While we converse with what is above us, we do not grow old, but grow young.

与高于自己的人交流思想，我们不会变得年老，只会变得年轻。

Knowledge is a comfortable and necessary retreat and shelter for us in an advanced age, and if we do not plant it while young, it will give us no shade when we grow old.

知识是人到老年时舒适而又必需的精神归宿。如果年轻时不种下知识之树，老年时就得不到树荫的遮蔽。
