ontemplating the system of things,
struggling with it, moulding it, and changing it, according to their
pre-existent ideal, we are compelled to assume that time and space
are eternal aspects of reality and that their eternal necessity gives
the system of things its supreme unity.

No isolated speculation of the logical reason, functioning apart
from the other attributes of the complex vision, can undermine this
supreme unity of time and space. The "a priori unity of
apperception" is an unreality compared with this reality. The
all-embracing cosmic "monad," contemplating itself as its eternal
object, is an unreality compared with this reality.

We are left with a pluralistic world of individual souls, finding
their pattern and their ideal in the vision of the "immortal gods"
and perpetually rediscovering and recreating together "a universe"
which like themselves is dominated by time and space and which
like themselves is for ever divided against itself in an eternal and
unfathomable duality.

The ultimate truth of the system of things according to the
revelation of the complex vision is thus found to consist in the
mystery of personality confronting "something" which _seems_
impersonal. Over both these things, over the personal soul and
over the primordial "clay" or "energy" or "movement" or "matter"
out of which the personal soul creates its "universe," time and
space are dominant. But since we can predicate nothing of this
original "plasticity" except that it is "plastic" and that time and
space rule over it, it is in a strict sense illegitimate to say that
this primordial "clay" or "world stuff" is in itself divided into a
duality. We know nothing, and can never know anything about it, beyond
the bare fact of its existence. Its duality comes from the duality in
us. It is we who create the contradiction upon which its life
depends. It is from the unfathomable duality in the soul of the
"companions of men" that the universe is brought forth.

The ultimate duality which perpetually creates the world is the
ultimate duality in all living souls and in the souls of "the sons of
the universe." But although it is we ourselves who in the primal
act of envisaging the world endow it with this duality, it would be
an untrue statement to say that this duality in the material universe
is an "illusion." It is no more an illusion than the objective
material world itself is an illusion. Both are created by the
inter-action betwe
