The poem tells the listener not to accept death passively. It uses imagery of night representing death and urges one to "rage, rage against the dying of the light." Wise men know death is inevitable but shouldn't just accept it if they haven't achieved their full potential. Earlier generations cry out at the end of their lives about deeds left undone. Wild, lively men celebrate life but learn too late that it is fleeting. Even when nearing death, one should continue fighting against their impending demise.
