Gletkin believes that prisoners have to be motivated in order to be forced to confess. Gletkin has noticed that if prisoners are forced to face the reality of execution they will often confess to avoid such a fate. Gletkin also believes that prisoners who are made uncomfortable in some way, such as not being allowed to sleep for more than an hour or two at a time, will also confess quickly. Ivanov does not hold with Gletkin's methods. Ivanov believes that logic will work better with a man like Rubashov because he has always used logic in making his choices in the past. In the end, however, Ivanov is executed for his beliefs, while Gletkin gets what he wanted from Rubashov.
