My high school English teacher, Helen Foley, who helped me become who I am (at least the salutary dimensions), warned me against writing in clichés. These are the antitheses of thinking, she said, and she was so right. In all the years since, when I’m writing and a cliché floats to mind as an effective shortcut to convey what I am thinking, Helen Foley’s words exhort me to actually think and figure out how to write it in my own words. And now I add to that Hannah Arendt’s observation that Eichmann failed to think what he was doing and invoked cliché instead. Peter Levine expands on the peril here.
