From his 1986 commencement speech to Ohio State University:
"Paying forward — that is the thing that you folks with your great education from here can do for the rest of your lives. I was so happy the other day when I saw in the paper about Jim Lachey, who played here one year ago and comes back after one year of professional football to give a six-figure gift to the University. And what he said was, ‘I received a great education here and I got to play great football under Coach Bruce, and under a great football system here. I want to help some other youngster to do the same thing.’
"Take that attitude toward life, because so seldom can we pay back — those whom you owe — your parents and other people — will be gone. Emerson had something to say about that.
"He said you can pay back only seldom. But you can always pay forward, and you must pay line for line, deed for deed, and cent for cent. He said beware of too much good accumulating in your palm or it will fast corrupt. That was Emerson's attitude and no one put it better than he did.
"I might mention a couple of people. Jim Lachey is one who is already paying forward. Two weeks ago in Michigan, a former football player of ours passed away. He was in his 60s. He had been in the Marine Corps during World War II, on Okinawa — there were only 30 from his outfit that survived. That made a difference in him. He came back to coaching and he was a great coach. His name was Jack Castignola. He sent his son, Greg, here as one of our quarterbacks. Jack Castignota won nine championships — undefeated season, and all that — but he did something bigger: He coached 126 players who went on to college. One hundred and twenty-six players went on to college and that was his way of paying forward.
"We had a great dean of agriculture here by the name of Roy Kottman, who retired a couple years ago. And on his retirement, he and I were having lunch one day in the Faculty Club, and I said, ‘Roy, how did you happen to go to Iowa State?’ ‘Oh,’ he said, ‘I was working back during the Depression for $1.50 a day pumping gas and I couldn't save any money. But an old man in that community in Iowa came to me and said, “Roy, if you'll go to Iowa State, I'll pay your tuition.” So I went to Iowa State and worked for my room and board, graduated, went into the service, came back, got my master's, my doctorate, went to West Virginia as dean of the agriculture college, and then I came to Ohio State.’ He was here 23 years, and in those 23 years, he virtually doubled food production in Ohio. On top of that, he graduated thousands of youngsters. On top of that, he helped to feed hungry mouths all over the world. All because that old man back in Iowa said, ‘Roy, if you'll go to Iowa State, I'll pay your tuition.’ That's paying forward."
