Trade Theory

Famous quotes containing the words trade and/or theory:

“Conversation is a traffick; and if you enter into it, without some stock of knowledge, to ballance the account perpetually betwixt you,—the trade drops at once: and this is the reason ... why travellers have so little [good] conversation with natives,—owing to their [the natives’] suspicion ... that there is nothing to be extracted from the conversation ... worth the trouble of their bad language.”
—Laurence Sterne (1713–1768)

“The struggle for existence holds as much in the intellectual as in the physical world. A theory is a species of thinking, and its right to exist is coextensive with its power of resisting extinction by its rivals.”
—Thomas Henry Huxley (1825–95)
