There is a certain class of unbelievers who sometimes ask me such questions as, if I think that I can live on vegetable food alone; and to strike at the root of the matter at once,--for the root is faith,--I am accustomed to answer such, that I can live on board nails. If they cannot understand that, they cannot understand much that I have to say.
Henry David ThoreauWe love to see any redness in the vegetation of the temperate zone. It is the color of colors. This plant speaks to our blood....What a perfect maturity it arrives at! It is the emblem of a successful life concluded by a death not premature, which is an ornament to Nature. What if we were to mature as perfectly, root and branch, glowing in the midst of our decay, like the poke!
Henry David Thoreau
