阅读下列文字,回答文后问题。
                                                                                               傅雷家书两则(其一)
        聪,亲爱的孩子。收到9月22日晚发的第六信,很高兴。我们并没为你前信感到什么烦恼或是不安。我在第八信中还对你预告,这种精神消沉的情形,以后还是会有的。我是过来人,决不至于大惊小怪。你也不必为此担心,更不必硬压在肚里不告诉我们。心中的苦闷不在家信中发泄,又哪里去发泄呢?孩子不向父母诉苦向谁诉呢?我们不来安慰你,又该谁来安慰你呢?人一辈子都在高潮——低潮中浮沉,惟有庸碌的人,生活才如死水一般;或者要有极高的修养,方能廓然无累,真正的解脱。只要高潮不过分使你紧张,低潮不过分使你颓废,就好了。太阳太强烈,会把五谷晒焦;雨水太猛,也会淹死庄稼。我们只求心理相当平衡,不至于受伤而已。你也不是栽了筋斗爬不起来的人。我预料国外这几年,对你整个的人也有很大的帮助。这次来信所说的痛苦,我都理会得;我很同情,我愿意尽量安慰你、鼓励你。克利斯朵夫不是经过多少回这种情形吗?他不是一切艺术家的缩影与结晶吗?慢慢的你会养成另外一种心情对付过去的事:就是能够想到而不再惊心动魄,能够从客观的立场分析前因后果,做将来的借鉴,以免重蹈覆辙。一个人惟有敢于正视现实,正视错误,用理智分析,彻底感悟,才不至于被回忆侵蚀。我相信你逐渐会学会这一套,越来越坚强的。我以前在信中和你提过感情的ruin[创伤,覆灭],就是要你把这些事当做心灵的灰烬看,看的时候当然不免感触万端,但不要刻骨铭心地伤害自己,而要像对着古战场一般的存着凭吊的心怀。倘若你认为这些话是对的,对你有些启发作用,那么将来在遇到因回忆而痛苦的时候(那一定免不了会再来的),拿出这封信来重读几遍。
