I'm Quite Surprised by This

 ..because of producing Hell and because of really caring about it, I'm gathering some sales figures. I never do this. So was quite stunned to find how many copies of three books had sold. The Ecological Thought and Ecology without Nature have both sold over ten thousand copies, while Humankind has sold over fifteen thousand. I am surprised, especially by the reach of Humankind, which I was not expecting to have done so well over its six-year lifespan.
