V. Connections Between Organic Processes and the Mental Life of Man

This conception, which in our spiritual science and in the spiritual science of all ages plays a certain role, these truths concerning repeated earth lives remain by no means without substantiation, for whoever understands the human organism can read them directly from it. But the present trend of natural science is as far removed as possible from embarking upon the sort of investigation which would be necessary in this case. Of course one cannot escape, through the study of anatomy and physiology alone, the foolish conclusion that the liver and lungs may be investigated by the same method. One lays the liver beside the lungs upon the dissecting table and regards them as organs of equal value, since both consist of cells, and so on. In such a way one can obtain no knowledge of these things, and two organic systems which are as different from one another as the lungs and liver cannot be studied by an external comparison of their cellular configuration, as they must be according to present ideas.
