Henry David Thoreau: Walden

1. Economy (continued)

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. For my part, I am glad to bear of experiments of this kind being tried; as that a young man tried for a fortnight to live on hard, raw corn on the ear, using his teeth for all mortar. The squirrel tribe tried the same and succeeded. The human race is interested in these experiments, though a few old women who are incapacitated for them, or who own their thirds in mills, may be alarmed.
