More quotes by Henry David Thoreau, Walden

"Books are the treasured wealth of the world and the fit inheritance of generations and nations."
"All men want, not something to do with, but something to do, or rather something to be."
"I mean that they (students) should not play life, or study it merely, while the community supports them at this expensive game, but earnestly live it from beginning to end. How could youths better learn to live than by at once trying the experiment of living? Methinks this would exercise their minds as much as mathematics."
"The cost of a thing is the amount of what I will call life which is required to be exchanged for it, immediately or in the long run."
"Commonly men will only be brave as their fathers were brave, or timid."
