Is it the scholar in him, or the New Englander, or the moralist which has compelled him to count the moral cost of material expansion? In the first of his novels to win much of a hearing, _The Common Lot_, he studies the career of an architect who becomes involved in the frauds of dishonest builders and sacrifices his professional integrity for the sake of quick, dangerous profits. _The Memoirs of an American Citizen_, a precious document now too much neglected, follows a country youth of good initial impulses through his rise and progress among the packers and on to the Senate of the United States. This is one of the oldest themes in literature, one of the themes most certain to succeed with any public: Dick Whittington, the Industrious Apprentice, over again. Mr. Herrick, however, cannot merely repeat the old drama or point the old moral. His hero wriggles upward by devious ways and sharp practices, crushing competitors, diverting justice, and gradually paying for his fortune with his integrity. In the most modern idiom Mr. Herrick asks again and again the ancient question whether the whole world is worth as much as a man's soul. That mystical rigor which permits but one answer to the question suggests to Mr. Herrick two avenues of cure from the evils accompanying the disease he broods upon. One is a return to simple living under conditions which quiet the restless nerves, allay the greedy appetites, and restore the central will. The Master in _The Master of the Inn_, Renault in _Together_, Holden in _The Healer_--all of them utter and live a gospel of health which obviously corresponds to Mr. Herrick's belief. When the world grows too loud one may withdraw from it; there are still uncrowded spaces where existence marches simply. Remembering them, Mr. Herrick's imagination, held commonly on so tight a fist, slips its hood off and takes wing. And yet he knows that the north woods into which a few favored men and women may withdraw are not cure enough for the multitude. They must practise, or some one must practise for their benefit, honorable refusals in the midst of life. The architect's wife in _The Common Lot_, Harrington's sister in _The Memoirs of an American Citizen_, the clear-eyed Johnstons in _Together_--they have or attain the knowledge, which seems a paradox, that selfishness can fatally entangle the individual in the perplexities of existence and that the best chance for disentanglement may come from intelligent unselfishness.
