A successful individual typically sets his next goal somewhat but not too much above his last achievement. In this way he steadily raises his level of aspiration.
Kurt Lewin
Liberal education is the pursuit of human excellence, not the pursuit of excellent salaries and excellent forms of polish and sophistication. Liberal education is not even about excellent intellectual achievements. Its goal is more ethical than intellectual: It focuses on the development of individuals as moral agents, and it teaches students how to reflect both analytically and evaluatively on the fact that the choices we make turn us into the persons we become.
