The orange and the ruler

An invented table, one orange, and several incompatible meanings of equal.

Imagine three people at a table with one orange. This is a thought experiment, not a report of an actual quarrel. They have agreed to share it equally. Then someone brings a ruler.

The ruler is a promising beginning. It is also an answer to a question nobody has quite finished asking.

Suppose the orange is cut into three pieces of equal weight. One person says that will do. Another points out that a share of peel is not a share of flesh. The third would prefer to keep the fruit intact until everyone has arrived at an agreement. For the moment, the only thing divided equally is the wait.

We can improve the procedure. Peel the orange first, then weigh the edible portions. But now imagine that one of the three has already eaten an orange and the other two have not. Does that matter? It need not matter to the agreement they made. It might matter to the reason they made it.

Change the scene again. One person brought the orange; another brought a knife; the third washed the plates. Are contributions relevant? If so, how do we compare them without merely giving the largest number to the thing easiest to count?

I am not trying to hide a perfect allocation behind the final paragraph. The orange is too small to carry a universal theory of justice, and these invented people have supplied too little information for one. What interests me is how quickly a precise measurement can make an unfinished agreement look finished.

“Equal weight” is a clear instruction. “A fair share” is a claim about what that instruction achieves. The first does not establish the second by becoming more accurate. An extra decimal place cannot decide whether prior meals or contributions belong in the calculation.

Nor does this mean that every snack requires a seminar. The three might sensibly choose equal portions because the rule is quick, comprehensible and acceptable to them. A modest rule can be good enough without pretending to answer every objection anyone could invent.

There is a version of the scene I particularly like. Before cutting, one person asks, “What did we mean by equally?” Another says, “I thought we meant enough for each of us to taste it.”

That is not the same agreement. It may be the agreement they wanted.

The ruler is still on the table. Nobody needs to throw it away.
