 Intentionality  The word ‘intention’ is relatively unambiguous outside of philosophy. But philosophers use the word ‘intention’ and especially the adjective ‘intentional’ to refer to a feature of a class of mental states that includes but is not limited to intentions ordinarily understood. This is the property of being about or directed at objects, including not only real concrete objects, but also abstract and fictional objects, properties, and states of affairs. Thus believing that it is raining, hoping to get a computer for Christmas, talking about Sherlock Holmes, figuring out the square root of six hundred and twenty five, are all intentional states and activities, as is intending to bake a cake. It is often assumed that minds, mental states, have intrinsic intentionality, and that utterances and sentences have only intentionality in a derived sense: they have it from the intentionality of the mental state they express.
