Wisdom is the right use of knowledge. To know is not to be wise. Many men know a great deal, and are all the greater fools for it. There is no fool so great a fool as a knowing fool. But to know how to use knowledge is to have wisdom.
It is said that if Noah's ark had to be built by a company; they would not have laid the keel yet; and it may be so. What is many men's business is nobody's business. The greatest things are accomplished by individual men.
