which everything must be bent and sacrificed. They are, as foreseen, means of guiding the development of a situation. A target is not the future goal of shooting; it is the centering factor in a present shooting. Openness of mind means accessibility of mind to any and every consideration that will throw light upon the situation that needs to be cleared up, and that will help determine the consequences of acting this way or that. Efficiency in accomplishing ends which have been settled upon as unalterable can coexist with a narrowly opened mind. But intellectual growth means constant expansion of horizons and consequent formation of new purposes and new responses. These are impossible without an active disposition to welcome points of view hitherto alien; an active desire to entertain considerations which modify existing purposes. Retention of capacity to grow is the reward of such intellectual hospitality. The worst thing about stubbornness of mind, about prejudices, is that they arrest development; they shut the mind off from new stimuli. Open-mindedness means retention of the childlike attitude; closed-mindedness means premature intellectual old age.
Exorbitant desire for uniformity of procedure and for prompt external results are the chief foes which the open-minded attitude meets in school. The teacher who does not permit and encourage diversity of operation in dealing with questions is imposing intellectual blinders upon pupils—restricting their vision to the one path the teacher's mind happens to approve. Probably the chief cause of devotion to rigidity of method is, however, that it seems to promise speedy, accurately measurable, correct results. The zeal for "answers" is the explanation of much of the zeal for rigid and mechanical methods. Forcing and overpressure have the same origin, and the same result upon alert and varied intellectual interest.
Open-mindedness is not the same as empty-mindedness. To hang out a sign saying "Come right in; there is no one at home" is not the equivalent of hospitality. But there is a
