Consider what you have in the smallest chosen library. A company of the wisest and wittiest men that could be picked out of all civil countries, in a thousand years, have set in best order the results of their learning and wisdom. The men themselves were hidden and inaccessible, solitary, impatient of interruption, fenced by etiquette; but the thought that they did not uncover to their bosom friend is here written out in transparent words to us, the strangers of another age. We owe to books those general benefits which come from high intellectual action. Thus, I think, we often owe to them the perception of immortality. They impart sympathetic activity to the moral power. Go with mean people, and you think life is mean. Then read Plutarch, and the world is a proud place, peopled with men of positive quality, with heroes and demi-gods standing around us, who will not let us sleep. Then they address the imagination: only poetry inspires poetry. They become the organic culture of the time. College education is the reading of certain books which the common sense of all scholars agrees will represent the science already accumulated. In the highest civilization, the book is still the highest delight.
