I would put a child into a library (where no unfit books are) and let
him read at his choice. A child should not be discouraged from reading
anything that he takes a liking to, from a notion that it is above his
reach. If that be the case, the child will soon find it out and desist;
if not, he of course gains the instruction; which is so much the more
likely to come, from the inclination with which he takes up the
study.--S. JOHNSON. (Boswell's _Life_.)
