Attention is a central aspect of the mind. Like for other aspects of the mind, philosophers disagree on how to precisely characterize that aspect. Very generally speaking, attention concerns the current selective direction of the mind. Philosophy studies, for example: (a) The nature of attention. What exactly is attention? How are the various theories of attention in psychology and the neurosciences related to metaphysical nature of attention? (b) The explanatory role of attention. What is metaphysical or explanatory relationship between attention and other philosophically interesting aspects of our lives, such as consciousness, demonstrative reference, salience, agency and intentional action, mindfulness, or emotion, (c) The epistemological, aesthetic, ethical and political role of attention. What is the role of attention in the acquisition and exchange of knowledge, for rationality, or epistemic justification? Are certain forms of attention important for aesthetic appreciation? Does ethical virtue require a certain distribution of attention? Is there something problematic about the contemporary ‘attention economy’?
