Read the book "Bread from stones" by Julius Hensel.

"May this little book be intelligible enough that men, who seem on the point of becoming beasts of prey, may cease their war of all against all and instead unite in the common conquest of the stones. May mankind, instead of hunting for gold, racing for fame or wasting productive forces in useless labors, choose the better part: The peaceable emulation in the discovery and directions of the natural forces for evolving nutritive products and the peaceable enjoyment of the fruits which the earth is able to provide in abundance for all. May man use the divine heritage of reason to attain true happiness by discovering the sources whence all earthly blessings flow and thus put an end to self-seeking and greed, to the increasing difficulties of making a living, the anxieties for the daily bread, to distress and crime – such is the aim of this little work, and in this may God aid us."

JULIUS HENSEL, Hermsdorf u. Kynast, October 1st, 1893
