A single word hangs alone at the top of Jim Leftwich's «Thesis 92», and it sets the terms for everything after it: "duration." A thesis is supposed to be an argument, a claim you can defend. What the poem delivers is one word, a question, and a strange fragment about birds. The number in the title suggests a longer run of pieces, though the text itself doesn't tell us. The mismatch between the confident title and the slippery content is the first joke, and also the first idea: the poem is less a statement about language than a small test of what language can hold.
"Duration" is a good word to start with because it sits between science and philosophy. It names how long something lasts and also how time feels from the inside. It is also oddly empty. It has no object and no picture attached. After it the poem asks, "how can we speak of / eclipse / worship / value / frenzy." The four words arrive one per line, with no commas, so they read as a list, and they come from different worlds. An eclipse is astronomical, worship religious, value economic or moral, frenzy emotional. Yet the missing punctuation lets them couple into odd compounds, "eclipse worship" and "value frenzy," as if the words were slipping into each other. An eclipse also has a duration, a beginning and an end, which quietly links the opening word to the list. The rhythm backs this up. "Eclipse" stresses its second syllable, but "worship," "value" and "frenzy" all fall on the first, so the list starts with a small stumble and then settles into a drumbeat of two-syllable words.
The question never gets a question mark. That omission matters, because without it the sentence doesn't have to end. Read straight through the stanza break, the poem could be a single unfinished thought: how can we speak of eclipse, worship, value, frenzy, the non-spectrum of incomprehensible pigeons? On that reading the pigeons are the final item on the list, the thing the grand abstractions have been heading toward all along.
And what a strange destination it is. "Non-spectrum" sounds technical, like a term coined for a laboratory. A spectrum is an ordered range, light sorted into its colours, and an eclipse is exactly what happens when light is blocked, so the word echoes the earlier image. The "non-" simply cancels it. What is left is a range with no order. Then "incomprehensible" arrives, six syllables stretched across a line break from the small word "of," and the poem lands on "pigeons," two syllables, plain and slightly comic. The p sounds in "eclipse," "spectrum," "incomprehensible" and "pigeons" give the ending a faint popping, cooing texture that feels almost bird-like. The adjective is also ambiguous. Are the pigeons themselves incomprehensible, flocking and muttering in a language we can't read? Or does the word describe our failure to make sense of them? The poem leaves both possibilities open.
The shape on the page does much of the work. There is no rhyme and no regular metre. The poem is lowercase and unpunctuated, and its rhythm comes from white space. The longest line, "how can we speak of," is followed by a vertical column of single words that slows the reader down, each one given a moment to sit alone. Then the final lines widen again into the longer phrase about pigeons. The poem moves from one word, to a question, to a stack of nouns, to an image, so the abstractions end up pressed against something concrete and slightly ridiculous.
That collision is where the poem's significance lies. It doesn't explain why big words like "worship" and "value" resist being spoken about; it shows it. The question is real, but the answer it gets is a cloud of birds nobody can decode. Judging by the text alone, «Thesis 92» treats words as material to be arranged rather than messages to be unpacked. For a student reader, that makes it a useful provocation: a poem that is funny and serious at once, and that asks you to notice how much of what we say rests on words that give way when you lean on them.
