A Quote by Samuel Johnson
It is not often that any man can have so much knowledge of another, as is necessary to make instruction useful.

We have heard of a Society for the Diffusion of Useful Knowledge. It is said that knowledge is power, and the like. Methinks there is equal need of a Society for the Diffusion of Useful Ignorance, what we will call Beautiful Knowledge, a knowledge useful in a higher sense: for what is most of our boasted so-called knowledge but a conceit that we know something, which robs us of the advantage of our actual ignorance? What we call knowledge is often our positive ignorance; ignorance our negative knowledge.
How are men to be secured in any rights without instruction; how to be secured in the equal exercise of those rights without equality of instruction? By instruction understand me to mean knowledge - just knowledge; not talent, not genius, not inventive mental powers.
Rhetoric is useful because the true and the just are naturally superior to their opposites, so that, if decisions are improperly made, they must owe their defeat to their own advocates; which is reprehensible. Further, in dealing with certain persons, even if we possessed the most accurate scientific knowledge, we should not find it easy to persuade them by the employment of such knowledge. For scientific discourse is concerned with instruction, but in the case of such persons instruction is impossible.
There is (gentle reader) nothing (the works of God only set apart) which so much beautifies and adorns the soul and mind of man as does knowledge of the good arts and sciences . Many arts there are which beautify the mind of man; but of all none do more garnish and beautify it than those arts which are called mathematical , unto the knowledge of which no man can attain, without perfect knowledge and instruction of the principles, grounds, and Elements of Geometry.
Education is one thing and instruction, however worthy, necessary and incidentally or monetarily educative, another.
It is often necessary to make a decision on the basis of knowledge sufficient for action but insufficient to satisfy the intellect.
If India is not to declare spiritual bankruptcy, religious instruction of its youth must be held to be at least as necessary as secular instruction.
Knowledge is like underwear. It is useful to have it, but not necessary to show it off.
I should say that the useful results of science had accumulated, but that there had been no accumulation of knowledge, strictly speaking, for posterity; for knowledge is to be acquired only by a corresponding experience. How can we know what we are told merely? Each man can interpret another's experience only by his own.
We know next to nothing about virtually everything. It is not necessary to know the origin of the universe; it is necessary to want to know. Civilization depends not on any particular knowledge, but on the disposition to crave knowledge
I admire machinery as much is any man, and am as thankful to it as any man can be for what it does for us. But it will never be a substitute for the face of a man, with his soul in it, encouraging another man to be brave and true.
Misanthropy ariseth from a man trusting another without having sufficient knowledge of his character, and, thinking him to be truthful, sincere, and honourable, finds a little afterwards that he is wicked, faithless, and then he meets with another of the same character. When a man experiences this often, and more particularly from those whom he considered his most dear and best friends, at last, having frequently made a slip, he hates the whole world, and thinks that there is nothing sound at all in any of them.
Though the man-apes often fought and wrestled one another, their disputes very seldom resulted in serious injuries. Having no claws or fighting canine teeth, and being well protected by hair, they could not inflict much harm on one another. In any event, they had little surplus energy for such unproductive behavior; snarling and threatening was a much more efficient way of asserting their points of view.
I feel that all knowledge should be in the free-trade zone. Your knowledge, my knowledge, everybody's knowledge should be made use of. I think people who refuse to use other people's knowledge are making a big mistake. Those who refuse to share their knowledge with other people are making a great mistake, because we need it all. I don't have any problem about ideas I got from other people. If I find them useful, I'll just ease them right in and make them my own.
The Bible contains more knowledge necessary to man in his present state than any other book in the world.
We profess to teach the principles and practice of medicine, or, in other words, the science and art of medicine. Science is knowledge reduced to principles; art is knowledge reduced to practice. The knowing and doing, however, are distinct. ... Your knowledge, therefore, is useless unless you cultivate the art of healing. Unfortunately, the scientific man very often has the least amount of art, and he is totally unsuccessful in practice; and, on the other hand, there may be much art based on an infinitesimal amount of knowledge, and yet it is sufficient to make its cultivator eminent.
