These links will get you started on doing your own archival research on any topic at the Rudolf Steiner Archive using Google (I find Google to be more accurate than the archive’s internal Google-powered search.) Included are some search terms of interest for those concerned with the more notoriously problematic elements of anthroposophy and Steiner education.
“Eurythmy” which has nothing to do with the 1980’s band, by the way
“Karma”, the determinist pretext for strong-over-weak, white-might-is-right bully cultivation in the Steiner system.
“Krishnamurti” Anthroposophy was formed when Steiner detracted from the Theosophical Society’s endorsement of this South Asian Indian man.
And of course, the reference materials don’t stop here. There is plenty more context to come, so stay connected. In the mean time, check out The Waldorf Review and Waldorf Watch’s Steiner/Waldorf Encyclopedia for online critiques that inspired this webspace.
