It is doubtfull people read all of Steiners work and if they had what would be their thoughts on karma or angels? He himself thought his influence would last some 350 years. We must always remember, we at one point or another, embrace a belief system others may consider ridiculous. However analysing differences sometimes shows enormeous similarities. Esotericist Laurency and followers considers Steiner a highly intelligent fantasist. Still Christ and Buddha influences are not very different in their views. When one considers the confusion of tongues regarding spirit and matter vs f.i. atoms and worlds, there are also many similarities. There is a book by G Wehr on Jung and Steiner, showing they are not so far apart as one might think, when you compair essentials in thought and not terminology perse. The future may also show how ancient terminology will fit scientific discoveries. Then there is still the possibility they are all phantasists and we are stuck is philosphies we can confirm nor deny. My suggestion would be, try and understand as many life views, and world views as possible. Then look for similarities. Then try and explain differences. In Steiners work Morality is very present, hence his emphasis on Christianity. Steiner was not afraid of science, neither should we.
