"He knew all the arguments of despair and would not listen to them."

"The Mountain crept up ever nearer, until, if they lifted their heavy heads, it filled all their sight, looming vast before them: a huge mass of ash and slag and burned stone, out of which a sheer-sided cone was raised into the clouds. [...] To [Sam's] surprise he felt tired but lighter, and his head seemed clear again. No more debates disturbed his mind. He knew all the arguments of despair and would not listen to them. His will was set, and only death would break it." --J.R.R. Tolkien, The Lord of the Rings: The Return of the King [emphasis mine]
