Several smart people started talking about sandwiches on Twitter last week and things quickly got complicated. They got so complicated, in fact, that from “is a taco a sandwich” came mention of “Wittgensteinian ‘family-resemblance.’ ”
There’s no need for scientists’ fancy $25 words here. Sandwiches are pretty simple: a sandwich requires a top and bottom (almost always of the same material), and a middle. All three components must be separate prior to assembly. Two pieces of bread and some vegetables/cheese/meat is a sandwich; a taco, with the shell serving as both “top” and “bottom” (though really as left and right), is not a sandwich.
Feel free to discuss.
