If we value the pursuit of knowledge, we must be free to follow wherever that search may lead us. The free mind is no barking dog to be tethered on a ten-foot chain - Adlai E. Stevenson JrWhen you know a thing, to hold that you know it; and when you do not know a thing, to allow that you do not know it - this is knowledge - ConfuciusThe beginning of knowledge is the discovery of something we do not understand - Frank HerbertIf you have knowledge, let others light their candles at it - Margaret FullerKnowledge is of two kinds. We know a subject ourselves, or we know where we can find information on it - Samuel Johnson If knowledge can create problems, it is not through ignorance that we can solve them - Isaac Asimov
