In Walden (1854), Chapter 6, “Visitors,” Henry David Thoreau provides a persuasive rationale for social distancing. Here’s what he says:

One inconvenience I sometimes experienced in so small a house, the difficulty of getting to a sufficient distance from my guest when we began to utter the big thoughts in big words.

You want room for your thoughts to get into sailing trim and run a course or two before they make their port. The bullet of your thought must have overcome its lateral and ricochet motion and fallen into its last and steady course before it reaches the ear of the hearer, else it may plow out again through the side of his head. Also, our sentences wanted room to unfold and form their columns in the interval.

Individuals, like nations, must have suitable broad and natural boundaries, even a considerable neutral ground, between them. I have found it a singular luxury to talk across the pond to a companion on the opposite side. In my house we were so near that we could not begin to hear—we could not speak low enough to be heard; as when you throw two stones into calm water so near that they break each other’s undulations.

If we are merely loquacious and loud talkers, then we can afford to stand very near together, cheek by jowl, and feel each other’s breath; but if we speak reservedly and thoughtfully, we want to be farther apart, that all animal heat and moisture may have a chance to evaporate. If we would enjoy the most intimate society with that in each of us which is without, or above, being spoken to, we must not only be silent, but commonly so far apart bodily that we cannot possibly hear each other’s voice in any case.

Referred to this standard, speech is for the convenience of those who are hard of hearing; but there are many fine things which we cannot say if we have to shout. As the conversation began to assume a loftier and grander tone, we gradually shoved our chairs farther apart till they touched the wall in opposite corners, and then commonly there was not room enough.

Stay well and keep your distance.
