All grown-ups were once children (but only few of them remember it).
What a distressing contrast there is between the radiant intelligence of the child and the feeble mentality of the average adult.
Children are educated by what the grown-up is and not by his talk.
The lover of nature is he whose inward and outward senses are still truly adjusted to each other; who has retained the spirit of infancy even into the era of manhood.
Children should always show great forbearance toward grown-up people.
