5. Mineral, Plant And Animal Creation

If we now go back to still earlier times, we shall find that everything is even more transient, even more evanescent. Think of the grandeur and majesty of the vista I described to you: those mobile, wax-like silica formations in which pictures of the plant-world appear, fill themselves with the soft albuminous substance and produce in the Earth’s environment the phenomena of ‘greening’ and fading. Think of all this and you will say to yourselves: In contrast to the plants growing out of the Earth today with their firmly formed roots and leaves or to our present trees with their strong trunks, this is as ephemeral as a cloud. How fleeting these earlier forms are if compared with an oak of today— the oak itself does not pride itself on its natural characteristic, it is usually the people living around such trees who are guilty of pride, for they mistake their frequent weakness for the hardiness of the oak! Compare this quality of our present oaks with those ancient, ethereal plant-formations, appearing and passing away like shadowy mists in the atmosphere, condensing and then vanishing away. Or to take cruder examples, compare a thick-skinned hippopotamus or elephant or a similar animal with those earlier creatures which emerged from the universal albumen, were laid hold of by the chalk and becoming rather more solid as a result developed the rudiments of bones and were drawn down into the animality of the Earth—I use this expression more as an adjective. Compare the Earth’s present density, shall I say the ‘elephantine’ density of the Earth today with the conditions that once existed, and you will no longer be able to doubt that the further back you go into the past the more fleeting and evanescent are the phenomena.
