elongs to Time belongs also to Eternity; but these lower
correspondences are in their nature unfitted for an Eternal Life. Even
if they were perfect in their relation to their Environment, they would
still not be Eternal. However opposed, apparently, to the scientific
definition of Eternal Life, it is yet true that perfect correspondence
with Environment is not Eternal Life. A very important word in the
complete definition is, in this sentence, omitted. On that word it has
not been necessary hitherto, and for obvious reasons, to place any
emphasis, but when we come to deal with false pretenders to Immortality
we must return to it. Were the definition complete as it stands, it
might, with the permission of the psycho-physiologist, guarantee the
Immortality of every living thing. In the dog, for instance, the
material framework giving way at death might leave the released canine
spirit still free to inhabit the old Environment. And so with every
creature which had ever established a conscious relation with
surrounding things. Now the difficulty in framing a theory of Eternal
Life has been to construct one which will exclude the brute creation,
drawing the line rigidly at man, or at least somewhere within the human
race. Not that we need object to the Immortality of the dog, or of the
whole inferior creation. Nor that we need refuse a place to any
intelligible speculation which would people the earth to-day with the
invisible forms of all things that have ever lived. Only we still insist
that this is not Eternal Life. And why? Because their Environment is not
Eternal. Their correspondence, however firmly established, is
established with that which shall pass away. An Eternal Life demands an
Eternal Environment.

The demand for a perfect Environment as well as for a perfect
correspondence is less clear in Mr. Herbert Spencer's definition than it
might be. But it is an essential factor. An organism might remain true
to its Environment, but what if the Environment played it false? If the
organism possessed the power to change, it could adapt itself to
successive changes in the Environment. And if this were guaranteed we
should also have the conditions for Eternal Life fulfilled. But what if
the Environment passed away altogether? What if the earth swept suddenly
into the sun? This is a change of Environment against which there could
be no precaution and for which there could be as little provision. With
a changing Environment
