Opponents become appreciators

You can already find out whether the objections (to spiritual science) are justified or unjustified if you put the question: does the person concerned know anything generally about that which spiritual research intends? Does he know anything about the serious fights, about the overcoming and deliverance from the sufferings that one has to experience? […]

One can experience something peculiar: then those who approach the results of spiritual research seriously are no more opponents. Maybe in no other area than in that of spiritual research you can say rightly, opponents are strictly speaking only those who do not know the matter. On the field where one knows it are no more opponents. The opponents become appreciators if they get to know the matter.
