Spock: I am what I am, Leila, and if there are self-made purgatories, then we all have to live in them. Mine can be no worse than someone else's.

Starbuck, first mate: To be enraged with a dumb brute that acted out of blind instinct is blasphemous.
Captain Ahab: Speak not to me of blasphemy, man; I'd strike the sun if it insulted me. Look ye, Starbuck, all visible objects are but as pasteboard masks. Some inscrutable yet reasoning thing puts forth the molding of their features. The white whale tasks me; he heaps me. Yet he is but a mask. 'Tis the thing behind the mask I chiefly hate; the malignant thing that has plagued mankind since time began; the thing that maws and mutilates our race, not killing us outright but letting us live on, with half a heart and half a lung.

no beast so fierce but knows some touch of pity. But I know none, and therefore am no beast." -William Shakespeare's Richard III
