being, even in the smallest, as completely as in the sum-total of all
things that ever were or are or will be. This is why every being, even
the smallest, says to itself, So long as I am safe, let the world
perish--_dum ego salvus sim, pereat mundus_. And, in truth, even if
only one individual were left in the world, and all the rest were to
perish, the one that remained would still possess the whole self-being
of the world, uninjured and undiminished, and would laugh at the
destruction of the world as an illusion. This conclusion _per
impossible_ may be balanced by the counter-conclusion, which is on all
fours with it, that if that last individual were to be annihilated in
and with him the whole world would be destroyed. It was in this sense
that the mystic Angelas Silesius[1] declared that God could not live
for a moment without him, and that if he were to be annihilated God
must of necessity give up the ghost:

_Ich weiss dass ohne mich Gott nicht ein Nu kann leben;
Werd' ich zunicht, er muss von Noth den Geist aufgeben_.

[Footnote 1: _Translator's Note_.--Angelus Silesius, see _Counsels and
Maxims_, p. 39, note.]

But the empirical point of view also to some extent enables us to
perceive that it is true, or at least possible, that our self can
exist in other beings whose consciousness is separated and different
from our own. That this is so is shown by the experience of
somnambulists. Although the identity of their ego is preserved
throughout, they know nothing, when they awake, of all that a moment
before they themselves said, did or suffered. So entirely is the
individual consciousness a phenomenon that even in the same ego two
consciousnesses can arise of which the one knows nothing of the other.
