oneness of space and time, is the predicate of
all _real_ being.

But as little can we conceive the oneness, except as the mid-point
producing itself on each side; that is, manifesting itself on two opposite
poles. Thus, from identity we derive duality, and from both together we
obtain polarity, synthesis, indifference, predominance. The line is Time +
Space, under the predominance of Time: Surface is Space + Time, under the
predominance of Space, while Line + Surface as the synthesis of units, is
the circle in the first dignity; to the sphere in the second; and to the
globe in the third. In short, neither can the antagonists appear but as
two forces of one power, nor can the power be conceived by us but as the
equatorial point of the two counteracting forces; of which the
_hypomochlion_ of the lever is as good an illustration as anything can be
that is thought of _mechanically_ only, and exclusively of life. To make
it adequate, we must substitute the idea of positive production for that
of rest, or mere neutralization. To the fancy alone it is the null-point,
or zero, but to the reason it is the _punctum saliens_, and the power
itself in its eminence. Even in these, the most abstract and universal
forms of all thought and perception--even in the ideas of time and space,
we slip under them, as it were, a _substratum_; for we cannot think of
them but as far as they are co-inherent, and therefore as reciprocally the
measures of each other. Nor, again, can we finish the process without
having the idea of _motion_ as its immediate product. Thus we say, that
time has one dimension, and imagine it to ourselves as a line. But the
line we have already proved to be the productive synthesis of time, with
space under the predominance of time. If we exclude space by an abstract
assumption, the time remains as a spaceless point, and represents the
concentered power of unity and active negation, _i.e._ retraction,
determination, and limit, _ab intra_. But if we assume the time as
excluded, the line vanishes, and we leave space dimensionless, an
indistinguishable ALL, and therefore the representative of absolute
weakness and formlessness, but, for that very reason, of infinite capacity
and formability.

We have been thus full and express on this subject, because these simple
ideas of time, space, and motion, of length, breadth, and depth, are not
only the simplest and universal, but the necessary symbols of all
philosophic construc
