The Moonstone
by
Wilkie Collins
Give not thyself up, then, to fire, lest it invert thee, deaden thee; as for the time it did me. There is a wisdom that is woe; but there is a woe that is madness.

Moby Dick
by
Herman Melville
No mercy, no power but its own controls it. Panting and snorting like a mad battle steed that has lost its rider, the masterless ocean overruns the globe.

"They think me mad--Starbuck does; but I'm demoniac, I am madness maddened! That wild madness that's only calm to comprehend itself!"

Herman Melville
Is he mad? Anyway there's something on his mind, as sure as there must be something on a deck when it cracks.

Moby Dick
by
Herman Melville
"You said I killed you - haunt me, then! The murdered do haunt their murderers, I believe. I know that ghosts have wandered on earth. Be with me always - take any form - drive me mad! only do not leave me in this abyss, where I cannot find you!"
~
Wuthering Heights
by
Emily Bronte
Is Mr. Heathcliff a man? If so, is he mad? And if not, is he a devil? I sha'n't tell my reasons for making this inquiry; but I beseech you to explain, if you can, what I have married.

Wuthering Heights
by
Emily Bronte
"I have learned not to think little of any one's belief, no matter how strange it may be. I have tried to keep an open mind, and it is not the ordinary things of life that could close it, but the strange things, the extraordinary things, the things that make one doubt if they be mad or sane."
~
Dracula
by
Bram Stoker
Was I to believe him in earnest in his intention to penetrate to the centre of this massive globe? Had I been listening to the mad speculations of a lunatic, or to the scientific conclusions of a lofty genius? Where did truth stop? Where did error begin?
