Forty years is the unit of work in focus here. You have or will have units of forty years of your own, a unit of work like this. I hope what you are doing for me is also for you and your work and your encourage-ment about the decades behind you or to come. I can best respond to your generosity with a look back at the course of this effort of mine and its internal and external connections over time, to illustrate and help us keep in mind the way we mutually influence each other in our thought and lives. If the effort of one of us rounded into a unit is made an occasion to bring us together and a focus for reflection on where we are in our per-ception and development, it needs its context.
