After Emerson has discussed how nature, books, and action educate the scholar, he now addresses the scholar's obligations to society. First, he considers these obligations in general, abstract terms; then he relates them to the particular situation of the American scholar.
The scholar's first and most important duty is to develop unflinching self-trust and a mind that will be a repository of wisdom for other people. This is a difficult task, Emerson says, because the scholar must endure poverty, hardship, tedium, solitude, and other privations while following the path of knowledge. Self-sacrifice is often called for, as demonstrated in Emerson's examples of two astronomers who spent many hours in tedious and solitary observation of space in order to make discoveries that benefited mankind. Many readers will wonder just how satisfying the reward really is when Emerson acknowledges that the scholar "is to find consolation in exercising the highest functions of human nature."
The true scholar is dedicated to preserving the wisdom of the past and is obligated to communicating the noblest thoughts and feelings to the public. This last duty means that the scholar — "who raises himself from private considerations, and breathes and lives on public illustrious thoughts" — must always remain independent in thinking and judgment, regardless of popular opinion, fad, notoriety, or expediency. Because the scholar discovers universal ideas, those held by the universal human mind, he can communicate with people of all classes and ages: "He is the world's eye. He is the world's heart."
