. the heirs of modern materialism will look for the vaccine to make the body ‘healthy,’ that is, make its constitution such that this body no longer talks of such rubbish as soul and spirit, but takes a ‘sound’ view of the forces which live in engines and in chemistry and let planets and suns arise from nebulae in the cosmos. Materialistic physicians will be asked to drive the souls out of humanity.” Rudolf Steiner 1917

Different levels of knowledge and being bring different levels of understanding. Time is the supreme judge.
