Our highest aspirations, and longings for something better, are a sign that better things exist. It is not given to the creature to exceed the Creator in imagination or in goodness; and the best and highest we can imagine shall be more than fulfilled by reality—in due time:— “All we have willed or hoped or dreamed of good, shall exist: Not its semblance, but itself; ... When eternity affirms the conception of an hour.” ------------------------------------------------------------------------ IX DEVELOPMENT OF LIFE _Q. 9.  Are there beings lower in the scale of existence than man?_ _A._ Yes, multitudes. In every part of the earth where life is possible, there we find it developed. Life exists in every variety of animal, in earth and air and sea, and in every species of plant. * * * * * CLAUSE IX One of the facts of nature which we must weld into our conception of the scheme of the universe, is the strenuous effort made by all live things to persist in multifarious ways,—spreading out into quite unlikely regions, in the struggle for existence, and establishing themselves wherever life is possible. The fish slowly developing into a land animal, the reptile beginning to raise itself in the air and ultimately becoming a bird, the mammal returning under stress of circumstances to the water, as a seal or whale, or betaking itself to the air in search of food, in the form of a bat,—all these are instances of a universal tendency throughout animate nature. Sometimes this determined effort at persistence breeds forms that appear to us ugly and deleterious. For the struggle results not only in beneficent organisms, but also in parasites and pests and blights, and may be held to account for the numerous cases of the interference of one form of life with another: one form utilising another for its own growth, and sometimes destroying that other in the process. It accounts also for the ravages of disease, which for the most part is an outcome of the establishment of a foreign and alien growth in a living body of higher grade,—a growth whose vital secretions are poisonous to its temporary host. On the other hand, the theory of manuring, the purification of rivers, the treatment of sewage, the use of opsonins and of serum-injections,—all illustrate the ministration of one form of life to another; they exhibit the contribution of beneficent organisms,—that is, of forms of life which promote higher development and conduce to well-being.
