Printer's ink has been running a race against gunpowder these many, many years. Ink is handicapped, in a way, because you can blow up a man with gunpowder in half a second, while it may take twenty years to blow him up with a book. But the gunpowder destroys itself along with its victim, while a book can keep on exploding for centuries.
A doctor is advertised by the bodies he cures. My business is advertised by the minds I stimulate. And let me tell you that the book business is different from other trades. People don't know they want books. I can see just by looking at you that your mind is ill for lack of books but you are blissfully unaware of it!
There is no mistaking a real book when one meets it. It is like falling in love, and like that colossal adventure it is an experience of great social import. Even as the tranced swain, the booklover yearns to tell others of his bliss. He writes letters about it, adds it to the postscript of all manner of communications, intrudes it into telephone messages, and insists on his friends writing down the title of the find. Like the simple-hearted betrothed, once certain of his conquest, “I want you to love her, too!” It is a jealous passion also. He feels a little indignant if he finds that any one else has discovered the book, too.
