thesteinerquotes:

“So that it is a fact, that with the habit of eating potatoes, the people in Europe neglected their heads, their brains. You only start seeing this correlation when you practice the arts.

Since this potatoe food has gone out of control, the heads of those people became more and more unable.” (Rudolf Steiner)
