Answer

What a wonderful question the gentleman has asked, and I cannot escape answering him. First I will say that you have hit upon the view of the great ones. When I was a child, we went on a trip with the yeshiva high school to Mea Shearim. When we went in there to pray Mincha, one of the locals asked me my name, and I said to him, “Why do you ask my name, seeing it is wondrous?” But in the end I answered, and when I said Michi (with a hard k), that fellow wondered to himself whether my full name was Mikal.
And later, when gray hair had appeared upon my head, I studied in the books of our analytic philosopher masters (the great Rabbi Rabbi B. Russell and his disciples), and I saw that a person’s name is conventional by agreement (see Two Carts, Gate Two), as opposed to a description (informative and designating). It therefore follows that there is no need whatsoever for consistency between a full name and a nickname, so long as it is clear to whom the words refer. Thus were the claims of that scoundrel, the man in stripes, stopped up. And so my well-being surged like a river, and my mouth was filled with song like the sea, and my lips with praise like the multitude of its waves: “Give thanks to the Lord, for He is good, for His kindness endures forever,” who gives the rooster understanding to distinguish between blue dye and indigo, and between a name and a description.
