Success is thy proof: argue not; convert not; talk not over much! Them that seek to entrap thee, to overthrow thee, them attack without pity or quarter; & destroy them utterly. Swift as a trodden serpent turn and strike! Be thou yet deadlier than he! Drag down their souls to awful torment: laugh at their fear: spit upon them!

Aleister Crowley, Liber AL vel Legis sub figura CCXX, The Book of the Law, III.42
