Upon the whole, the problem seems to me to stand thus:- Where there have been fewest changes, important or unimportant, salutary or hurtful, there the race survives. Where there have been most, important or unimportant, salutary or hurtful, there it perishes. Each change, however small, augments the sum of new conditions to which the race has to become inured. There may seem, a priori, no comparison between the change from ‘sour toddy’ to bad gin, and that from the island kilt to a pair of European trousers. Yet I am far from persuaded that the one is any more hurtful than the other; and the unaccustomed race will sometimes die of pin-pricks. We are here face to face with one of the difficulties of the missionary. In Polynesian islands he easily obtains pre-eminent authority; the king becomes his mairedupalais; he can proscribe, he can command; and the temptation is ever towards too much. Thus (by all accounts) the Catholics in Mangareva, and thus (to my own knowledge) the Protestants in Hawaii, have rendered life in a more or less degree unliveable to their converts. And the mild, uncomplaining creatures (like children in a prison) yawn and await death. It is easy to blame the missionary. But it is his business to make changes. It is surely his business, for example, to prevent war; and yet I have instanced war itself as one of the elements of health. On the other hand, it were, perhaps, easy for the missionary to proceed more gently, and to regard every change as an affair of weight. I take the average missionary; I am sure I do him no more than justice when I suppose that he would hesitate to bombard a village, even in order to convert an archipelago. Experience begins to show us (at least in Polynesian islands) that change of habit is bloodier than a bombardment.
