“Only connect,” writes James Dickey in a poem about a powerline worker. I make a few small connections from time to time, and they always give me pleasure. Not much to do with them otherwise but report them, so here goes.
Here’s one: We have all frequently heard the phrase “common sense,” usually together with the popular remark, on the verge of cliche itself, that it isn’t really common at all. I suspect there is a confusion here between two senses of the word “common.” In the modern sense, we mean “to be found anywhere.” I suspect the phrase originally meant “common” in quite another way. The older meaning is “basic, fundamental.” In other words, if you had even the elements of the most basic rules of making sense, you had common sense. The implication is that it does not require a genius of logic or philosophy to tell what is what, but that even “common” or basic sense will suffice.
