"Teachers". . . treat students neither coercively nor instrumentally but as joint seekers of truth and of mutual actualization. They help students define moral values not by imposing their own moralities on them but by positing situations that pose hard moral choices and then encouraging conflict and debate. They seek to help students rise to higher stages of moral reasoning and hence to higher levels of principled judgment.
What is an intellectual? In general, someone seriously devoted to what used to be called the “life of the mind”: thinking pursued not instrumentally, for the sake of practical goals, but simply for the sake of knowing and understanding.
If you're a psychologist, you can instrumentally change peoples' lives for the better.
Iran uses terrorism very instrumentally as an element of foreign policy; they are not just intent on just killing as many people as possible, like al Qaeda. There's no reason to believe that would change.
Our principles fix what our life stands for, our aims create the light our life is bathed in, and our rationality, both individual and coordinate, defines and symbolizes the distance we have come from mere animality. It is by these means that our lives come to more than what they instrumentally yield. And by meaning more, our lives yield more.
