As the moral gloom of the world overpowers all systematic gaiety, even so was their home of wild mirth made desolate amid the sad forest.

Hawthorne contrasts exuberant, even “wild,” human merriment with an enveloping moral darkness that ultimately prevails. The sentence suggests that cheerfulness arranged as a program (“systematic gaiety”) is fragile when set against the world’s deeper burdens—guilt, sorrow, conscience, or the pervasive sense of sin that Hawthorne often explores. The image of a once-lively home becoming “desolate amid the sad forest” turns the natural setting into a moral landscape: the forest is not merely scenery but a symbol of isolation and melancholy that can swallow communal joy. The effect is elegiac, implying that mirth can be temporary shelter, but not a lasting defense against moral or existential gloom.
