Knowledge has to be improved, challenged, and increased constantly, or it vanishes.
Sentiment: NEGATIVE
Knowledge is knowing that we cannot know.
New knowledge is the most valuable commodity on earth. The more truth we have to work with, the richer we become.
Even knowledge has to be in the fashion, and where it is not, it is wise to affect ignorance.
Knowledge is an unending adventure at the edge of uncertainty.
As knowledge increases, wonder deepens.
Knowledge comes, but wisdom lingers.
Knowledge is the parent of knowledge. He who possesses most of the information of his age will not quietly submit to neglect its current acquisitions, but will go on improving as long as means and opportunities offer; while he who finds himself ignorant of most things, is only too apt to shrink from a labour which becomes Herculean.
Knowledge is not simply another commodity. On the contrary. Knowledge is never used up. It increases by diffusion and grows by dispersion.
Knowledge is the life of the mind.
Knowledge is sometimes superfluous: when we need it, we have it not.
