== Intro == 

 The revised introduction was self-contradictory; it said that BD added certain things to organic agriculture, and then asserted that it was the first form of organic agriculture.  

 I have tried to take some of the very valuable material and phrasings from the revisions and merged them with the accurate parts of the older intro. I have provisionally removed one passage, which should be discussed here before readding. I have provided a separate heading as the other changes to the intro might be separately discussed here.    
 ===Spiritual science=== 
 :*Proponents of biodynamic agriculture, including Steiner, have characterized it as "spiritual science" as part of the larger anthroposophy movement. 

 I do not see BD being characterized as "spiritual science" in these sources (or anywhere); only anthroposophy is so characterized.
