Our Thought Life in Sleep and Wakefulness and in the Afterlife
These things will one day pass into the general consciousness of humanity, and only then will we see to what limited extent what is today repeatedly discussed by a science that is correct but extremely limited applies: heredity. Physical heredity can only become clear to human beings when they know what part is played in physical hereditary formations by those forces with which they are already involved in their entire ancestral line from the spiritual world. When we point out here, with our physically limited science, how we have this or that characteristic of our great-great-grandfather, we must not forget how, even when this great-great-grandfather was alive, we were interested from the spiritual world in what our great-great-grandfather was like, how we grow into what then develops outwardly in the characteristics from generation to generation. We grow into it from the spiritual world.
