The mind is a set of cognitive faculties including consciousness, perception, thinking, judgement, and memory. It is usually defined as the faculty of an entity's thoughts and consciousness. It holds the power of imagination, recognition, and appreciation, and is responsible for processing feelings and emotions, resulting in attitudes and actions.
There is a lengthy tradition in philosophy, religion, psychology, and cognitive science about what constitutes a mind and what is its distinguishing properties.
One open question regarding the nature of the mind is the mind–body problem, which investigates the relation of the mind to the physical brain and nervous system. Pre-scientific viewpoints included dualism and idealism, which considered the mind somehow non-physical. Modern views center around physicalism and functionalism, which hold that the mind is roughly identical with the brain or reducible to physical phenomena such as neuronal activity. Another question concerns which types of beings are capable of having minds. For example, whether mind is exclusive to humans, possessed also by some or all animals, by all living things, whether it is a strictly definable characteristic at all, or whether mind can also be a property of some types of man-made machines.
Whatever its nature, it is generally agreed that mind is that which enables a being to have subjective awareness and intentionality towards their environment, to perceive and respond to stimuli with some kind of agency, and to have consciousness, including thinking and feeling.
