I could not help laughing at this remark, made in all seriousness; but he went on, walking up and down the room like a caged beast, intent on expressing what he felt, but found such difficulty in putting coherently.

"When a woman loves you she's not satisfied until she possesses your soul. Because she's weak, she has a rage for domination, and nothing less will satisfy her. She has a small mind, and she resents the abstract which she is unable to grasp. She is occupied with material things, and she is jealous of the ideal. The soul of man wanders through the uttermost regions of the universe, and she seeks to imprison it in the circle of her account-book. Do you remember my wife? I saw Blanche little by little trying all her tricks. With infinite patience she prepared to snare me and bind me. She wanted to bring me down to her level; she cared nothing for me, she only wanted me to be hers. She was willing to do everything in the world for me except the one thing I wanted: to leave me alone."

请教老师：

...in putting coherently 这里的put为什么是不及物动词？词典均显示put是及物动词。另外，不懂这句and nothing less will satisfy her. nothing less 是什么意思和用法？
