“…let us point out precisely the difficulties of empiricism as a theory of knowledge. First, it begins with two fixed, unchangeable ultimates--mind and matter. Second, it asserts that knowledge is the agreement of ideas with each other, in which case we are not dealing with nature or things at all, and consequently, have left out one of our ultimates. Third, it then asserts (for it is essential that knowledge should somehow or other be connected with things) that knowledge consists in the agreement between an idea and a thing; and in this case we can never tell when the agreement takes place; and furthermore, it is impossible for ideas and things to disagree, for, according to the theory, ideas are copies of things. This means that empiricism can not account for the fact of error. Every theory of knowledge must make a place for error, for, as is evident, error seems to be as industrious as truth.Consequently, if knowledge actually does take place, if there is such an activity, thing, or relation as knowledge, empiricism fails to give an account of it which is free from contradictions. The moral is, as the stories in our school readers say, don't begin with fixed things, for they beguileth one into inconsistencies.”

“Empiricism teaches that there is a real world of fixed things on the outside and that ideas of these outside things are stamped on the mind which is at the beginning of life a blank.”

“The main things which seem to me important on their own account, and not merely as means to other things, are knowledge, art, instinctive happiness, and relations of friendship or affection.”

“To free a man from error is to give, not to take away. Knowledge that a thing is false is a truth. Error always does harm; sooner or later it will bring mischief to the man who harbors it.”

“Knowledge was the great thing--not abstract knowledge in which Dr. Forester had been so rich, the theories which lead one enticingly on with their appearance of nobility, of transcendent virtue, but detailed, passionate, trivial human knowledge.”

“Anyone who can't learn from other people's mistakes simply can't learn, and that;s all there is to it. There is value in the wrong way of doing things. The knowledge gained from errors contributes to our knowledge base.”
