Othello

Space-ships and time machines are no escape from the human condition. Let Othello subject Desdemona to a lie-detector test; his jealousy will still blind him to the evidence. Let Oedipus triumph over gravity; he won't triumph over his fate.

—Koestler, Arthur

[a character in Mr Puff's play within a play,'The Spanish Armanda'] Perdition catch my soul but I do love thee. : Haven't I heard that line before? : No, I fancy not.öWhere pray? :Yes, I think there is something like it in Othello. : Gad! now you put me in mind on't, I believe there isöbut that's of no consequence; all that can be said is, that two people happened to hit upon the same thoughtöand Shakespeare made use of it first, that's all.

—Sheridan, Richard Brinsley
