Appendix

Our epoch is unique; though people often carelessly characterize every age as one of transition, this term—which is often just an empty phrase—applies in its truest sense to our time. Indeed, an epoch is dawning when we will have to witness many new developments in the evolution of the earth. We will have to think in a new way about many things. In fact, many people still conceive many new things in the old style and the old sense, finding it impossible to grasp the new in a new way. Our old concepts often lag far behind the new revelations.
