As an Irish parliamentarian, Edmund Burke once said that he owed his constituents not just his industry but his judgment, and that if he voted according to their opinions rather than his own judgment he would betray rather than serve them.

This failure to flatter his audience helps explain why he’s better remembered today as a philosopher than as a practitioner of politics. But the distinction he made gives us a key to mending our democracy.

Today, when push comes to shove, politicians’ allegiance is neither to their judgment nor their constituents’ opinion, but to their party. (It is worth noting that political parties were in their infancy in Burke’s time.)
