Before anyone invented the paragraph nobody stopped writing because there was nothing to stop writing into the earliest Greek and Latin books ran together as one endless unbroken river of letters with not even spaces between the words which scholars call scriptio continua and it looked exactly like a single sentence that refused to die then around the third century BC a librarian in Alexandria named Aristophanes of Byzantium got tired of people reading his texts out loud with the wrong pauses and started putting little dots in to mark where the breath should go and that was the first paragraph because he realized a thought ends and another begins and the reader needs permission to stop after that the paragraphos arrived as a small horizontal stroke in the margin to flag the start of a new passage then came the pilcrow the little ¶ that meant literally "I wrote this" and it sat politely at the head of each new chunk of sense like a bouncer holding the door open and when Gutenberg and the printers showed up in the fifteenth century they could no longer afford the luxury of one giant scream of text because type is expensive and lines are short and so they made everyone indent and the paragraph hardened into law and that is the whole miserable story of the paragraph a handful of dots that learned to take a breath which is more than you have done since you started typing
