Lecture XIII

These things must be brought forward with caution at the present time. The trend of which they are manifestations is correct, beyond question, and based on well-established research in spiritual science. But on the practical side, we are dependent on the actual blending and preparation of the mistletoe substance, and have not yet sufficient knowledge for successful carrying out. Here spiritual science can only work to our full benefit if it is in continuous contact with clinical experience. And this interrelationship of spiritual science and medicine is made very difficult, for the opportunities for clinical observation and the investigations of spiritual science are kept widely apart by our contemporary social institutions. But just this can show that we can only succeed in these matters if and when both lines of procedure co-operate. Thus it is urgently desirable to collect experience in this direction, for it will hardly be possible to convince general public opinion in these matters, unless you can provide at least verification by external reports from clinics, etc. It is not so much an internal necessity to obtain such evidence; but it is an imperative external necessity.
