Last wordism is the belief that victory can be obtained in a debate or discussion by having the "last word." Some argue that last wordism is often a characteristic of "less intellectually robust presentations." Andrew Schlafly tries to quit while he is ahead by accusing people of last wordism, when only they are presenting their counterargument.
Last wordism reflects a lack of restraint, a characteristic of wrongdoing or sin. The ultimate in last wordism was the Crucifixion of Jesus, to which He responded with the Resurrection. Jesus is the ultimate example of last wordism.
