For the blind, space and time are identical. The reason a blind person would imagine a typewriter 100 feet away as the same size as one 1 foot away is because the only time a blind person has ever experienced a typewriter at all is when it was at arms length. The idea of perspective is totally foreign to them. The connection between space and time comes from this extreme locality of the sensory world of the blind. If walking down a hallway, they can not perceive the end of it, and can only perceive the region they are currently in contact with. As they walk down the hallway, they learn that 2 seconds down there is a light fixture, 8 seconds down there is a bump in the carpet, and at 14 seconds the hallway ends. Intuitively, the concepts become very strongly linked. Oliver Sacks discusses this in some of his books. I think the most informative thing about this is that it is completely consistent with a view of the brain as an associative engine - stimulus which occurs together gets associated with each other, and presence of one stimulates an expectation of the others.
