My eyes are dim with childish tears. [ Wordsworth ]

Lofty thought lies oft in childish play. [ Johann C. F. Von Schiller ]

Age makes us not childish, as some say; it finds us still true children. [ Goethe ]

Age does not make us childish, as people say; it only finds us still true children. [ Johann Wolfgang von Goethe ]

Childish, imbecile carelessness is enough to render any man poor, without the aid of a single positive vice. [ Francis Wayland ]

The vanity of loving fine clothes and new fashions, and valuing ourselves by them, is one of the most childish pieces of folly that can be. [ Sir Matthew Hale ]

There are chords in the human heart - strange varying strings - which are only struck by accident; which will remain mute and senseless to appeals the most passionate and earnest, and respond at last to the slightest casual touch. In the most insensible or childish minds there is some train of reflection which art can seldom lead or skill assist, but which will reveal itself, as great truths have done, by chance, and when the discoverer has the plainest and simplest end in view. [ Dickens ]
