In order to live in a wider world

From Jacques Barzun's Begin Here: The Forgotten Conditions of Teaching and Learning

But why, after all, learn to read differently by tackling the classics? The answer is simple: in order to live in a wider world. Wider than what? Wider than the one that comes through the routine of our material lives and through the paper and the factual magazines - Psychology Today, House and Garden, Sports Illustrated; wider also than friends' and neighbors' plans and gossip; wider especially than one's business or profession. For nothing is more narrowing than one's own shop, and it grows ever more so as one bends the mind and energies to succeed. This is particularly true today, when each profession has become a cluster of specialties continually subdividing. A lawyer is not a jurist, he is a tax lawyer, or a dab at trusts and estates. The work itself is a struggle with a mass of jargon, conventions, and numbers that have no meaning outside the specialty. The whole modern world moves among systems and abstractions superimposed on reality, a vast make-believe, though its results are real enough in one's life if one does not know and follow these ever-shifting rules of the game.
