And if great reasoners are often maniacal, it is equally true that maniacs are commonly great reasoners. When I was engaged in a controversy with theon the matter of free will, that able writer Mr. R. B. Suthers said that free will was lunacy, because it meant causeless actions, and the actions of a lunatic would be causeless. I do not dwell here upon the disastrous lapse in determinist logic. Obviously if any actions, even a lunatic's, can be causeless, determinism is done for. If the chain of causation can be broken for a madman, it can be broken for a man.
