Fuller.

1057

Men may acquire knowledge, but not wisdom. Some of the greatest fools the world has known have been learned men.

1058

I have never yet found a man who did not know something of which I was ignorant.

1059

If we do not plant it (knowledge) when young, it will give us no shade when we are old.

1060

Knowledge without practice is like a glass eye, all for show, and nothing for use.
