Babbitt

In contrast to the complacent Myra he saw her as swift and air-borne and radiant, a fire-spirit tenderly stooping to the hearth, and however pitifully he brooded on his wife, he longed to be with Tanis.†
Chpt 30 *

in contrast = in a comparison that shows differences

His wife was awake, her face sallow and lifeless in the morning light, but now he did not compare her with Tanis; she was not merely A Woman, to be contrasted with other women, but his own self, and though he might criticize her and nag her, it was only as he might criticize and nag himself, interestedly, unpatronizingly, without the expectation of changing—or any real desire to change—the eternal essence.†
Chpt 33
