The ideal of mental hygiene is the development of the best mental condition in everyone; meaning by mental, not merely the intellectual powers, but all the processes, affective, emotional, volitional, which in popular speech are comprehended under the term "mental." The author discusses educational means of mental hygiene, remarking the value to the child of a wholesome social environment; an environment which provides desirable patterns for imitation, and which includes sufficient understanding of the child's interests, without an excessively close emotional atmosphere. And always, explanation to the child, understanding on his part, and practice, naturally encourage the development of such habits and attitudes as conserve living.
