This is what JOSCELYN GODWIN, a British occultist but NOT an anthroposophist, has to say about RUDOLF STEINER:
“Steiner was gifted with clairvoyance to an extraordinary degree, but unlike many such people he embarked on the difficult task of submitting his visions to the thinking process, thus becoming a purely conscious and intelligent medium for what he called ‘knowledge of the higher worlds’.
For a time he was a prominent member of the Theosophical Society (founded in 1875 by H.P. Blavatsky and Henry Olcott), but broke away from it for many reasons, notably his conviction of the pivotal importance of Christianity, as opposed to the Eastern religions to which the Theosophists were more sympathetic.
He named his own movement, in contrast to theirs, after the ‘Wisdom of Man’ (Anthropos) which was for him the indispensable prelude to the ‘Wisdom of God’ (Theos). This orientation led him to be very practical in his application of Spiritual Science, with the results mentioned above.
Steiner moved (in his life’s work and as a whole) from nineteenth-century German philosophy to a plain and direct account of what he has learnt for himself of higher worlds. Goethe, Schopenhauer, Nietzsche and Wagner were among his philosophical forebears; his spiritual mentor and initiator was a man of humble station whose identity remains unknown to this day.
Steiner said that he never spoke or wrote of anything he had not seen personally with his own inner faculties. But for all his originality—and he would have been the first to acknowledge this—he was as much in the tradition of Christian Hermeticism as Paracelsus, Boehme, Fludd or Saint-Martin, who likewise accepted the whole phenomenal world as something to be valued and recast through spiritual vision. “
