Six short lines, two stanzas, and a paradox that takes a moment to sink in. "Balance" gives its reader two pieces of advice that seem to pull in opposite directions: be modest, and be confident. Most of us expect to be told to choose one. Gingerich insists on both, and his title explains why. Balance here is not a compromise sitting comfortably in the middle. It is a tension held on purpose, like a person standing on a seesaw without tipping it either way.
The poem's construction makes this tension visible. The two stanzas are built almost identically. Each opens with an imperative verb or pair of verbs ("Be modest and humble"; "Aspire, be confident"), moves to the same phrase, "There's no ... substance / In the world than in you," and closes on the same final line. Only two words change: "cruder" becomes "finer." The repetition works like a mirror, and the reader is invited to hold the two halves up against each other. When so little differs, those two adjectives carry the entire weight of the poem.
The word "substance" is what makes the poem unusual. A less careful writer might have said "creature" or "person" or "soul." Substance is a word from chemistry and philosophy, something material, something you could in principle weigh or analyse. By describing a human being this way, the poem reduces the self to raw stuff: clay, dust, ore. That is where the claim about cruelty comes from. There's no cruder substance than you, because you are made of the same coarse material as everything else, and you know your own flaws from the inside better than anyone. Yet the same word, turned around, delivers the opposite verdict. Substance can be refined, and the finest things we know, metal, glass, or gemstones, are made from the crudest. The poem never says so outright, but the logic of the word hints at it: crude and fine are not two different materials but two states of one material.
That is why the phrase "in you" matters so much. Both statements are addressed directly to the reader, and both locate their evidence inside a single person. The poem does not say "others are crude, you are fine." It says that the full range, from the lowest to the highest, is contained in one self. Humility, then, is not self-hatred, and confidence is not vanity. Each is a truthful reading of something real. To be only modest would be to forget the finer substance; to be only confident would be to forget the cruder one.
Notice, too, how the poem's rhythm supports its message. The lines are short and plain, with no ornament and no elaborate imagery beyond the one central word. The pacing is closer to a proverb or a piece of advice spoken aloud than to a lyrical meditation. There is no rhyme scheme to speak of; the poem relies on repetition rather than sound-matching, and the effect is calm and deliberate. Even the verbs differ in temperature: "modest and humble" is a quiet, settling pair, while "Aspire" lifts the second stanza upward. The movement from stillness to reaching mirrors the content, a small gesture of rising built into the grammar.
What makes the poem worth reading is its refusal of the easy version of either virtue. Plenty of advice tells young people to believe in themselves; plenty more warns them against pride. Gingerich fits both into twenty or so words and trusts the reader to feel the friction between them. The ending is open: the poem does not tell you how to hold the balance, only that you must. Perhaps that is the real lesson. Balance is not a fixed point you arrive at but something you keep doing, one moment of humility, one moment of ambition, again and again, with the same substance underneath.
