It may help to remind ourselves from time to time that grammar can help to make us not only better writers, but more discerning readers as well. When it comes time, for example, to read outside our contemporary world, putting ourselves in another time and place to see the world from another angle, we can unexpectedly encounter sentence constructions that strike us as strange, if not downright incomprehensible. If the author’s thought is important enough, though, we are compelled to try to understand the meaning, not guessing at it, but analyzing its grammatical form.
One such important author from another time in both American English and American literature is Ralph Waldo Emerson, the renowned transcendentalist who left us a legacy of outstanding thought regally expressed. Emerson lived across most of the nineteenth century (1803-1882), and his literary diction can at times be described as a poetic prose, a flourishing style meant often to evoke its meaning as much as state it outright. One of Emerson’s important essays is entitled “Intellect,” and midway through that piece, he wishes to make clear how what he calls the “constructive,” or artistic, intellect works. He has already told us in the essay that because all of us “have some access to primary truth, so all have some art or power of communication in their head, but only in the artist does it descend into the hand.” And then a few lines later appears this curious sentence: “The conditions essential to a constructive mind do not appear to be so often combined but that a good sentence or verse remains fresh and memorable for a long time.”
But that? What does that sentence mean, and how does that phrase help to construct, as Emerson might say, its meaning? Before we examine the grammar, let’s establish the idiom with another instance. More than one traditional grammar, for example, in discussing this same phrase quotes the English Romantic poet Shelley (early nineteenth century) as writing, “There is no doubt but that they are murderers.” Perhaps we can see the meaning here more readily (It is certain that they are murderers), but what is common to the construction of both Emerson’s and Shelley’s sentences might escape us at first: the independent clause of each is made up of some negative statement. Emerson’s “do not appear” and Shelley’s “there is no doubt” each in its way asserts a negative meaning; Emerson does so by directly negating the verb appear, and Shelley by affirming the noun doubt, whose logic is inherently negative.
Following these initial independent clauses, the phrase but that serves, then, to reverse the preceding negative meaning, so that each sentence is actually affirming something. We will first recognize the word but as a coordinating conjunction that marks opposition or contrariness of some kind between independent clauses (I looked for my watch, but I didn’t find it), but this same conjunction, when combined with the word that, creates a now outmoded two-word phrase which acts as a subordinating conjunction expressing positive exception or singularity. Emerson’s “but that a good sentence or verse remains fresh” means a good sentence or verse will remain fresh, just as Shelley’s “but that they are murderers” means that they certainly are.
So why did not Emerson and Shelley and so many other authors of an earlier time simply say positively what they wanted to say? Because meaning is sometimes made more stirring by not affirming that something is not the case—which means that it is, in fact, the case. The negative sense of the independent clause, in other words, undoes the negative inherent in the conjunction but; and the negative of a negative, rhetorically at least, is most often a positive. The essayist Emerson and the poet Shelley were artistic minds of high rhetoric, certainly, and sometimes the brilliance of insight must be safeguarded by a difficulty of access.
