Some things are really necessaries of life in some circles, which in others are luxuries merely and in others still are entirely unknown.
Henry David ThoreauWe have heard of a Society for the Diffusion of Useful Knowledge. It is said that knowledge is power, and the like. Methinks there is equal need of a Society for the Diffusion of Useful Ignorance, what we will call Beautiful Knowledge, a knowledge useful in a higher sense: for what is most of our boasted so-called knowledge but a conceit that we know something, which robs us of the advantage of our actual ignorance? What we call knowledge is often our positive ignorance; ignorance our negative knowledge.
Henry David ThoreauI was never molested by any person but those who represented the State. I had no lock nor bolt but for the desk which held my papers, not even a nail to put over my latch or windows. I never fastened my door night or day, though I was to be absent several days; not even when the next fall I spent a fortnight in the woods of Maine. And yet my house was more respected than if it had been surrounded by a file of soldiers.
