While you're thinking about that, allow me to give a plug for integrity. Now, I know that everyone is already familiar with the term. And if the concepts do come up in conversation, chances are we've given them negative connotations. Integrity means being a wet blanket. Principles are irrelevant.
Ethics just get in the way.
But I believe that whatever we're planning to do once we leave this campus, we can't afford not to be moralists. It's simply a conscientious approach to life. It involves careful consideration of what you will and will not do. Integrity means figuring out where you draw the line - then drawing it. It's an intensely personal decision, but we need to start thinking about that now , before the barrage of ethical questions hits us.
