Sometimes, opening sentences tell you exactly what you need to know about what’s to follow. That’s certainly true of literature. Consider the beginning of Fyodor Dostoevsky’s Notes From Underground (translation Richard Pevear and Larissa Volokhonsky): “I am a sick man . . . I am a wicked man. An unattractive man. I think my liver hurts.” Genius, really. And this notion is definitely true of opinions. Take, as an example, Wal-mart Stores v. Dukes: “We are presented with one of the most expansive class actions ever.” Justice Scalia, from the get go, made clear that the class was doomed. I imagine that readers have other humdingers of beginnings, do tell.
