Paradise Lost

In lines 120-228, Belial is giving his opinion of what the fallen demons should do.  In his argument, he states that "Our purer essence then will overcome / Thir noxious vapour, or endur'd not feel, / Or chang'd at length, and to the place conformd / In temper and in nature, will receive / Familiar the fierce heat, and void of pain; / this horror will grow milde, this darkness light" (215-220).  Basically what Belial thinks they should do is nothing.  He argues that eventually, they will get used to hell and it will become less horrible than it seems to be now.  In his long speech he also points out that if they go to war again, their punishment from God could only get worse.  He believes that by doing nothing, things cannot get any worse, only better or more bearable.
