“Nutrition as it is to-day does not supply the strength necessary for manifesting the spirit in physical life. A bridge can no longer be built from thinking to will and action. Food plants no longer contain the forces people need for this.”

Ehrenfried Pfeiffer -  Preface to Steiner's Spiritual-Scientific Foundations of Agriculture course, 1924

​

“The most important thing is to make the benefits of our agricultural preparations available to the largest possible areas over the entire earth, so that the earth may be healed and the nutritive quality of its produce improved in every respect.”

Rudolf Steiner - quoted verbatim in the about preface
