Having failed of the thought often I fail of the words. When I have a particularly M.-Mac-Lane thought to express I review the top tier of my vocabulary of words to find proper ones for it. They are all very nice words in that top-tier--neatly washed and dressed and hair-brushed and tidied-up, like the children in a small private school: words like Necessary and Irresolute and Crockery and Inconvenience and Broth and Apprise: good words and useful if one’s thought is radical or risky and wants conserving. I call some of them to me and question them and consider them and ponder a bit, and decide they will none of them suit. Then I go to the bottom tier, the unkemptest of words in the untidiest attire: words like Traipse and Nab and Glim and Hennery and Chape and Plash. And I at once reject those as too carelessly bred for my terse thoughts to associate with. (But for my uncombed ungroomed grimy-faced thoughts I turn to them.) Then I glance over a tier of mysterious words, spruce but with indefinable vagabond faces: such as Whelk and Mauger and Frush and Gnurl and Yare and Hyaline. They are expressive but of a kind it’s well to use with caution, the kind that may trip up thoughts that would make them their medium and lead to slips ’twixt cups and lips. So I dismiss them with a mental reservation of one or two to use if I fail to find right ones among the less mysterious. Then I turn to a tier that represents the virile middle-class in words, the lower-case words, the mob and riot words, the words for poets and anarchists and prophets: such as Adroit and Nightingale and Gallows and Gutter and Woman and Madrigal and Death. And I say, ‘Without doubt here are my words.’ But I use discretion. I know that tier of words to be of the nature of bombs, of strychnine, of a dynamic force resistible against all human and wordly substance. They also must be used cautiously and with a sparing hand. With caution one can handle a bomb, and sparingly one can eat strychnine, and one can control any dynamic force by studying its tendencies and keeping out of its direct road. It behooves one to heed those conditions in broaching the countermining counter-irritant words if one would avoid blowing oneself analytically broadcast.
