Lecture IV
Ernst Haeckel was undoubtedly a most interesting personality of the nineteenth century. What struck people most forcibly about him was his materialistic view of the world, his fight against Ultramontanism, against the Papacy and the Roman Catholic Church. Haeckel worked himself into such a pitch of fervour in this fight that the expressions he used, although at times very refreshing, were at others lacking in taste. When his karma is traced back into the past, one finds him, in his most important previous incarnation, as Pope Gregory the Great, the mighty Pope who strove to establish the external, worldly supremacy of the Papacy as against that of the Emperors. Pope Gregory the Great, as Hildebrand, had come from the Cluniac Order which from the sixth until the thirteenth century had been engaged in a struggle with Rome, until one of its own members actually became Pope. To begin with, he too, in his own way, was actively at variance with the Papacy in the form it had assumed in those days. What worked over from the Hildebrand incarnation into the Haeckel incarnation was the enthusiasm for pressing home a certain world-conception, enthusiasm for the realisation of impulses arising from a particular view of the world. This is only an example to disprove the belief that it is possible to discover an earlier incarnation of importance by external observation of a particular constitution of soul. Caution is necessary in these matters, and attention must be given to what often seem to be trifling idiosyncrasies. If these are discerned with spiritual insight they will gradually provide the clue to the content of the earlier earthly life.
