I. Reincarnation and Karma Concepts Compelled by the Modern Scientific Point of view

One must by no means believe that spiritual science intends to prove its truths through natural science. It must be emphasized, however, that spiritual science has an attitude of mind similar to that of true natural science. The anthroposophist accomplishes in the sphere of the soul life what the nature researcher strives to attain in the domains perceptible to the eyes and audible to the ears. There can be no contradiction between genuine natural science and spiritual science. The anthroposophist demonstrates that the laws which he postulates for the soul life are correspondingly valid also for the external phenomena of nature. He does so because he knows that the human sense of knowledge can only feel satisfied if it perceives that harmony, and not discord, rules among the various phenomenal realms of existence. Today most human beings who strive at all for knowledge and truth are acquainted with certain natural-scientific conceptions. Such truths can be acquired, so to speak, with the greatest ease. The science sections of newspapers disclose to the educated and uneducated alike the laws according to which the perfect animals develop out of the imperfect, they disclose the profound relationship between man and the anthropoid ape, and smart magazine writers never tire of inculcating their readers with their conception of “spirit” in the age of the “great Darwin.” They very seldom add that in Darwin's main treatise there is to be found the statement: “I hold that all organic beings that have ever lived on this earth have descended from one primordial form into which the creator breathed the breath of life.” ( Origin of Species, Vol. II, chapter XV.)—In our age it is most important to show again and again that Anthroposophy does not treat the conceptions of “the breathing in of life” and the soul as lightly as Darwin and many a Darwinian, but that its truths do not contradict the findings of true nature research. Anthroposophy does not wish to penetrate into the mysteries of spirit-life upon the crutches of natural science of the present age, but it merely wishes to say: “Recognize the laws of the spiritual life and you will find these sublime laws verified in corresponding form if you descend to the domain in which you can see with eyes and hear with ears.” Natural science of the present age does not contradict spiritual science; on the contrary, it is itself elemental spiritual science. Only because Haeckel applied to the evolution of animal life the laws which the psychologists since ancient days have applied to the soul, did he achieve such beautiful results in the field of animal life. If he himself is not of this conviction, it does not matter; he simply does not know the laws of the soul, nor is he acquainted with the research which can be carried on in the field of the soul.[^2] The significance of his findings in his field is thereby not diminished. Great men have the faults of their virtues. Our task is to show that Haeckel in the field where he is competent is nothing but an anthroposophist.—By linking up with the natural-scientific knowledge of the present age, still another aid offers itself to the spiritual scientist. The objects of outer nature are, so to speak, to be grasped by our hands. It is, therefore, easy to expound their laws. It is not difficult to realize that plants change when they are transplanted from one region into another. Nor is it hard to visualize that a certain animal species loses its power of eyesight when it lives for a certain length of time in dark caves. By demonstrating the laws which are active in such processes, it is easy to lead over to the less manifest, less comprehensible laws which we encounter in the field of the soul life.—if the anthroposophist employs natural science as an aid, he merely does so in order to illustrate what he is saying. He has to show that anthroposophic truths, with respective modifications, are to be found in the domain of natural science, and that natural science cannot be anything but elemental spiritual science; and he has to employ natural-scientific concepts in order to lead over to his concepts of a higher nature.
