ABSTRACT
In this chapter, the author begins the evidence for a mind in cerebral hemisphere with the most basic of tests on a split-brain patient. Whichever hemisphere was being tested, split-brain patients were conscious of their environment, using sight, hearing, and touch. The differences in the linguistic abilities of the two hemispheres must not be allowed to cloud the similarities between them, and the clear evidence of the presence of a mind in each hemisphere. In particular, the difference in linguistic abilities provides us with an important diagnostic tool. If there is no damage to the language centres in the left hemisphere, then the inability of a subject to describe in words what he has sensed, and what has clearly influenced his behaviour, shows that it was the R-mind that did the sensing and initiated the behaviour.
