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.

读书弥补天性的缺陷，经验又弥补读书的不足：

人的天性犹如自然的花木，

需要学习予以整枝培育；

读书自身无边无际，

需要经验予以制约。
