This is a quote from Bertrand Russell:
It is not only colours and sounds and so on that are absent from the scientific world of matter, but also space as we get it through sight or touch. It is essential to science that its matter should be in a space, but the space in which it is cannot be exactly the space we see or feel. To begin with, space as we see it is not the same as space as we get it by the sense of touch; it is only by experience in infancy that we learn how to touch things we see, or how to get a sight of things which we feel touching us. But the space of science is neutral as between touch and sight; thus it cannot be either the space of touch or the space of sight. (Source: The Problems of Philosophy)
I am not sure I understand what "as between touch and sight" mean here. Did the author mean: "as it is between touch and sight"? Can someone reword it. It seems some word were taken out for brevity sake.
