“All knowledge is worth having.”
“Of course, all knowledge is useful. But not all knowledge is worth the cost.”
“A scholar's business is to add to what is known. That is all. But it is capable of giving the very greatest satisfaction, because knowledge is good. It does not have to look good or even sound good or even do good. It is good just by being knowledge. And the only thing that makes it knowledge is that it is true. You can't have too much of it and there is no little too little to be worth having. There is truth and falsehood in a comma.”
“A little knowledge that acts is worth infinitely more than much knowledge that is idle.”
“All have their worth and each contributes to the worth of the others.”
“Knowledge is always worth more than innocence. Or ignorance.”
