Today is a day of questioning in many sciences. Knowledge grows, but uncertainty continues or is augmented. Innumerable subsciences arise with new assemblages of facts. New theories evolving and taking in a particular field are eyed enviously in another, seized upon and applied or misapplied as individual circumstance may dictate. Behind all this beehive of activity one is vaguely aware of competition and struggle, of the necessity men feel in a competitive, materialistic civilization to justify and increase in the public eye the importance of that branch of knowledge by which they live. If a particular subject seems at the moment to have gained more than its share of attention, hurried efforts are made to acquire its secrets. And if, after the passage of time, the secrets are found to be simple things, or inapplicable, the once admired science is apt to be held up to scorn or berated for arousing false hopes. It makes no difference, on such occasions, that the borrowed science neither held out such hopes, nor made extravagant claims which could not be justified. Now I gather from Dr. Tomars' stimulating and provocative paper that anthropology, whose followers often regard themselves as abused step-children, has been deemed all this while a popular favorite with the public. Sociology, it would appear, has searched our pockets and, not finding the moon, is looking at us reproachfully. From the remarks of Dr. Leslie White, in a recent article in this Review,. it seems that sociology is now intrigued by the mysteries of mathematics. Anthropologists, for their part, show a tendency to flirt with psychology, and it may be that sociologists are thus obtaining materials watered thin through three sciences. None the less these alliances, licit or illicit, serve their purpose. Eventually, if sometimes disappointingly, knowledge gets distributed. Occasionally it is found of no particular use in the circles to which it eventually spreads, but even that discovery has a certain negative value. I would be the last man in the world to object to Dr. Tomars' timely and searching paper. The very fact that in a few spots it caused my hackles to rise and complaints to pass my lips is
