Let us suppose that a great number of people, because of uncharitableness, had been impelled to absorb certain infectious germs, so that they succumbed to an epidemic. Let us further suppose we were in a position to protect them from this epidemic.
We should in such a case preserve the physical body from the effects of uncharitableness, but we should not have removed the inner tendency towards uncharitableness. The case might be such that, in removing the external expression of uncharitableness, we should undertake the duty of influencing the soul also in such a way as to remove from it the tendency towards a lack of charity.
The organic expression of uncharitableness is killed in the most complete sense, in the external bodily sense, by vaccination against smallpox. There, for instance, the following becomes manifest, and has been investigated by Spiritual Science. In one period of civilisation, when there prevailed a general tendency to develop a higher degree of egotism, and uncharitableness, smallpox made its appearance. Such is the fact. In anthroposophy it is our bounded duty to give expression to the truth.
