The Cult of Heroism and the Fear of Death There are several heroes in the Middle Earth Trilogy. To my way of thinking, heroes have to be mortals--their lives must be subject to loss. Gandalf, Elrond, and Galadriel are not mortal. Elves are not mortal. Hobbits, dwarves, and men are mortal. Only those three are potentially heroes.
Aragorn and Frodo are the two great heroes in LOTR, and of the two, Frodo is the greater hero. What elevates their heroism from minor to great is their struggles aim, duration, and intensity. Aragorn endured a lifetime of lonely hardship in service to Sauron's containment and defeat. Frodo, whose peril in relation to his potential gain, was the most disproportionate, had his role thrust upon him. He was "meant" to bear the ring into what might be everlasting suffering, and his fate didn't include a guarantee of success. Further, there was no great reward promised. Aragorn had the reward of marriage and rule of the united kingdoms if he succeeded.
There are numerous minor heroes: Arwen for one. Arwen did not serve in battle, but she surrendered immortality in order to marry the man she loved, Aragorn. (Take that, Edward VIII, you ain't got nothing on Arwen -- you abdicated your figurehead throne for a two-time loser, Wallace Simpson. It isn't like you saved England from the Huns, or something.)
Samwise, Merry, Pippin, Gimli, and Boromir are all minor heroes. Sam is in between great and minor hero. He shared Frodo's trials most intimately, and he had chosen to go with Frodo. Even though it wasn't his fate to complete the task, he helped Frodo all the way to the end. The remaining mortals all advanced the cause of the Ring bearer (even if Boromir caved in to temptation, he did recover his senses after he failed.) There are several characters from the Mark who are minor heroes, too. Not that they weren't brave, but the plot didn't give them the role of Great Hero.
All of the heroes feared death and had to resist the terrors of death nearby.
Can the LOTR be said to model heroism for human beings in the 20th or 21st century?
First, in Tolkien's view, heroism is not a flight from death, not a triumph of the ego. It's the triumph of sacrifice over ego, and the offer of death for victory. The military and the Church both look at heroism the same way: Military heroes and religious martyrs give up their lives (and not by blowing themselves up in a concert hall). Saints spend their lives devoted to the homeless, the hungry, the dying, the sorrowing, the imprisoned; they give up the comfortable lives they could have led. Soldiers get medals -- often posthumously -- for leading the charge against the enemy, or for selflessly covering a grenade with their body and dying, but saving their comrades.
As for the glory of heroism enduring beyond death, many people perform acts of heroism and are forgotten, or are never named because the witnesses are dead. The hero didn't first calculate, "Let's see, how many people are going to notice this magnanimous sacrifice on my part? It has to be at least 300, or it's just not worth it." Or, there is evidence of people saving others, even though their efforts would be lost to history, as far as they knew. (Nobody reported it, it was surmised from the evidence.)
