 Intentionality is commonly divided into three constitutive features. First, intentionality has content. The content of an intentional attitude is whatever the attitude in question is about (e.g., the content of the intention to visit the Taj Mahal is to visit the Taj Mahal). Second, intentionality has a mode. The mode is what distinguishes a case of fear from a case of intention, or a belief from a desire. Basic modes are the modes of conative or practical intentional attitudes (such as intentions or desires), cognitive or theoretical intentional attitudes (such as beliefs or perceptions), and affective or emotional attitudes (such as hopes and fears). And third, intentionality has a subject, that is, an entity whose intentionality it is, and to whom it can be ascribed as its source or bearer.
