The Ethics Incompleteness Principle argues that no rule works in all circumstances, so you have to be alert to when making exceptions is appropriate. The concept is illustrated by how the Boston Red Sox retire uniform numbers.

I will explain…

Major League Baseball teams retire the uniform numbers of players who they want to honor in perpetuity. The number is displayed somewhere in the ballpark, and no player on that team can ever wear it again.

Doing this requires standards, however, or else the honor becomes diluted and the retired numbers include those that seem increasingly strange and arbitrary as time goes by. The New York Yankees have retired so many uniform numbers that no single digit will ever again grace the back of a Yankee star. Moreover, several of the individuals who sanctified those numbers include players who never were and never will be called “great,” like Bernie Williams, who led the league in exactly one category, once, in his entire career, and whose Similarity Score index contains all very good but not great outfielders, the most similar being Paul O’Neil, a former Yankee star whose uniform is not retired. Another retired Yankee uniform number is that of Roger Maris, who only played for the Yankees for six years, many of them unremarkable. Having one’s uniform retired in the Bronx along with those of Babe, Lou, Mickey and Joe appears to mean “Somebody in charge really liked him.”

Well, at least that’s a standard that is easy to maintain.

The Boston Red Sox, in contrast, were not going to have a retired uniform glut. The franchise established an iron set of criteria for the honor, with three prongs:

1. The player must be an inarguable Red Sox great who played at least 10 years with the team.

2. The player must be an elected member of the Baseball Hall of Fame in Cooperstown.

3. The player must retire as a member of the Red Sox.

Today the Red Sox are retiring the number of David Ortiz, who retired himself at the end of last season. While he might well be voted into the Hall of Fame, he may not, for complex and controversial reasons. The Red Sox, who could reasonably argue that Ortiz has been the most popular and important player in the team’s history (though Ted Williams was the best) rightly concluded that to delegate to the  Hall of Fame voters the determination of whether Ortiz’s #34 would be retired with lesser Boston heroes made no sense. Thus his uniform number will momentarily obliterate that second prong, which had already been waived once. In that case, the beneficiary was Johnny Pesky, a classic anomaly and line-blurrer.
