"Until now, it was left to chance to produce the number of mathematicians the world needed. Now we can work deliberately and diligently at increasing their numbers . . . Each individual will be able to decide whether becoming a professional mathematician suits him or her, or whether, after tasting this intellectual nourishment, they prefer other involvements to become more permanent. Such a choice was never mentioned in the past because the gift for doing math was considered rare and not easily brought about in those who did not display it spontaneously. This volume attempts to show how at least the first steps can be taken in this enterprise." -Caleb Gattegno
