      They burned the old gun that used to stand in the dark corner up in the garret, close to the stuffed fox that always grinned so fiercely. Perhaps the reason why he seemed in such a ghastly rage was that he did not come by his death fairly. Otherwise his pelt would not have been so perfect. And why else was he put away up there out of sight?—and so magnificent a brush as he had too.

Usage notes

Some authorities proscribe the comparative and superlative forms "more perfect" and "most perfect", on the grounds that perfection is an absolute state.[1][2][3] Nevertheless, graded forms have been in common use in writing for centuries – for instance the Preamble to the United States Constitution, drafted in 1787, describes its goal as "a more perfect Union". In these cases, "more perfect" can mean "closer to perfection", "less imperfect" or "improving upon an already perfect state".
