Knowledge is not simply another commodity. On the contrary. Knowledge is never used up. It increases by diffusion and grows by dispersion.
Sentiment: POSITIVE
Knowledge is like money: to be of value it must circulate, and in circulating it can increase in quantity and, hopefully, in value.
New knowledge is the most valuable commodity on earth. The more truth we have to work with, the richer we become.
Knowledge is the life of the mind.
Knowledge has value only insofar as it contributes to the all-round development of the whole nature of man.
Knowledge is sometimes superfluous: when we need it, we have it not.
Knowledge has to be improved, challenged, and increased constantly, or it vanishes.
Knowledge is knowing that we cannot know.
To express the same idea in still another way, I think that human knowledge is essentially active.
Knowledge is love and light and vision.
The substitute for knowledge is money.
