"Cantillon has been a much neglected figure in economics. He is known primarily for his influence on Quesnay and the Physiocrats, and for developing the notion that money flows connect the different sectors of the economy. Yet the place of Cantillon in history is more important than this. His Essay can legitimately be regarded as the first real economic treatise. It envisioned the economy as an interrelated system, and explained how that system worked. For this reason, Cantillon probably deserves to be regarded as the first real economist."
