“If I have done anything for the colored people, it is in a great measure due to my having had the good-fortune, when I escaped from slavery, to become acquainted with William Lloyd Garrison, and with Wendell Phillips, and with our friend Oliver Johnson, and with Dr. Bowditch. The home of Dr. Bowditch, I may say, gave me the first shelter I received in this city. I have often been asked where I got my education. I have answered, from the Massachusetts Abolition University, Mr. Garrison, president… I meet with colored men on all sides smoking and sometimes drinking. That is not the way to rise in the world. For my own part, I neither smoke, nor chew tobacco nor take snuff, nor drink whiskey; and I should be delighted if I could make the same statement with regard to my whole people.”

Sometimes said to have been the first usage of this now ubiquitous cliché, though in fact the phrase university of life had been in use for many years. Some early instances:
"The disciplined minds that go from [their university's] walls will be its jewels…It will worthily introduce them to the University of Life." ~ The New Englander and Yale Review (February 1853), p. 70.
"The late Professor Greenleaf…who, not born to affluence, and not bred up to scholarly studies, achieved an honorable scholarship in the university of life". ~ Cornelius Conway Felton An Address Delivered before the Association of the Alumni of Harvard College, July 20, 1854 (Cambridge, Mass., 1854), p. 7.
"But God be thanked…for the university of life where we may acquire, at the same time that we put in practice, the rules which are to fit us for, and conduct us through the eternities." Elizabeth D. Livermore Zoë (Cincinnati, 1855), p. 14.
"When our men go into the great university of life…there are few, indeed, who have practical reason to regret that so many years were spent in the severe but salutary discipline imposed by the University of Dublin." ~ The Dublin University Magazine (April 1858), p. 419.
