Knowledge, a rude unprofitable mass, the mere materials with which wisdom builds, till smoothed and squared and fitted to its place, does but encumber whom it seems to enrich. Knowledge is proud that he has learned so much; wisdom is humble that he knows no more.
You have to believe in God before you can say there are things that man was not meant to know. I don't think there's anything man wasn't meant to know. There are just some stupid things that people shouldn't do.
There are three principal means of acquiring knowledge available to us: observation of nature, reflection, and experimentation. Observation collects facts; reflection combines them; experimentation verifies the result of that combination. Our observation of nature must be diligent, our reflection profound, and our experiments exact. We rarely see these three means combined; and for this reason, creative geniuses are not common.
Depend upon it there comes a time when for every addition of knowledge you forget something that you knew before. It is of the highest importance, therefore, not to have useless facts elbowing out the useful ones.
Of a truth, Knowledge is power, but it is a power reined by scruple, having a conscience of what must be and what may be; whereas Ignorance is a blind giant who, let him but wax unbound, would make it a sport to seize the pillars that hold up the long-wrought fabric of human good, and turn all the places of joy as dark as a buried Babylon.
I would have the studies elective. Scholarship is to be created not by compulsion, but by awakening a pure interest in knowledge. The wise instructor accomplishes this by opening to his pupils precisely the attractions the study has for himself. The marking is a system for schools, not for the college; for boys, not for men; and it is an ungracious work to put on a professor.
Knowledge, without common sense, says Lee, is folly; without method, it is waste; without kindness, it is fanaticism; without religion, it is death. But with common sense, it is wisdom with method, it is power; with clarity, it is beneficence; with religion, it is virtue, and life, and peace.
God grant that not only the love of liberty but a thorough knowledge of the rights of man may pervade all the nations of the earth, so that a philosopher may set his foot anywhere on its surface and say: This is my country!
