Original (1659)
THE Jews were once the only outward, visible people of God, who were chosen by God for a peculiar people, who had the promise of, and expected, the Messiah; whose faith and hope of salvation was in him; yea, and at that very time they were looking for him, yet, when he came, he was "a stone of stumbling, and a rock of offence" to them, and they could by no means receive him. They were full of reasonings, and doubts, and contendings about it; but could never, with all their wisdom from the letter, determine that was he.
— Isaac Penington, The Jew OutwardFriends Illuminated
The Jews were once the only outward, visible people of God — chosen by him to be a special nation. They held the promise of the Messiah and expected his coming. Their entire faith and hope of salvation rested on him. Yet at the very time they were actively looking for him, when he finally came, he was "a stone that causes people to stumble and a rock that makes them fall." They could not receive him by any means. They were full of reasoning, doubts, and objections. Yet for all their knowledge of Scripture, they could never recognize that this was him.

The shading marks sentence boundaries. Penington’s first sentence runs 74 words across three semicolons before it stops; ours runs 31 at its longest. Nothing was cut — the modernized passage is three words longer than the original. Modernization here is not compression. It is the same argument, broken into units a reader can hold.

Sarah Grimké’s Letters, already written for a popular audience in 1838.
Shorter sentences, not a shorter book
Across the 31 editions we can measure end-to-end, the modernized prose is 96% the length of the original — and once introductions and notes are counted, 22 of 31 run longer than the book they came from. You are not buying an abridgement.
What we add, counted
Introductions, chapter summaries and notes are written for each edition and measured separately: a median 9% of the finished book, 163,627 words across the catalogue. Every product page reports its own figure.
Method. Both texts were measured by the same program, with the same definition of a word and a sentence. Semicolons and colons are not treated as sentence endings — that is precisely the feature being measured. The original is the Quaker Heritage Press transcription; the modernized text is the shipped edition, quoted in full. Grade level is Flesch–Kincaid (Kincaid et al., 1975). We do not claim the modernized edition is faster to read. Reading rate is driven mostly by individual word difficulty rather than sentence structure (Kuperman, Buzato & Rothe-Neves, 2025), so a “hours saved” figure would not be honest. What we claim is what the numbers above show: less to untangle per sentence.
