Where Left and Right Came From

Every few years someone draws a line across a whiteboard, writes "left" at one end and "right" at the other, and asks a room full of people to stand where they belong. Most people find a spot. Very few find a spot that tells you anything useful about what they would do if a sheriff, a school board or a federal agency stepped outside the law. That gap, between where people say they stand and how they actually behave, is where this module starts.

Pierson's Liberty Political Matrix is his answer to it. Before looking at the matrix, it helps to know how the line it replaces came to be drawn in the first place. The line is younger than the Constitution, and it began as furniture.

A Seating Chart in Versailles

The words come from the French Revolution. When the Estates General met in 1789 and became the National Assembly, the members began sorting themselves in the hall. Those who supported the old order and a strong royal hand sat to the right of the presiding officer. Those who wanted the revolution carried further sat to his left.¹ The sorting hardened during that summer's arguments over how much power the king should keep, including whether he should hold a veto over the Assembly's laws.

Nothing about the arrangement was philosophical. It was a practical way for allies to find each other and count votes. Over the next generation, though, newspapers and politicians used the seating as shorthand, and the shorthand outlived the room. The left came to be called the party of movement, and the right the party of order.¹

From a room to a map

A seating chart works when there is one question on the table. In 1789 the question was, roughly, how far the revolution should go against the crown. Put that question first and a single line from "keep the king" to "remove the king" makes sense.

The trouble began when the line was carried into other countries and other centuries and asked to hold every question at once: taxes, religion, war, speech, trade, policing, schooling, marriage, immigration and the size of government. A single line can only measure one thing. When it is asked to measure ten, it measures none of them well.

The Ends Keep Moving

The meaning of each end has drifted so far that the same word can point in opposite directions depending on the country and the decade.

In much of the nineteenth century a "liberal" was someone who wanted free markets, limited government and individual rights against the crown and the established church. In Europe the word still often means that. In the United States, by the middle of the twentieth century, "liberal" had come to mean someone who favored a larger role for government in economic life. A Victorian liberal and a modern American liberal would agree on very little.

American parties have shifted too. The coalitions that made up the Democratic and Republican parties in 1900, 1950 and 2000 were different coalitions, with different regional bases and different positions on trade, race, war and the reach of federal power. Each time, the left-right line was redrawn to fit, and each time the people standing on it were told they belonged at one end or the other.

That flexibility is why the line survives. It can absorb almost any set of positions. It is also why the line explains so little. A map that can be redrawn to fit any territory is not telling you much about the ground.

Where Pierson Begins

Pierson's public explanation of the matrix opens with the problem in one sentence: "Labels describe affiliation, not behavior." He goes on: "Terms such as conservative, liberal, or moderate do not explain how individuals act when power, law, and moral pressure converge."²

That is a narrower complaint than it may sound at first. Pierson is not saying parties or ideologies do not matter. He is saying a label tells you which team a person joined. It does not tell you whether that person will follow the Constitution when the Constitution is inconvenient, whether they will defend an institution that is being used to crush a neighbor, or whether they will drop a principle the moment it costs them an election.

Those are the questions he cares about, and the left-right line has no place to record the answers. Two officials can both call themselves conservatives. One votes against her own party to keep a promise to her district and pays for it. The other votes with leadership every time, no matter what the bill does, because staying in good standing is the point. On the line they stand side by side. In the matrix they land in different cells.

The question behind the matrix

Pierson builds the matrix on what he calls a fixed premise of ordered liberty: "Liberty is not chaos, and order is not control. Liberty requires structure, but only just structure. Order requires authority, but only legitimate authority." From that premise he draws his test: "The operative question is not identity, but conduct under pressure."²

Readers who took the Ordered Liberty module will recognize the shape of that sentence. The matrix is the same framework turned outward, used to read the conduct of officials, movements and citizens. The next lesson takes up Pierson's stronger claim, that the left-right line is not merely incomplete but a false paradigm that keeps citizens fighting each other while power gathers above them.
