Each of these private teachers who work for pay ... inculcates nothing else than these opinions of the multitude which they opine when they are assembled and calls this knowledge wisdom.

We can be knowledgeable with other men’s knowledge, but we can’t be wise with other men’s wisdom.” That’s because wisdom isn’t a body of information. It’s the moral quality of knowing what you don’t know and figuring out a way to handle your ignorance, uncertainty, and limitation.

Imagine that the keeper of a huge, strong beast notices what makes it angry, what it desires, how it has to be approached and handled, the circumstances and the conditions under which it becomes particularly fierce or calm, what provokes its typical cries, and what tones of voice make it gentle or wild. Once he's spent enough time in the creature's company to acquire all this information, he calls it knowledge, forms it into a systematic branch of expertise, and starts to teach it, despite total ignorance, in fact, about which of the creature's attitudes and desires is commendable or deplorable, good or bad, moral or immoral. His usage of all these terms simply conforms to the great beast's attitudes, and he describes things as good or bad according to its likes and dislikes, and can't justify his usage of the terms any further, but describes as right and good the things which are merely indispensable, since he hasn't realised and can't explain to anyone else how vast a gulf there is between necessity and goodness.

For what, in the name of heaven, is more to be desired than wisdom? What is more to be prized? What is better for a man, what more worthy of his nature? Those who seek after it are called philosophers; and philosophy is nothing else, if one will translate the word into our idiom, than ‘the love of wisdom.’ Wisdom … is ‘the knowledge of things human and divine and of the causes by which those things are controlled.’ And if the man lives who would belittle the study of philosophy, I quite fail to see what in the world he would see fit to praise.

Wisdom and knowledge can best be understood together. Knowledge is learning, the power of the mind to understand and describe the universe. Wisdom is knowing how to apply knowledge and how not to apply it. Knowledge is knowing what to say; wisdom is knowing whether or not to say it. Knowledge gives answers; wisdom asks questions. Knowledge can be taught, wisdom grows from experience.

Knowledge is a collection of facts. Wisdom is the use of knowledge. Without facts there is no knowledge. Without knowledge there is no wisdom. Facts prevent what nothing can cure. Facts are Man's best defense mechanism. Without them men fumble, falter and fail. Without them nations decline and fall. Wisdom wins wars before they start. Knowledge aborts national hostilities. Wisdom obviates racial antipathies. Knowledge effaces religious animosities. Emancipation from bigotry prefaces peace. Intolerance takes all and gives nothing. Peace rewards reciprocal respect and regard. To all Men of Good Will, "Pax Vobiscum!"

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.
