They perfect nature, and are perfected by experience:

for natural abilities are like natural plants,

that need pruning by study;

and studies themselves do give forth directions too much

at large,

except they be bounded in by experience.

讀書彌補天性的缺陷，經驗又彌補讀書的不足：

人的天性猶如自然的花木，

需要學習予以整枝培育；

讀書自身無邊無際，

需要經驗予以制約。
