The seat of consciousness of the human BRAIN. The mind understands, reasons and initiates action and is also the source of emotions. This is a simplistic definition for a concept that has been and continues to be the subject of vigorous debate among theologians, philosophers, biologists, psychologists, psychiatrists and other doctors; these arguments are too complex for inclusion in a dictionary's definition.

MIND: The National Association for Mental Health, a voluntary charitable body that works in the interests of those with MENTAL ILLNESS, advising, educating and campaigning for and supporting them (www.mind.org.uk).
