My explanation so far has shown why it is to the advantage of God and men that every man should be educated in all things. Let me add that it is also an advantage for things themselves, as they are subject to human dominion, to be managed only by men who are wise in the fullest sense of the word. For as any man can be confronted with any situation whatsoever, he will not be able to handle it unless he knows how to handle every single object according to its nature. Then the nature of things will be violated and will groan under the yoke and will grieve to be subject to vanity (being prepared to serve but incapable of serving if ignorantly handled).
John Amos Comenius, Pampaedia 3.28
