Ever since President Obama announced that he would seek out an empathetic replacement for David Souter on the Supreme Court, the nation has engaged in a revealing debate about empathy. No one denies that empathy is an important quality for our daily lives, and something we should engender in our kids. But there is an honest disagreement about whether empathy is an appropriate qualification for a judge.
Liberals like empathy, because compassion brings mercy, and mercy is seen as an important part of good judging. Conservatives denounce empathy, saying compassion breeds judicial activism. Law professor Steven Calabresi has warned that asking judges to be empathetic is like removing the blindfold from the iconic Lady Justice, allowing the judge to decide in favor of whichever perspective elicited more feelings of compassion.
If empathy is simply a matter of being open to feeling a certain amount of sympathy for one party or the other, the conservatives may be right that it creates risks for a judicial institution. Judges might be too quick to base judgments on unacknowledged bias or prejudice.
There is a better definition of empathy for the judicial context, however, that focuses not on how judges feel but how they think. This kind of empathy is not only beneficial for the institution, but crucial. And David Souter has embodied this kind of empathy in his tenure on the court. Let me explain.

and pithy expressions. For these critics, Judge Sotomayor must disappoint, for she writes opinions that are said to "avoid quotable language."
As one of David Souter's most conservative former clerks, I have always winced at the Republican slogan of "no more Souters" for the Supreme Court. Most conservatives feel - rightly, in many respects - that Justice Souter disappointed their hopes to move the court in a dramatically rightward direction. Conversely, liberals take the view - again, with some justification - that Justice Souter has been a bulwark of respect for liberal Warren and Burger Court precedents and a key vote for advancing the liberal agenda in areas like gay rights and the death penalty. But this conventional wisdom misses the important sense in which Justice Souter remained a methodological conservative throughout his career. That conservative approach to the judicial task ought to inform both assessments of Justice Souter's legacy and the debate over the nomination of his successor.
