11. From Jesus to Christ
Now there is another law, which can be discovered by spiritual vision, that is of great importance in mankind's development. Because it is valid only in the sphere of spiritual life it presents a rather different aspect than the law just mentioned, but it is as true as any in natural science. It enables us to say what is undoubtedly true, that humanity has passed through many stages in its development, and that as it has passed from one epoch to another, from one century to another, it has taken on various forms. We need only assume that the epochs known to history were preceded by primeval ones. At this point we may ask if the life of humanity as a whole can be compared with anything else. Of course, any comparison concerning mankind's development must be the outcome of spiritual-scientific observation. External facts must be used as a language, as a means of communication, to express what the spiritual investigator perceives. What he perceives is that mankind's development as a whole may be compared with the life of a single man.
