“He always had a problem with the purity of others. Never his own.”

“...it gratified him to feel like a desperate man. He had got into the habit of seeing himself always in desperate straits. His unhappy temperament was like a cage; he could never get out of it; and he felt that other people, his wife in particular, must have put him there. It had never more than dimly occurred to Frank that he made his own unhappiness.”

“He who is concerned only with the purity of his own life ruins the great human relations.”

“He that always gives way to others will end in having no principles of his own. ”

“Existence alone had never been enough for him; he had always wanted more. Perhaps it was only from the force of his desires that he had regarded himself as a man to whom more was permitted than to others.”

“He had a problem, like any other problem. The problem just hadn't been well posed. The problem was: Should he leave Penny or not?”
