(524) Most true. This was what I meant when I spoke of impressions which invited the intellect, or the reverse—those which are simultaneous with opposite impressions, invite thought; those which are not simultaneous do not. I understand, he said, and agree with you. And to which class do unity and number belong? I do not know, he replied. Think a little and you will see that what has preceded will supply the answer; for if simple unity could be adequately perceived by the sight or by any other sense, then, as we were saying in the case of the finger, there would be nothing to attract towards being; but when there is some contradiction always present, and one is the reverse of one and involves the conception of plurality, then thought begins to be aroused within us, and the soul perplexed and wanting to arrive at a decision asks ‘What is absolute unity?’ This is the way in which the study of the one has a power of drawing and converting the mind to the contemplation of true being. And surely, he said, this occurs notably in the case of one; for we see the same thing to be both one and infinite in multitude? Yes, I said; and this being true of one must be equally true of all number? Certainly. And all arithmetic and calculation have to do with number? Yes.

(9) For the One is indivisible; wherefore also it is infinite, not considered with reference to inscrutability, but with reference to its being without dimensions, and not having a limit. And therefore it is without form and name.

(6) Moreover, as Infinite Space is invisible and beyond the other senses, it cannot be "known" or cognized as a Thing. Thought regarding it must always report "not this; not that" regarding it; and it answers to the ancient sage's statement of Reality that: "The Essence of Being is without attributes, formless, devoid of distinctions, and unconditioned. It is different from that which we know, and from that which we do not know. Words and thought turn from it without finding it. The wise answer only by silence all questions concerning its nature. To all suggestions concerning its qualities, properties, and attributes, the wise simply answer: 'neti, neti'—'not this, not that!' Of THAT the wise assert simply 'It IS.'" And as other ancient sages have said: "The imagination, the understanding, and abstract thinking will always strive in vain to represent the Infinite; for no form of finiteness (to which thought and speech also belong) can express the Infinite; nor can that which was timed express the Timeless and Eternal; nor can thought resultant from the chain of causation grasp the Causeless or Self-Existent." So, in every way, and from every angle of view, we discover that the concept of Infinite Space is a noble and worthy symbol of THAT which we mean when we try to think of the Infinite Unmanifest—of the Essence of Being before Manifestation into Activity and Form.
