"Identification and definition of the values with which the Constitution is concerned will often fall short of indicating with anything resembling clarity the deference to be given those values when they conflict with others society finds important. (Though even here the process is sometimes more helpful than the commentators would allow.) Nor is it often likely to generate, fullblown, the “neutral” principle that will avoid embarrassment in future cases. But though the identification of a constitutional connection is only the beginning of analysis, it is a necessary beginning. The point that often gets lost in the commentary, and obviously got lost in Roe, is that before the Court can get to the “balancing” stage, before it can worry about the next case and the case after that (or even about its institutional position) it is under an obligation to trace its premises to the charter from which it derives its authority. A neutral and durable principle may be a thing of beauty and a joy forever. But if it lacks connection with any value the Constitution marks as special. it is not a constitutional principle and the Court has no business imposing it. I hope that will seem obvious to the point of banality. Yet those of us to whom it does seem obvious have seldom troubled to say so. And because we have not, we must share in the blame for this decision."
