No one suspects or dreams what mighty powers there are latent in us all, or how easily they may be developed.

It would not be so reprehensible if men entirely neglected the subject, but they are always working hard and spending millions on the old system, and will not even make the least experiment to test a new theory.

One reason for this is the old belief that we are all born with a certain quantum of "gifts," as for example memory, capacity, patience, _et cetera_, all more or less limited, and in reality not to be enlarged or improved.

The idea is _natural_, because we see that there are very great differences, hereditary or otherwise, in children.

But it is false.
