'so much novelty to feel and learn'

His honest, warm, and intelligent nature shook off rapidly the clouds of ignorance and degradation in which it had been bred; and Catherine's sincere commendations acted as a spur to his industry. His brightening mind brightened his features, and added spirit and nobility to their aspect: I could hardly fancy it the same individual I had beheld on the day I discovered my little lady at Wuthering Heights, after her expedition to the Crags. While I admired, and they laboured, dusk drew on, and with it returned the master. He came upon us quite unexpectedly, entering by the front way, and had a full view of the whole three, ere we could raise our heads to glance at him. Well, I reflected, there was never a pleasanter, or more harmless sight; and it will be a burning shame to scold them. The red fire-light glowed on their two bonny heads, and revealed their faces, animated with the eager interest of children; for, though he was twenty-three, and she eighteen, each had so much novelty to feel and learn, that neither experienced nor evinced the sentiments of sober disenchanted maturity.

—Emily Bronte, Wuthering Heights (1847)
