Culture is a pillow-word; it shapes itself according to the head resting upon it. In 1968, a group of experts convened by UNESCO defined it as the means by which all goals are articulated, or as the sum of the means created by man to ensure his existence or communicate with his fellows. Another meeting in 1970 took up this definition again, and posited culture as the sum total of knowledge and modes of thought and action which allow man to order his own behavior, his relationships with other men and nature.
