Writing
In addition to teaching, you could say that research and writing is "what I do." And what I like to do with my writing is to clarify ideas and make them intelligible to other people. Sometimes, as in philosophy, I do this for specialists. I know what I do in philosophy is for specialists because when I gave my mom a copy of my dissertation proposal to read - which I thought was written in plain enough English - she confessed that she found it baffling. So, there you go. You can't enlighten them all, or at least not at the highest level and not all at once.
But what I also like to is to clarify ideas for non-specialists. I've done this in several different subjects, most successfully in some textbooks I wrote for the Republic of Fiji after my Peace Corps service there (1992-2). These are still being used by thousands of students every day.
I have some other things I'm working on now in the philosophy and religion. My ambition is to help make bits and pieces of philosophy more intelligible to non-specialists. The beliefs that we examine in philosophy are fundamental to everything else we do. You might say that they are so fundamental that most of us don't even know that they're there. We go on with our lives, taking these beliefs for granted, but there is tremendous power and tremendous insight to be gained by examining them. It's like what Socrates said about the examined life. Or, at least, that's how I feel about it. The trick, of course, is to make the presentation compelling enough for other people to begin to feel the same way.
An idea is like a waterdrop in a pond: it leaves no other part of the pond untouched.
