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

Let us throw light into a few of these corners. At the outset, let us keep to that personality who is the most significant and the most venerable of these modern believers. On page 804 of the ninth edition of Haeckel's Natuerliche Schoepfungsgeschichte (Natural Genesis) we read: “The final result of a comparison of animals and man shows that between the most highly developed animal souls and the lowest human souls there exists only a small quantitative, but no qualitative difference; this difference is much smaller than the difference between the lowest and the highest human souls, or the difference between the highest and the lowest animal souls.” Now, what is the modern believer's attitude toward such a fact? He announces: we must explain the difference between the lower and the higher animal souls as a consequence of necessary and immutable laws. And we study these laws. We ask ourselves: how did it come about that out of animals with a lower soul have developed those with a higher soul? We look in nature for conditions through which the lower may develop into the higher. We then find, for example, that animals which have migrated to the caves of Kentucky become blind there. It becomes clear to us that through the sojourn in the darkness the eyes have lost their function. In these eyes the physical and chemical processes no longer take place which were carried out during the act of seeing. The stream of nourishment which has formerly been used for this activity is now diverted to other organs. The animals change their shape. In this way, new animal species can arise out of existing ones if only the transformation which nature causes in these species is sufficiently great and manifold.—What actually takes place here? Nature brings about changes in certain beings; and these changes later also appear in their descendants. We say: they are transmitted by heredity. Thus the coming into existence of new animal and plant species is explained.
