[From a Speech on Repealing the Salary Clause, 1873.]

One of the brightest and greatest of men I know in this nation [Louis Agassiz], a man who, perhaps, has done as much for its intellectual life as any other, told me not many months ago that he had made it the rule of his life to abandon any intellectual pursuit the moment it became commercially valuable; that others would utilize what he had discovered; that his field of work was above the line of commercial values, and when he brought down the great truths of science from the upper heights to the level of commercial values, a thousand hands would be ready to take them, and make them more valuable in the markets of the world. He entered upon his great career, not for the salary it gave him, for that was meagre compared with the pay of those in the lower walks of life; but he followed the promptings of his great nature, and worked for the love of truth and the instruction of mankind.
