The Fellowship of the Ring by J.R.R Tolkien (Harper Collins 1991) pp. 260-263
All who have participated in the great debate, finding “counsel for the peril of the world”, have spoken either of hiding the Ring or of destroying it, but there is one last option to be debated and it is Boromir who offers that option.
“Why do you speak ever of hiding and destroying? Why should we not think that the Great Ring has come into our hands to serve us in our hour of need? Wielding it the Free Lords of the Free may surely defeat the Enemy. That is what he most fears, I deem.”

And Boromir is right. Sauron does fear that one of his deadliest foes will take the Ring and then u7se it against him and he knows that among his enemies there are those capable of doing so. He knows that he only has a certain amount of time available to him to defeat them before what he regards as the inevitable happens. He knows that only one person can wield the Ring at any point. Gandalf was right when he said this to Saruman. But he knows also that before that moment comes there will be a struggle to be that one person. If he can strike with sufficient force while the struggle is taking place he can both defeat his enemies and regain the Ring.
But this is not how the Wise reply to Boromir. Elrond simply rejects Boromir’s proposal out of hand.
“We cannot use the Ruling Ring… It belongs to Sauron and was made by him alone, and is altogether evil.”

What Elrond rejects is the notion that one side in the struggle is good and right and the other side is bad and wrong. The good guys versus the bad guys. As Gandalf will say to Denethor later on, “I pity even his (that is Sauron’s) slaves”. In a straight forward us and them conflict there is only one question and that is the question of power. As Boromir puts it, “Valour needs first strength, and then a weapon.” As far as Boromir is concerned the Ring is a perfectly legitimate weapon. It gives “us” the means to defeat “them”. Boromir does not make this argument but there have been those who have argued that it is morally irresponsible not to seek to be as powerful as possible. To reject power is effectively to give in to those who will then use power against us. This was used as an argument against nuclear disarmament during the Cold War. To disarm, it was said, was irresponsible both morally and practically. Although Boromir does not make this argument himself there is little doubt that if it had been made at the Council Boromir would have agreed with it.
Some critics have argued that Tolkien meant the Ring to be an allegorical representation of nuclear weapons and that The Lord of the Rings was more or less a lengthy tract against the making and the use of such weapons. C.S Lewis in a critical essay of his own pointed out that Tolkien had been creating his mythology and pondering the question of the nature of evil long before he finally wrote his story and long before the atomic bomb was first conceived and used. To Tolkien the bomb was simply one more example, albeit a significant one, of the way in which power is gained and used by human beings. It is Gandalf who speaks more nearly of the nature of evil when he speaks of Sauron thus.
“He is very wise, and weighs all things to a nicety in the scales of his malice. But the only measure that he knows is desire, desire for power; and so he judges all hearts.”
It is the desire for power, power over others, that lies at the heart of the nature of evil. The Ring is the quintessential expression of this desire. How might a person achieve complete power over others? Surely it is by the possession of something that might grant that power. The Ring is both the desire for that power and it is the power itself. Thus it is utterly corrupting. To use it would be disastrous. To hide it would allow that corruption to persist. There is only one course of action open and that is to destroy it.
