エッセイおよび書簡集 "The Man From Main Street " （「『本町通り』から来た男」の意）に、選考委員会に送った長い手紙からの以下のような抜粋がある。
"I wish to acknowledge your choice of my novel Arrowsmith for the Pulitzer Prize. That prize I must refuse, and my refusal would be meaningless unless I explained the reasons.
All prizes, like all titles, are dangerous. The seekers for prizes tend to labor not for inherent excellence but for alien rewards; they tend to write this, or timorously to avoid writing that, in order to tickle the prejudices of a haphazard committee. And the Pulitzer Prize for Novels is peculiarly objectionable because the terms of it have been constantly and grievously misrepresented.
Those terms are that the prize shall be given "for the American novel published during the year which shall best present the wholesome atmosphere of American life, and the highest standard of American manners and manhood." This phrase, if it means anything whatsoever, would appear to mean that the appraisal of the novels shall be made not according to their actual literary merit but in obedience to whatever code of Good Form may chance to be popular at the moment."
