QotD2: "When things are investigated, then true knowledge is achieved; when true knowledge is achieved, then the will becomes sincere; when the will is sincere, then the heart is set right (or then the mind sees right); when the heart is set right, then the personal life is cultivated; when the personal life is cultivated, then the family life is regulated; when the family life is regulated, then the national life is orderly; and when the national life is orderly, then there is peace in this world." - Confucius
