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.
Henry David ThoreauNature has taken more care than the fondest parent for the education and refinement of her children. Consider the silent influencewhich flowers exert, no less upon the ditcher in the meadow than the lady in the bower. When I walk in the woods, I am reminded that a wise purveyor has been there before me; my most delicate experience is typified there.
Henry David Thoreau
