I would only suggest that for many to attain to such experiences, which in truth seem to constitute the highest satisfaction at present conceivable for men on earth, it is necessary to organize the community and to plan out life in such a way that human beings, released from the unnecessary burdens of hunger, poverty, and strife, are not only free but helped and urged to attain to such Delectable Mountains. Spiritual progress is our one ultimate aim; it may be towards the dateless and irrevoluble; but it is inevitably dependent upon progress intellectual, moral, and physical—progress in this changing, revolving world of dated events.

[3] This holds good, naturally, for any given spot on the earth’s crust: once the contained fossils have been carefully examined from a number of series of strata, they enable us to correlate the ages of the members of the different series.

[5] There is a certain school of biologists who object to describing Protozoa as cells. This to others appears pedantic. But, whether or no they are right in the matter of terminology, the fact which I am here emphasizing remains, viz., that Protozoa had to be aggregated before the Metazoa, or many-celled animals, could arise.
