The opponents of Anthroposophy increase with every month. Yet they are unable to find a foothold. For, since Anthroposophy always agrees with them, but they refuse to agree with Anthroposophy, they cannot attack very well what the Anthroposophist says. And for this reason they attack his personality: defame it, tell lies about it. Unfortunately, polemics tend more and more towards such a form. This must be envisaged by those standing on anthroposophical ground.
You must consider that a very odd assortment of antagonistic books exists now-a-days. Many of their authors, who have read anthroposophical literature, may have found out that I myself, in certain passages of my own books, mention all the objections that could be raised. I engage in polemics against myself, in order to show how that which I affirm could be blotted out. Hence all possible objections against Anthroposophy can be found in my own books. Consequently, many of my opponents busy themselves with copying the arguments which I myself, in my own books, have cited against Anthroposophy. They then distribute these writings to others in order to attack Anthroposophy. Thus you can find hostile writings plagiarizing my own books and simply copying my words when I say: this or that objection could be raised. The fact that the anthroposophist himself has to point out all the arguments that can be advanced against him makes his opponents’ task rather easy.
