The mind is the totality of psychological phenomena and capacities, encompassing consciousness, thought, perception, sensation, feeling, mood, motivation, behavior, memory, and learning.[1] The term is sometimes used in a more narrow sense to refer only to higher or more abstract cognitive functions associated with reasoning and awareness.[2] Minds were traditionally conceived as immaterial substances or independent entities and contrasted with matter and body. In the contemporary discourse, they are more commonly seen as features of other entities and are often understood as capacities of material brains.[3] The precise definition of mind is disputed and while it is generally accepted that some non-human animals also have mind, there is no agreement on where exactly the boundary lies.[4] Despite these disputes, there is wide agreement that mind plays a central role in most aspects of human life as the seat of consciousness, emotions, thoughts, and sense of personal identity.[5] Various fields of inquiry study the mind; the main ones include psychology, cognitive science, neuroscience, and philosophy.[6]
