A Little History of Economics

Imagine a world without money, where exchanging goods means finding someone who wants exactly what you have and has exactly what you want. This was the reality for early humans and even for ancient civilizations until the invention of money. Scarcity, the condition of having limited resources but unlimited desires, is the heartbeat of economics. It compels us to make choices, to weigh what we gain against what we give up. The ancient Greeks, the first to ponder these questions deeply, saw economics as the art of managing the household. Their insights, though born in small city-states, echo through centuries.

Think of Aristotle, who distinguished between natural wealth, like food grown for use, and unnatural wealth, like money used to make more money. His skepticism about moneylending and profit-making reflected a world where commerce was still taking shape. Yet, he understood the power of money as a tool to ease exchange, a revolutionary idea that would shape economies for millennia.

Money first appeared as electrum coins in Lydia, a simple mixture of gold and silver, stamped to certify value. This innovation solved the inefficiencies of barter, allowing people to specialize in what they did best and trade for what they needed. Money became the invisible thread weaving society together, enabling complex economies to flourish.

But economics is not just about money; it’s about the choices we make because we cannot have everything. When a student chooses history over geography, the real cost is the lost opportunity to learn about deserts and glaciers. This concept, called opportunity cost, is fundamental. Every decision carries a hidden cost, the value of the next best alternative forgone.

As we begin this journey through economic thought, remember that at its core, economics is a human story about how we survive, thrive, and cooperate despite scarcity. From the humble household to the vast market, these ideas form the roots of a discipline that seeks to understand life itself.

Let us now move forward into the medieval world, where economics intertwined deeply with faith and morality, shaping how societies viewed wealth and justice.
