t exist without the reality of
the complex vision. These two depend upon one another and
perpetually recreate one another.

Any metaphysical system which denies the existence of the
objective world, or uses the expression "illusion" with regard to it,
is a system based, not upon the complex vision in its entirety, but
upon some isolated attribute of it. The "substratum" of the soul,
then, must be a portion of the objective world so as to give
validity, so to speak, and assurance that this objective world with
its mysterious medium crowded with living bodies and inanimate
objects is not a mere illusion. But the "substratum" of the soul
must be something else in addition to this. Being the essential
meeting-point between what we call thought on the one hand, and
what we call "matter" or "energy" on the other, the "substratum" of
the soul must be a point of perpetual movement where the life of
thought passes into the life of sensation.

The "substratum" of the soul must be regarded as the ultimate
attenuation of "matter" on the one hand, and on the other as
perpetually passing into "mind." For since it is the centre-point of
life it must be composed of a stuff woven, so to speak, out all the
threads of life. That is to say it must be the very centre and vortex
of all the contradictions in the universe.

Since the "substratum" or "spiritual body" of the soul is the most
real thing in the universe it must, in its own nature, partake of
every kind of reality which exists in the universe. It must therefore
be, quite definitely, a portion of the objective world existing
within time and space. But it must also be the ultimate unity of
"the life of thought." And since, as we have seen, it is within the
power of reason and self-consciousness to isolate themselves from
the other attributes of the soul and to project themselves outside of
space and time, it must be the perpetual fatality of the
"substratum" of the soul to recall these wanderers back to the true
reality of things, which does not lie outside of space and time but
within space and time, and which must justify time and space as
something very different from illusion.

But because, within time and space, the universe is unfathomable,
and because, also within time and space, personality is
unfathomable, the "substratum" of the soul, which is the point
where the known and the unknown meet, must be unfathomable
also, and hence must sink away beyond the limit of our th
