The suggestion that the normal human brain has an almost infinite capacity is important: it means that almost everyone is educable. Given enough time and the right opportunities, everyone can learn anything. It is a sad commentary on the training and teaching profession that so many people feel that they are incapable of learning; surely our teaching and instruction is at fault when we reject someone as a failure. How can we say they have not learned when we have used only a small part of the learner's mental capacity. Mea culpa.
