And, just as was the case with the idea of Time, we find it most difficult--if not indeed impossible--to form an idea of an Omnipresent--of That which occupies Infinite Space. This because everything that our minds have experienced has had dimensions and limits. The secret lies in the fact that Space, like Time, has no real existence outside of our perception of consciousness of the relative position of Things--material objects. We see this thing here, and that thing there. Between them is Nothingness. We take another object, say a yard-stick, and measure off this Nothingness between the two objects, and we call this measure of Nothingness by the term Distance. And yet we cannot have measured Nothingness--that is impossible. What have we really done? Simply this, determined how many lengths of yard-stick could be laid between the other two objects. We call this process measuring Space, but Space is Nothing, and we have merely determined the relative position of objects. To "measure Space" we must have three Things or objects, _i.e._, (l) The object from which we start the measure; (2) The object with which we measure; and (3) The object with which we end our measurement. We are unable to conceive of Infinite Space, because we lack the third object in the measuring process--the ending object. We may use ourselves as a starting point, and the mental yard-stick is always at hand, but where is the object at the other side of Infinity of Space by which the measurement may be ended? It is not there, and we cannot think of the end without it. Let us start with ourselves, and try to imagine a million million miles, and then multiply them by another million million miles, a million million times. What have we done? Simply extended our mental yard-stick a certain number of times to an imaginary point in the Nothingness that we call Space. So far so good, but the mind intuitively recognizes that beyond that imaginary point at the end of the last yard-stick, there is a capacity for an infinite extension of yard-sticks--an infinite capacity for such extension. Extension of what? Space? No! Yard-sticks! Objects! Things! Without material objects Space is unthinkable. It has no existence outside of our consciousness of Things. There is no such thing as Real Space. Space is merely an infinite capacity for extending objects. Space itself is merely a name for Nothingness. If you can form an idea of an object swept out of existence, and nothing to take its place, that Nothing would be called Space, the term implying the possibility of placing something there without displacing anything else.
