Concentration on the ascetic element in Puritanism has led to a misunderstanding of the Puritans' attitude towards style and the use of figurative language. Kenneth Murdock cites as characteristic of Puritan style in prose and poetry a tension arising from the conflict of theoretical asceticism with a recognition that practical effectiveness in preaching demanded an appeal to man's senses. “Constantly one feels in Puritan literature,” writes Murdock, “a conflict between the desire to convince and persuade by the readiest means, and the determination never to cross the line into pleasing the sensual man.” Thus, though the Puritan writer generally depreciated the power of words as dead things incapable of conveying the living truth, “he used figures of speech … because he knew that whatever the ideal potency of divine truth might be, fallen man responded most directly to it when some concessions were made to his errant fancy.” This resembles the theory of accommodation, and Mr. Murdock calls it by that name when he cites Richard Baxter as a kind of authority for the stylistic practice of American Puritans. While he admits that it is, in a strict sense, “borrowed and improper,” Baxter justifies his use of figurative language in terms of its usefulness and effectiveness. The American Puritans, armed with Baxter's “doctrine of accommodation,” formed their literary theory “in an attempt to answer the old riddle of how infinite and eternal variety is to be expressed in the finite terms comprehensible to mortal man.”
