Context

“He had not thought of that girl a single time since the day when she had conducted him to the Rue Plumet, he had not seen her again, and she had gone completely out of his mind. He had no reasons for anything but gratitude towards her, he owed her his happiness, and yet, it was embarrassing to him to meet her. It is an error to think that passion, when it is pure and happy, leads man to a state of perfection; it simply leads him, as we have noted, to a state of oblivion. In this situation, man forgets to be bad, but he also forgets to be good. Gratitude, duty, matters essential and important to be remembered, vanish.” source
