The head female of a paper-wasp nest allows others to occupy space in her home—so long as they help raise her offspring. The labor market is, however, elastic: if other nests nearby have childcare needs, she maintains a lower work requirement from her “helper” wasps.

James Boswell recorded that during the sale of Henry Thrale’s brewery, Samuel Johnson—an executor of the business—“appeared bustling about, with an inkhorn and pen in his buttonhole, like an exciseman,” and was asked what he considered to be the true value of the property. “We are not here to sell a parcel of boilers and vats,” Johnson responded, “but the potentiality of growing rich beyond the dreams of avarice.”

Including trademarks in books became crucial after the invention of the printing press; without stringent copyright laws, rival publishers could repurpose superiorly edited texts with impunity. Aldus Manutius of Venice, who employed Erasmus as a proofreader, called attention to his company’s “sign of the dolphin wound round the anchor.” Florentine printers were aping the mark, but in the frauds, “the head of the dolphin is turned to the left, whereas that of ours is well known to be turned to the right.”
