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。

【这是培根在论读书中的妙论之一。希望你也能脱口而出^*^】
