The most famous "active" reader of great books I know isPresident Hutchins, of the University of Chicago. He also has the hardest schedule ofbusiness activities of any man I know. He invariably reads with a pencil, and sometimes,when he picks up a book and pencil in the evening, he finds himself, instead of makingintelligent notes, drawing what he calls 'caviar factories' on the margins. When thathappens, he puts the book down. He knows he's too tired to read, and he's just wastingtime.
