I’m writing this, my second blog, on the birthday of my oldest son and a day when much of the U.S. is watching presidential primary results. I find myself thinking about words, action and change—three concepts that have been debated relentlessly on the airwaves in this U.S. primary season. How do words link to actions that bring about change?

Let me start with my son who spends his days in abstract thought. He is a mathematician, a logician, whose thoughts and work are understood by only a very small number of people around the world. He teaches more accessible math at a university, but his research time is spent thinking and then writing in words and symbols which only a few understand. When I asked him once how his ideas might be applied a hundred years from now, he smiled his patient smile and asked, “Mom, do I ask you how your literature applies?”

All right, I get that. I understand the value of pure ideas, ideas for their own sake. I understand the need to think and to add to the universe of thought even if one doesn’t know the value the thoughts may have and even if they are shared with only a few. It is a way of ordering, discovering and revealing the harmony of the universe.
