Perhaps I ought to add a caution about words. I said that words were, metaphorically, fields of force. May I, in my metaphorical, poetical, and unscientific way, press this analogy a little further. It is as dangerous for people unaccustomed to handling words and unacquainted with their technique to tinker about with these heavily charged nuclei of emotional power as it would be for me to burst into a laboratory and play about with a powerful electromagnet or other machine highly charged with electrical force. By my clumsy and ignorant handling, I should probably, at the very least, contrive to damage either the machine or myself; at the worst I might blow up the whole place. Similarly, the irresponsible use of highly electric words is very strongly to be deprecated.
–Dorothy L. Sayers, “Creative Mind” (1942)
