A state in which the thoughts, expressions, and actions are wild, irregular, and incoherent; mental aberration; a roving or wandering of the mind, -- usually dependent on a fever or some other disease, and so distinguished from mania, or madness.
When you are overworked and exhausted, there is a sense of kind of delirium and that's why I think architects do all-nighters and they kind of do those deadlines. For four days I remember doing four nights in one row with no sleep. I mean nobody, unless you are crazy, would do that, but you are totally focused on the project. Zaha Hadid
There is in every madman a misunderstood genius whose idea, shining in his head, frightened people, and for whom delirium was the only solution to the strangulation that life had prepared for him. Antonin Artaud
Slums may well be breeding grounds of crime, but middle class suburbs are incubators of apathy and delirium. Cyril Connolly
To hell with reality! I want to die in music, not in reason or in prose. People don't deserve the restraint we show by not going into delirium in front of them. To hell with them! Louis-Ferdinand Celine
