Climax (gradatio) consists of arranging words, clauses, or sentences in the order of increasing importance, weight, or emphasis. Parallelism usually forms a part of the arrangement, because it offers a sense of continuity, order, and movement-up the ladder of importance. But if you wish to vary the amount of discussion on each point, parallelism is not essential.
- The concerto was applauded at the house of Baron von Schnooty, it was praised highly at court, it was voted best concerto of the year by the Academy, it was considered by Mozart the highlight of his career, and it has become known today as the best concerto in the world.
- At 6:20 a.m. the ground began to heave. Windows rattled; then they broke. Objects started falling from shelves. Water heaters fell from their pedestals, tearing out plumbing. Outside, the road began to break up. Water mains and gas lines were wrenched apart, causing flooding and the danger of explosion. Office buildings began cracking; soon twenty, thirty, forty stories of concrete were diving at the helpless pedestrians panicking below.
- To have faults is not good, but faults are human. Worse is to have them and not see them. Yet beyond that is to have faults, to see them, and to do nothing about them. But even that seems mild compared to him who knows his faults, and who parades them about and encourages them as though they were virtues.
In addition to arranging sentences or groups of short ideas in climactic order, you generally should also arrange the large sections of ideas in your papers, the points in your arugments, and the examples for your generalizations climactically; although in these cases, the first item should not be the very least important (because its weakness might alienate the reader). Always begin with a point or proof substantial enough to generate interest, and then continue with ideas of increasing importance. That way your argument gets stronger as it moves along, and every point hits harder than the previous one.
