What is the sentence in the lion the witch and the wardrobe has the word inclined in it?

In "The Lion, the Witch, and the Wardrobe" by C.S. Lewis, the Word "inclined" is used in the sentence: "The Beaver, on his side, really didn't know any more about the whole thing than the children did; but the moment the Robin had spoken, he nodded very slightly—not so much to tell them he agreed, as because he was too much a Beaver to go back on what he had once said."
