies to computers. We can interpret the states of a computer as having content, but the states themselves do not have original intentionality. Many philosophers endorse this intentionality dualism, including Sayre (1986) and even Fodor (2009), despite Fodor’s many differences with Searle.
