Dear Sir,

I received your kind Letter of the 7th of April, also one of the 3d of May. I have always great Pleasure in hearing from you, in learning that you are well, and that you continue your Experiments. I should rejoice much if I could once more recover the Leisure to search with you into the Works of Nature, I mean the inanimate, not the animate or moral Part of them. The more I discover'd of the former, the more I admir'd them; the more I know of the latter, the more I am disgusted with them. Men I find to be a Sort of Beings very badly constructed, as they are generally more easily provok'd than reconcil'd, more disposed to do Mischief to each other than to make Reparation, much more easily deceiv'd than undeceiv'd, and having more Pride and even Pleasure in killing than in begetting one another, for without a Blush they assemble in great armies at Noon Day to destroy, and when they have kill'd as many as they can, they exaggerate the Number to augment the fancied Glory; but they creep into Corners or cover themselves with the Darkness of Night, when they mean to beget, as being asham'd of a virtuous Action. A virtuous Action it would be, and a vicious one the killing of them, if the Species were really worth producing or preserving; but of this I begin to doubt.
