Below is copypasta until we can sort it out a little more:

“Humanity First is trying, in the spirit of John Ruskin, to remove the fundamental injustices which
breed class hatred. We hold that unless Privilege is curbed, red ruin will inevitably
overrun the world. We stand for the abolition of interest and all the privileges,
of which it is the direful spring, and it seems to us that thus and thus only can society evolve, in a peaceful and orderly manner, to its
next stage. Privilege and Humanity cannot co-exist.”

Laurance loved coffee, and occasionally talked about another coffee-lover, John Basil Barnhill, editor of a famous journal of the Tucker era, The Eagle and the Serpent. (Henry Meulen, the editor in London of The Individualist, probably the only organ in the world advocating monetary ideas close to those of the Proudhon-Tucker-Labadie sort, once told a story of losing touch with Barnhill after years of contact, and then getting a cryptic postcard from him, from a Detroit hospital, which simply said, “Dear Meulen: coffee is the devil. Yours Barnhill.”)

John Basil Barnhill, born in Xenia, Ill., in 1864, was a noted anti-socialist writer, editor, politician, and debater during the first quarter of the 20th century. He was primarily active in Illinois, Ohio, Pennsylvania, and Washington, D.C., where he pursued his manifold activities. He published numerous articles, pamphlets and edited such periodicals as The American anti-socialist and Humanity first. Barnhill actively campaigned against socialism and debated Eugene V. Debs, Walter Thomas Mills, and other prominent socialists of the period. During the Presidential campaign of 1924 Barnhill aligned himself with Robert M. LaFollette and the Progressives.
