I tell my students lots of things. There is the teaching, of course, but there are certain phrases that have become, well, worn. I repeated a story with my ninth graders just a couple of weeks ago. I think that’s a sign.

One of my sayings, usually delivered in class, when a student has interrupted everyone else to declare something like, “There are clouds in the sky,” or “I have a cat”—something that has floated in over the transom of their mind—is this:

“If you have lost the center of the universe, I think I have found it.”

Except, I haven’t told you, there is a secret, and the secret: you are the center of the universe.

Science backs that up—in an infinite universe, everywhere is the center. It’s one of those paradoxes that makes teaching science so much fun. Or like this one from math: which is longer, a ray, which starts at a fixed point and goes on for infinity, or a line, which is infinite in both directions? Something cannot be half as infinite.

That’s why I stick to teaching English.

Take Shakespeare’s universe. In his plays, there is almost—and I’m going to say almost, because unlike math, in English there are always exceptions—almost never anyone more important than the King. The King is always the center of the secular universe.

And you might think, “I’m the king? Cool! I’m the center! I have arrived!” I also tell my students how my daughter thinks that being principal is the best because I get to give out detentions. This is the worst part of the job, and not just because I get to sit on detentions. An authority that gleefully metes out punishments, is truly limited vision of authority. Henry wants—no, needs—his band of brothers to thrive, and they do, because he elevates them. He may be the center, but he is also the first peer, the first equal.

And here’s the trick, In Shakespeare there are only a few truly happy and successful kings. I think he leaves high school principals out altogether. He doesn’t leave students out. And that’s because students can learn. Kings, for the most part, do not. They are, as Caesar claims, as constant than the Northern Star. Once the have become the king they are who they will be. They will not change. And who would wish for an inconstant king? Shakespeare’s tragedies are littered with them: Macbeth, Richard III, even Henry’s father, who mutters, “Uneasy rests the head that wears a crown.” Be a king, indeed.

But, what does it mean to be a center? My juniors and seniors have seen the list of king-becoming graces that Malcolm provides to Macduff: justice, verity, temperance, stableness, bounty, perseverance, mercy, lowliness, devotion, patience, courage, fortitude. It’s quite a list, and like any list we would quibble over each term a bit too much. My students can quibble.

Perhaps it is better to remember that in an infinite universe, if you are the center, so is the person sitting next to you, and so is some person sitting on the other side of the world. We are all centers, and must learn to live and live well with each other. And what better way to live than to live as brothers. Because if we are as brothers, then we shall share a cause—perhaps not so clear as that as faced by Henry at Agincourt, but a cause nonetheless.

And because today is father’s day, again, I am reminded by this:

This story shall the good man teach his son;

And Crispin Crispian shall ne’er go by,

From this day to the ending of the world,

But we in it shall be rememberèd—

We few, we happy few, we band of brothers

And so, today, find your cause, but be sure to make it large enough so that you can be brothers with each other, and with all the other centers that are spinning around you.

And now, I have some diplomas to bestow…
