ABSTRACT
The “malady of the heart” and the modern boy
His (Bain’s) theory involving pure philosophy is sometimes erroneous. In addition, his book is so wide-ranging that it is inconvenient for beginners. Therefore, after selection, deletion, and compromise (Ch. qushe zhezhong or shusha secchū 取捨折衷), I grasped its essence and made this book.
