Men are both unsocial and social; education therefore should develop individuality and sociability. A sound development of individuality is not necessarily incompatible with a reasonable sociability education. Since our world is still a mad world, the enterprise of sociability education intranationally or internationally so far has been proved to be a failure. This paper critically scrutinizes the concepts, the criteria, the problems and strategies of sociability and sociability education. Foggy as the concept of sociableness or sociability education is, it is, even as an educational slogan, too important to neglect in this new era of warring states, politically or economically. As to the criteria for such an education, the reasonable playfulness and favourable seriousness are, inter alia, propounded. Moreover, some positive and negative strategies are recommended to cure our problems in culture and education, such as, more peace and less unjust wars, more reasonable cooperation and less vicious competition...etc.
