From James Grant’s review of Frédéric Bastiat’s works, (hat tip David Boaz)
Because nobody else can understand them, modern economists speak to one another. They gossip in algebra and remonstrate in differential calculus. And when the pungently correct mathematical equation doesn't occur to them, they awkwardly fall back on the English language, like a middle-aged American trying to remember his high-school Spanish. The economist Frédéric Bastiat, who lived in the first half of the 19th century, wrote in French, not symbols. But his words—forceful, clear and witty—live to this day.
