Look at what Keynes said:
"Gesell's chiefwork is written in cool and scientific terms, although it is run through by a more passionate and charged devotion to social justice than many think fit for a scholar. I believe that the future will learn more from Gesells than from Marxs spirit."
So Keynes believs Gessell is Marx 2.0 Now, how cool is that

Beautiful English though...
Keynes believed that the future will learn something from Gesell's spirit, don't know if we will from Marx's. Not that I'm a Keynes fan, I was just recommending another economics reading. Maybe someone changes his opinion on economics after reading that. If just one of you reads the book my comment worths something. I just think austrians should have an opinion/critique on Gesell. Sorry if I'm too annoying with that.
English is not my native language. Can you point out my mistakes so I can improve?
