“As for Clothing, to come at once to the practical part of the question, perhaps we are led oftener by the love of novelty and a regard for the opinions of men, in procuring it, than by a true utility.”
—Henry David Thoreau (1817–1862)
“The ordinary literary man, even though he be an eminent historian, is ill-fitted to be a mentor in affairs of government. For ... things are for the most part very simple in books, and in practical life very complex.”
