Few punctuation marks elicit quite as much love or hate as the exclamation mark. Its bubbly and exuberant, an emotional amplifier whose flamboyantly dramatic gesture lets the reader know: here be feelings! Scott Fitzgerald famously stated exclamation marks are like laughing at your own joke; Terry Pratchett had a character say that multiple !!! are a sure sign of a diseased mind. So whats the deal with ! ? An Admirable Point recuperates the exclamation mark from its much maligned place at the bottom of the punctuation hierarchy. It explores how ! came about in the first place some six hundred years ago, and uncovers the many ways in which ! has left its mark on art, literature, (pop) culture, and just about any sphere of human activity - from Beowulf to spam emails, ee cummings to neuroscience.Whether you think its over-used, or enthusiastically sprinkle your writing with it, ! is inescapable.
