The latest installment in the Martin Center’s “History of Higher Ed” series highlights Ralph Waldo Emerson’s 1837 Harvard lecture, “The American Scholar.”

In this distribution of functions the scholar is the delegated intellect. In the right state he is Man Thinking. In the degenerate state, when the victim of society, he tends to become a mere thinker, or, still worse, the parrot of other men’s thinking.

The first in time and the first in importance of the influences upon the mind is that of nature.

Yet when this spiritual light shall have revealed the law of more earthly natures, he shall look forward to an ever-expanding knowledge as to a becoming creator. He shall see that nature is the opposite of the soul, answering to it part for part. One is seal and one is print. Its beauty is the beauty of his own mind. Its laws are the laws of his own mind. Nature then becomes to him the measure of his attainments. So much of nature as he is ignorant of, so much of his own mind does he not yet possess. And, in fine, the ancient precept, “Know thyself,” and the modern precept, “Study nature,” become at last one maxim.

The next great influence into the spirit of the scholar is the mind of the Past—in whatever form, whether of literature, of art, of institutions, that mind is inscribed. Books are the best type of the influence of the past, and perhaps we shall get at the truth—by considering their value alone.

The theory of books is noble. The scholar of the first age received into him the world around; brooded thereon; gave it the new arrangement of his own mind, and uttered it again. It came into him life; it went out from him truth.
