     Piaget² has conducted many careful studies on the evolu-
     tion of games during childhood, and has suggested that moral
     behavior consists in a system of rules, and the essence of all
     morality is to be sought for in the respect which the individual
     acquires for these rules."³Piaget thus equates morality, or
     ethical feeling and conduct, with the individual's attitude
     toward and practice of various rules. This perspective provides
     a rational basis for the analysis of moral schemes as games,
     and of moral behavior as the players' actual conduct.
