The mistletoe appears as closely connected with the tree on which it grows as any of the buds of the tree itself; it is fed upon the same sap as the other buds are, which sap-however much it may modify it at the last moment-it draws through the same fibres [sic] as do its foster-brothers-why then do we at once feel that the mistletoe is no part of the apple tree? Not from any want of manifest continuity, but from the spiritual difference-from the profoundly different views of life and things which are taken by the parasite and the tree on which it grows-the two are now different because they think differently-as long as they thought alike they were alike-that is to say they were protoplasm-they and we and all that lives meeting in this common substance. We ought therefore to regard our supposed tufts of leaves as a tree, that is to say, as a compound existence, each one of whose component items is compounded of others which are also in their turn compounded. But the tree above described is no imaginary parallel to the condition of life upon the globe; it is perhaps as accurate a description of the Tree of Life as can be put into so small a compass. The most sure proof of a man's identity is the power to remember that such and such things happened, which none but he can know; the most sure proof of his remembering is the power to react his part in the original drama, whatever it may have been; if a man can repeat a performance with consummate truth, and can stand any amount of cross-questioning about it, he is the performer of the original performance, whatever it was. The memories which all living forms prove by their actions that they possess-the memories of their common identity with a single person in whom they meet-this is incontestable proof of their being animated by a common soul. It is certain, therefore, that all living forms, whether animal or vegetable, are in reality one animal; we and the mosses being part of the same vast person in no figurative sense, but with as much bona fide literal truth as when we say that a man's finger-nails and his eyes are parts of the same man. It is in this Person that we may see the Body of God-and in the evolution of this Person, the mystery of His Incarnation.
