When Arctic traveler Vilhjalmur Stefansson traded with the Inuit of Victoria Island in 1911, he found the metal of their knives to be of curious provenance: Inuit to the east had bought guns from the Hudson Bay Company and traded them westward; the firearms were then traded farther west, eventually reaching the Inuit he’d met—who, having no use for guns, had beat the metal barrels into knife blades.

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.”

Ottoman humorist Yusuf al-Shirbini of Egypt railed against unfair levies, referring to them as “things being called innovation.” Al-Shirbini quoted scripture: one who brings about “an innovation or provides accommodation for an innovator, upon him be the curse of God.”
