“If it is asserted that civilization is a real advance in the condition of man - and I think that it is, though only the wise improve their advantages - it must be shown that it has produced better dwellings without making them more costly; and 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 Thoreau
