“In many ways, writing is the act of saying ‘I,’ of imposing oneself upon other people, of saying listen to me, see it my way, change your mind. It’s an aggressive, even a hostile act . . . setting words on paper is the tactic of a secret bully” (Joan Didion, “Why I Write,” New York Times Book Review, 12/05/76). Didion’s incisive writing filled me with admiration. Yet her skill at voicing opinions antithetical to mine, most notably in her early pro-conservative years, also aroused my aggravation. Didion’s scathing arguments didn’t win me over, but I resented her for being such a good adversary.
