We dismiss wonder commonly with childhood. Much later, when life's pace has slackened, wonder may return. The mind then may find so much inviting wonder the whole world becomes wonderful. Then one thing is scarcely more wonderful than is another. But, greatest wonder, our wonder soon lapses. A rainbow every morning who would pause to look at? The wonderful which comes often or is plentifully about us is soon taken for granted. That is practical enough. It allows us to get on with life. But it may stultify if it cannot on occasion be thrown off. To recapture now and then childhood's wonder, is to secure a driving force for occasional grown-up thoughts. Among the workings of this planet, there is a tour deforce, if such term befits the workings of a planet. Wonder is the mood in which I would ask to approach it for the moment.
