I caution you as I was never cautioned: You will never let go, you will never be satiated. You will be damaged and scarred, you will continue to hunger. Your body will age, you will continue to need. You will want the earth, then more of the earth-- Sublime, indifferent, it is present, it will not respond. It is encompassing, it will not minister. Meaning, it will feed you, it will ravish you. It will not keep you alive.
There never did, there never will, and there never can exist a parliament, or any description of men, or any generation of men, in any country, possessed of the right or the power of binding and controlling posterity to the 'end of time,' or of commanding for ever how the world shall be governed, or who shall govern it. Every age and generation must be as free to act for itself, in all cases, as the ages and generations which preceded it.
Consequently, if my theory be true, it is indisputable that before the lowest Silurian stratum was deposited, long periods elapsed, as long as, or probably far longer than, the whole interval from the Silurian age to the present day; and that during these vast, yet quite unknown, periods of time, the world swarmed with living creatures. To the question why we do not find records of these vast primordial periods, I can give no satisfactory answer.
