It is precisely zero to which Nature continually strives to revert, and to which it would revert, if the antithesis were ever cancelled. Let us suppose the original condition of Nature = 0 (want of reality). Now zero can certainly be thought as dividing itself into 1 - 1 (for this = 0); but if we posit that this division as not infinite (as it is in the infinite series 1 - 1 + 1 - 1 ...), then Nature will as it were oscillate continually between zero and unity—and this is precisely its condition.
