Education
Just as is illustrated in the quotation, education has the power to foster the stability of society by guiding citizens to abide by the basic rules, while at the same time, citizens can also build up their own happy society by making full use of their knowledge which they receive from the education.
First, education makes people easy to lead and govern. Our social civilization organizes from every member's contribution. Regarding education, what matters most and benefits most would be the awareness that everything has some principles in it, and they can easily understand that our society also needs rules, principles and regulations to work properly. Such an understanding would make the citizens follow the rules of the society, creating a society that can be led and governed with ease. Not only can the science guide us to construct our civilized system wiser, but also the moral encourage us to devote ourselves for a harmonious society, such as trust, compromise and so on. Moral education is an important part in education, which conveys universal doctrines of exhorting citizens to do good and avoid doing bad. The result is, educated citizens consciously accept the regulations by government and show respect for the authorities.
