There have been printers who were interested in other worlds. The Dutch printer Blaeu studied astronomy under Tycho Brahe, and himself produced in 1600 a celestial globe. The Scottish type-founder Alexander Wilson, although educated as a doctor, became interested in type and left a considerable foundry to his sons before he himself moved on to become professor of astronomy at the University of Glasgow.
If you wish to make the most of this method, you must do it yourself. Then it is you who will have the fun, and then what you learn will stick. What follows illustrates the method briefly by looking at a number of printers in the past five hundred years from one angle, judging them not simply as printers but as men of the world.
It would be nice if we could start with a definition of "man of the world" and a definition of "printer" but actually this small investigation is an attempt at definition. We cannot mean "man of the world" in the Chesterfieldian sense, although there have been many printers who knew how to dress and carry themselves in court and salon, notably Aldus, Caxton and members of the Didot family. Chesterfield would be obliged to allow some of our printers in his company, but I doubt if we could allow him in ours, for in one of his letters to his son he says, "Due attention to the inside of books and due contempt for the outside is the proper relation between a man of sense and his books." Perhaps he was thinking of the vanity of fancy bindings, though it is more likely that he was beguiling himself into one of those untruths common to aphorizers. However that may be, our man of the world does not mean gentleman of the world as Chesterfield thought of gentleman, although there are printers who are both--not all dead.
If we were to speak of the printer as a citizen of the world, we would be coming a little closer to it, but citizen implies being at home in the geographical world, whereas we are thinking of him being at home in the world of ideas. When we say "of" the world, we mean that he knows that he belongs to his contemporary world, that the people and events are of interest to him, the politics, art, science and poetry--not only some particular dexterity, professional specialization or money-making device of his own.
