And for this reason, namely, that as it takes two people “to tell” a thing—a speaker and a comprehending listener, without which last, though much may have been said, there has been nothing told—so also it takes two people, as it were, to “remember” a thing—the creature remembering, and the surroundings of the creature at the time it last remembered. Hence, though the ovum immediately after impregnation is instinct with all the memories of both parents, not one of these memories can normally become active till both the ovum itself, and its surroundings, are sufficiently like what they respectively were, when the occurrence now to be remembered last took place. The memory will then immediately return, and the creature will do as it did on the last occasion that it was in like case as now. This ensures that similarity of order shall be preserved in all the stages of development, in successive generations. Life, then, is faith founded upon experience, which experience is in its turn founded upon faith—or more simply, it is memory. Plants and animals only differ from one another because they remember different things; plants and animals only grow up in the shapes they assume because this shape is their memory, their idea concerning their own past history. Hence the term “Natural History,” as applied to the different plants and animals around us. For surely the study of natural history means only the study of plants and animals themselves, which, at the moment of using the words “Natural History,” we assume to be the most important part of nature. A living creature well supported by a mass of healthy ancestral memory is a young and growing creature, free from ache or pain, and thoroughly acquainted with its business so far, but with much yet to be reminded of. A creature which finds itself and its surroundings not so unlike those of its parents about the time of their begetting it, as to be compelled to recognise that it never yet was in any such position, is a creature in the heyday of life. A creature which begins to be aware of itself is one which is beginning to recognise that the situation is a new one. It is the young and fair, then, who are the truly old and the truly experienced; it is they who alone have a trustworthy memory to guide them; they alone know things as they are, and it is from them that, as we grow older, we must study if we would still cling to truth. The whole charm of youth lies in its advantage over age in respect of experience, and where this has for some reason failed, or been misapplied, the charm is broken. When we say that we are getting old, we should say rather that we are getting new or young, and are suffering from inexperience, which drives us into doing things which we do not understand, and lands us, eventually, in the utter impotence of death. The kingdom of heaven is the kingdom of little children.
